Anyone who has held their hand out of a car into the wind to play airplane already has a fundamental impression of control surfaces on the airplane.
When the heel of the palm went down, the airpressure under the hand pushed the hand up. That's called lift. The airflow over/under the hand changes with the shape of the hand or airfoil. If you had little cut-outs near your wrist, there wouldn't be as much lift.
The tail section contains control surfaces for keeping the plane stable and controllable.
1) Horizontal: The horizontal, non-moving part is called the stabilizer, and it prevents uncontrolled up-and-down motion of the nose. The small hinged sections on each side are called elevators, which work in unison. It is controlled by the cockpit control wheel/stick and increases or decreases lift. When forward pressure is applied on the wheel, the elevators move downward, which increases the length of the tail causing more lift, which forces the tail upward, causing the nose to drop. There is also a small hinged section in the elevator which is controlled by a small vertical wheel on the cockpit console which is used to finetune the elebator trim. Hense the name trim tab.
2) Vertical: The vertical non-moving part which prevents the nose from uncontrolled swinging side to side. The large hinged section is the rudder. The rudder is controlled by the foot pedals in the cockpit, and deflects the tail to the right or left.
The wings generate most of the lift to hold the plane in the air. Different models of aircraft will have wings of different shapes and in different vertical locations. On a Cessna, the wing is high, and on a Piper, it is low. On an F14, the can change from a forward angle to "swept back".
On most small planes, the wings also carry the fuel.
There are many control surfaces on a wing:
1) The aileron is the hinged part of the back of the wing towards the tip which is used to roll the wings from side to side. There is one on each side of the plane and they work opposite of each other. When one moves up, the other moves down.
2) Flaps are the hinged sections on the back of the wing near the fuselage. Flaps are deployed downward on takeoff and landing to increase the lift produced by the wing and allows the plane to fly at slower speeds.
3) Spoilers and Slats are used on high performance/commercial aircraft and also changed the aerodynamics of the wing.

Private Jet
High traffic is inevitable at private airports during popular events or holiday seasons (think Super Bowl or winter in Aspen). With that in mind, we have put together some information and helpful tips to ensure that your private jet travel to bustling airports is both relaxing and stress-free.
"What is an STMP?" Special Traffic Management Programs (STMP's) are implemented for special events that attract thousands of people and aircraft to participating airports. The FAA requires users to make arrival and departure reservations to and from these airports to manage the flow of arrivals and departures for these events.
"What is a slot time?" Slot times refer to airports expecting high traffic volume due to special events or seasonal activity. Slot times are issued to stagger incoming flight traffic in order to relieve air traffic control duties. Slot time reservations are typically available 72 hours prior to the estimated time of arrival.
Private Jet Travel Tips:
• Be flexible with your departure time requests. Allow a window for departure times. Slot times will not be assigned more than 72 hours in advance to the flight departure request.
• Avoid changing flight dates & times. Slot times are valuable and go quickly, so try to stick to your flight schedule to avoid conflicts.
• Arrive on time. Particularly in mountainous areas, weather can change rapidly. The closer you leave to your intended time, the better opportunity you have to guarantee your arrival time. So if your slot departure is 8am, please allow time for boarding so the jet will be ready and in position for an 8am departure.

UFO
What comes to mind when someone talks about a UFO? Do you think about the cover of a science fiction novel and the image of mysterious bluish lights beaming down from it? Do you think about a time when you were out late at night and you saw a flash of light, wondered what it was only to realize a moment later that what you saw wasn't a UFO - it was just the lights of a plane that was beginning its descent. Do you think of movies, or little green men, cartoons, or do you just turn away shaking your head?
A lot of people discuss UFOs as flying saucers - it seems to be the best description that they can come up with. Others suggest, rather dismissively, that UFO simply means unidentified flying object and that the light that someone saw flashing in the sky was either a plane, a helicopter or a reflection of light off of a cell phone tower or another metal object.
Reflections of light from a cell phone tower do little to explain away "mysterious materials" found in Roswell, New Mexico in the late 1940s. While the United States military has always stood their ground that these materials were merely fragments of a research balloon, a top secret test that ended badly, others offer another explanation. They assert that the materials were fragments of a UFO, an alien craft that crashed rather than safely landing. They believe that the "flying disc" - as it was called by military personnel - that was recovered could not be something from this world, and so began one of the most talked about UFO encounters in the world.
Many who believe that the UFO in Roswell, New Mexico deserved more attention than it was being given, believe that it wasn't something that could just be dismissed. In part, this is likely to have something to do with other stories surrounding the flying saucer. A farmer talked about having found materials miles away from Roswell, and the story was picked up by newspapers, accompanied by photos of the strange find - strips of rubber, something like aluminum foil, sticks. It's a story that has gained so much attention around the world that it has influenced many people's sense of alien life and alien visitations to earth.
If the Roswell, New Mexico story had never become so widespread, UFO and flying saucer may not be so common in our language, in our experiences and in novels, television programming and films. How common is it for people to see a UFO?
It's hard to say, really, because many people who see an unidentified flying object in the sky are reluctant to report it. Either the person who saw a UFO believes that there is a far more logical explanation or merely thinks that no one would believe them if they were to say anything about it. And yet, there are UFO sightings that are shared and that become the topic of conspiracy theories by those who believe that beings from other planets and galaxies have visited the earth.
One such incident occurred in 1980 in Rendlesham Forest in Suffolk, England. Those who saw the UFO all claimed to have seen flashing lights coming from an unidentified flying object that was descending towards the woods - a UFO that was roughly the size of a car and seemed to float on a beam of light. After reports were made about the object, it was discovered that trees were damaged, radio frequencies became nothing but static and soil samples later showed radioactive activity.
Similarly, in Gulf Breeze, Florida in 1987 tales of a UFO began to circulate when a man saw a strange light coming from his lawn. When he saw the flying saucer, he grabbed a camera and started shooting photos as proof of what he had seen. Of course, in this situation, the story was not just of a UFO sighting, but about repeated experiences and of the man's being beamed up onto the craft.
Though discussions of these UFO sightings continue, and there has been audio recordings and photo documentation, it is still difficult to know whether or not the unidentified flying objects were indeed from space. Many claimed, in regard to the Gulf Breeze, Florida UFO sightings, that the man had manipulated the photographs and fabricated the story.
In each case, both sides - the believers and the skeptics - find evidence to support their claims. Those who believe in UFOs and alien visitations cite facts that they claim cannot otherwise be explained. Those who are skeptical offer their own explanations along with their own supporting evidence. Which side is right? For now, that's up to you to decide.

Style of Biker
From touring to off-road riding to track riding to cyclo-riding to recreational biking—there are almost as many different styles of riding as there are bikes. The following is a discussion of three of the most popular styles of biking today.
Street/Urban Riding
Street/Urban riding is when you bike through urban areas, ride on ledges and other man-made obstacles. Some riders execute tricks as well as stalls and grinds. Hybrid bikes, sometimes called city bikes, are typically used for street/urban riding. Hybrid bikes are a cross between a mountain bike and a road bike. Most have front suspension with wide comfortable seats and upright handlebars.
Free Riding
The essence of free riding has it origins on the shores of British Columbia. As some free riders have explained it, free riding is more than just riding, it’s about riding with your friends and doing things on your bike that push the limits of both yourself and your bike. It’s not about being the fastest or coming up with a new trick. Rather, it’s about being totally free on your bike. Free riding is different for everyone. Essentially, when you ride for pure enjoyment, do your own thing, in your own way, that’s free riding--making it more of a mindset than a structured style of riding. For example, you could free ride downhill, cross-country or down the boardwalk in Ocean City, Maryland.
Many free ride bikes closely resemble downhill bikes and weigh as much, although they are usually designed to be easier to pedal. Free ride bikes should be in the 30 to upper 50 pound range, have a steeper angled frame in order to make maneuvering on narrow obstacles possible, and be built from stronger, heavier materials.
Downhill Mountain Biking
If you think downhill biking is all about kicking back, stretching your arms and cruising at a leisurely pace, think again. Even though it’s all downhill, biking down a mountain demands concentration, quick reflexes and bike-handling skills much different than free riding or city riding. It’s also a blast! Downhill mountain biking races involve race courses that are designed for riders to speed down while navigating huge jumps, obstacles and more. It’s very similar to motor cross racing.
While it’s true that all bikes go downhill, bikes that provide the optimum ride for Downhill Mountain Biking have what is called full suspension. This means that the front and rear of the frame are equipped with shock absorbers.

Buying Tips
The Right Bike for You
Want to buy a bike but don’t know where to begin? Maybe a friend of yours recommends getting a certain bike, while another biking buddy insists that his bike is the best choice for you. Who do you listen to? How about neither? What you need to do is sit down, relax and figure out what your priorities and preferences are to determine what bike is going to work best for you. Here are some points you will definitely want to consider before you pick out your new set of wheels.
What’s Your Riding Style?
Start by asking yourself why you want to ride to begin with. Is it for exercise? Do you want to fly through the air for the thrill or the sport of it? Where are you going to ride? Through city streets or back road trails? Once you define your style of riding, it will be easier for you to choose the kind of bike you need.
There Are a Variety of Bike Options Available
Although there is a multitude of bike styles, the following are some of the most popular:
Mountain Bikes: These are durable bikes you can take off the road. Mountain bikes have fat tires, comfortably wide handlebars, and low gears for easier navigation of hills.
Road Bikes: If you plan on doing long rides, pavement riding, this is the bike for you. Road bikes are built for speed, have thinner tires and handlebars, and are overall, much lighter in weight.
Hybrid Bikes: This type of bike combines the features of mountain bikes and road bikes. Hybrid bikes are perfect for those who want to experiment with all styles of riding.
Cruisers: These bikes are generally one speed and are constructed for literally just that—cruising.
Comfort Bikes: These are specialty mountain bikes or hybrids that offer more upright riding and softer seats. These bikes are essentially designed for riders who desire more comfort in their ride.
Size Matters
Some bike models offer up to eight different sizes. To determine the right size for you, measure your inseam—this will determine the right size frame, in terms of stand-over-height. Like a pair of jeans, the right fit is important.
Ask Questions
Don’t be afraid to ask advice about what you don’t understand, such as quick release, bike maintenance, what kind of equipment you need, etc. Knowing what you need to know is the difference between easy riding and not so easy riding.
Buy a Bike You Like
Take even the smallest details into consideration when buying a bike: how it rides, size, how it looks, color--everything. After all, it’s your set of wheels--ride it proudly.

110cc Pocket Bikes
A 110cc pocket bike is a miniature motorcycle that is becoming increasingly popular. There are even Pocket Bike races held world wide now, with some of the pros taking home thousands of dollars in cash and prizes. 110cc pocket bikes look like they were built for kids, they are typically 38 to 47 inches long and weigh about 50 pounds, but don't let the small size fool you. The 110cc pocket bikes are specifically built for adult drivers.
The 110cc bikes are made in Italy, and can reach speeds of up to 75 miles per hour. The 110cc pocket bikes have a 30 inch wheelbase, which in layman's terms means that you are barely inches from the ground. This definitely adds an adrenaline rush when it comes to high speed turns! Due to their miniature size, riding a pocket bike offers certain thrills that cannot be obtained on a regular motorcycle.
Pocket bike racing is also the most affordable motor sport in existence today, which is no small part why it is also one of the fastest growing. This draws participants from all over the world, offering them the ability to get in on motor sports, when they might not be able to otherwise. Make no mistakes about it, though, riding a pocket bike isn't like riding a regular motorcycle, even though the concept of balancing on two wheels at high speed is the same. Due to its small size, riding a pocket bike requires more balance, self control, agility, and faster reaction times. The adrenaline rush is a major reason many beginning participants become hooked and life-long fans.
Pocket bikes can be suitable for children over the age of nine, as long as they are very carefully supervised. The bikes were designed for adults, and so are set to support up to 300 pounds of weight. 110cc pocket bikes are not designed or intended for street use, these are bikes made for racing on tracks. Protective gear should be worn by both kids and adults at all times. This includes, but is not limited to, helmet, gloves, knee and elbow pads, and leather clothes in case of an accident. While they may look like toys, the 110cc pocket bikes were designed for extreme motor racing, and need to be treated with the same respect accordingly.

Computer Security
Advances in computer technology is a double-edged sword. On one hand, it affords us quick and easy access to numerous conveniences such as bank statements, favorite shopping centers, school and health records, and more. On the other hand, it can also grant the same access to those who aren't supposed to get it. Although it's a rare occurrence, hacking has become the biggest criminal nuisance in computer history.
Make no bones about it. There's nothing innocent or cute about the hacker. Today's hackers aren't the pimply-faced teen rebels that you might be thinking of. Instead, this generation of hackers are grown individuals who are more than likely earning a living by stealing the identities of innocent, law abiding individuals and then selling those identities to others who want to slip by the system. And the only protection against these seedy people is prevention.
Computer security couldn't be more important than it is today and that's why we've taken the time to introduce it to you. You can reduce the probability of experiencing identity theft by making your computer as hacker-proof as possible. All that's needed is a little software and a lot of common sense.
1. Install an anti-virus/anti-spyware program. Anti-virus/anti-spyware software will stop malicious code from downloading and installing onto your computer while you peruse the Internet. Known as viruses, worms, or spyware, this malicious code can destroy important files and render your computer good for only one thing: sending sensitive data back to the server of an identity thief.
2. Don't store sensitive data on your computer in the first place. Should your computer get infected with a virus, worm, or piece of spyware, you can thwart the individuals responsible by not storing your personal information on your PC so that when and if your computer does send back data - it won't be anything valuable. Hackers look for things like full names, social security numbers, phone numbers, home addresses, work-related information, and credit card numbers. If these things aren't saved onto a computer, there's nothing critical to worry about other than restoring your computer to a non-virus condition.
3. Don't open files without scanning them with an anti-virus/anti-spyware program. In the past, the warning was to avoid opening files from people that you don't know. Today it's really not safe to open files from anyone (without scanning the files) because that's how viruses get spread - through files - even by mistake. So even though your co-worker may have emailed a funny video, it's no more safe to open than a video downloaded from a complete stranger. Be safe and scan each and every file you download from the Internet or receive through email regardless of where it came from.
4. Create a barrier between your computer and prying eyes. Anti-virus/anti-spyware programs are only effective after the effect. But you can prevent identity theft from occurring by installing a firewall. A firewall is software that checks all data entering and exiting a computer and it then blocks that which doesn't meet specified security criteria (user-defined rules).1
5. Don't click on website links in spam messages. In an effort to obtain personal information, some spammers will send email that asks you to click on a link. The email messages are often disguised as important messages from well-known online establishments, and they often try to scare their readers into clicking links with threats of closing an account of some sort. Sometimes the links are harmless and attempt to con the reader into volunteering personal information (credit card number), but other times the links attempt to download harmful software onto a computer.
Your best protection against computer crimes is your own knowledge. Hopefully the suggestions above will prompt you into taking appropriate action and into protecting your computer with the suggested tools. In doing so, you'll not only protect yourself, you'll prevent the spread of these malicious activities and protect others at the same time.

Computer Help
Well there's no denying it - No matter how new or how well maintained our computers are, we all encounter computer problems sooner or later. The good news is that we don't have to face them alone. There are a ton of resources available to walk us through computer issues but it may take a little knowledge in knowing how to access them. This article will show you how.
1. Remember help files. It's funny, but people seem to forget that every computer and every program installed on a computer comes with its own help file. Even the operating system of a computer has a help file and it really should be the first place to look for answers. Help files are designed not only to guide the usage of a computer, they're also designed to solve problems. Inside a help file, look for a section called, "Troubleshooting" (or something similar) when you need to resolve an issue. This section is reserved for solving problems specific to the software or hardware that you're using.
2. Product websites. If you're having a problem with a piece of software or with a hardware part, try the website of that software's or hardware's manufacturer. Most (if not all) manufacturer's reserve a portion of cyberspace and dedicate it to support the products that they build. Microsoft's help desk is good example.
3. Fan sites. Fan sites probably isn't a good name for this resource, but you can find websites that are dedicated toward supporting the users of a particular software program or piece of hardware. We've called them "fan sites" because the maintainers of these sites have no affiliation with the manufacturers that they support! Call them what you will, but their free help is immeasurable and without it, we wouldn't have some of the wonderful workarounds and unique problem solving techniques that we have today.
4. Usenet newsgroups. Another underused resource on the Internet, Usenet newsgroups have hundreds of discussion groups dedicated to some of the most popular computer systems, operating systems, hardware manufacturers, and individual software programs. Sometimes, the representatives of these companies participate, but most of the time, the support in this group is user to user, which is just as valid because you're
working with a team of experienced people.
5. Support Lines. Another source for help that we shouldn't forget are the support systems of various manufacturers. You can reach these systems by calling the phone number associated with the product that you're having trouble with. Calls may be free (1-800 or 1-877 number), or they may cost a small fee (1-900).
6. PC support groups or user groups are another option for help. These are groups that meet in libraries, computer stores, or other local areas and they discuss all sorts of issues related with a particular product. Even if you aren't experiencing a computer or software problem, user groups are fun to participate in and they can help you network into other interests such as job or teaching opportunities.
7. Surprisingly, you may even get a helping hand from the salespersons at your local computer store. We don't recommend that you make this your first pit stop when you experience a problem, but we don't recommend that you rule this option out altogether either. Computer salespersons are hired for a reason - and that's their knowledge. Often, these kind folks can help you resolve an issue over the phone and prevent you form having to buy a costly solution.
As you can see, help is easy to find - You've just got to know where to look for it. Most of the contacts within these resources are extremely friendly and willing to take the time to walk you through a problem at little to no cost. From online discussion groups to the files on your own computer, help is often just a click away.
1. Remember help files. It's funny, but people seem to forget that every computer and every program installed on a computer comes with its own help file. Even the operating system of a computer has a help file and it really should be the first place to look for answers. Help files are designed not only to guide the usage of a computer, they're also designed to solve problems. Inside a help file, look for a section called, "Troubleshooting" (or something similar) when you need to resolve an issue. This section is reserved for solving problems specific to the software or hardware that you're using.
2. Product websites. If you're having a problem with a piece of software or with a hardware part, try the website of that software's or hardware's manufacturer. Most (if not all) manufacturer's reserve a portion of cyberspace and dedicate it to support the products that they build. Microsoft's help desk is good example.
3. Fan sites. Fan sites probably isn't a good name for this resource, but you can find websites that are dedicated toward supporting the users of a particular software program or piece of hardware. We've called them "fan sites" because the maintainers of these sites have no affiliation with the manufacturers that they support! Call them what you will, but their free help is immeasurable and without it, we wouldn't have some of the wonderful workarounds and unique problem solving techniques that we have today.

Gaming Etiquette
No, it isn't Ms. Manners to the rescue, nor is it Polite Polly knocking at your noggin. We just know how easy it is to get frustrated or even angry while playing a difficult game, but if we're not careful, that anger and frustration could lead to some butt-ugly moments during a time that's supposed to be amusing. The following is offered in an effort to keep everything fun and entertaining during a session of group play.
1. Encourage each other. Even if you're competing with each other in a boxing match or car race, take time out to congratulate another player for making a smooth or cunning move. There's no need to be a kiss-up, but when tensions are high, and the desire to impress is high, you can help relax any stress just by throwing out a few compliments here and there.
2. Be patient. Your gaming comrades may not be as fast, as coordinated, or as smart as you. So when you notice your regular game pace slowing down, don't criticize. You could quietly plan your next move or you could offer to help if you notice that your buddies seem lost. This will encourage cooperation and relive some of the stress involved with playing a difficult game.
3. Take some breaks. Permitting that your group finds appropriate places in a game to pause, take advantage and get up to stretch, snack, use the john, talk about school, or catch a few silly commercials on television. A long stretch of game play is tiring and stressful at the same time.
4. Play an inclusive game. By that we mean to make efforts to ensure everyone in the group contributes to the game's completion. You never want to make another person feel left out or just hanging around to fill the space. Create opportunities for everyone involved to participate and help play.
5. Listen to others. You may think that you know all the answers about a game or game system, but listen to what others in the group have to say. You just might learn something new.
6. Invite the "weird guy." This bit of advice of course comes after the horrid Virginia Tech massacre. Tales circulating this news event indicate that the young man responsible was a loner and the victim of bullying during his teenage years as well. Sometimes, all it takes to prevent things like this is a simple effort to reach out to someone. We're not suggesting that an invitation to a gaming party would have saved the lives of 33+ college students, but we are suggesting that making an effort to make others feel welcome and wanted is a huge step towards eliminating the isolation known to cause these kinds of senseless acts.
7. Vow to keep the voice level and cursing to a minimum. That almost goes without saying, but to prevent arguments, agree beforehand to not cross the line when it comes to debating about a particular strategy or selecting a game to play. Some of the most serious fights stem from the silliest arguments. But you can prevent a flare up within your group just by maintaining a cool composure during the entire session.
Now see? That's not too bad a list. All the things that we suggested are certainly "do-able" and they really do work to create a calm and enjoyable environment.

Programs Included
The Windows operating systems already comes with a useful collection of pre-installed programs and even some games. But one of the first things that people do is download a butt-load of new programs as soon as a brand new system is plugged in the wall and connected to the Internet. This article looks at some of the programs that are included with most new systems and then asks the reader to consider if they're sufficient.
NotePad and WordPad. All Windows systems include the two text editors, "NotePad," and "WordPad." Notepad is a plain text editor while WordPad is a rich text editor. Both files are capable of opening plain text, however WordPad can open Windows Write files (an earlier version of WordPad) as well as rich text files. WordPad can also save documents as plain text, rich text, and MS Word documents. So with WordPad having the ability to read and create rich text; embed objects (sound, pictures, and video); and manipulate fonts, we have to wonder if other word processors, which do the same thing, are really necessary. Although WordPad is certainly no match for Microsoft Word's internal spell and grammar checker or Word's Internet linking capabilities, we believe it's a great introduction to word processing in general for computer novices.
Address Book. There are hoards of advanced contact database programs floating around the Internet and on store shelves, but Windows provides a completely competent contact database of its own simply known as "Address Book." This small compact utility allows users to organize contacts by name, location, group, or number and it give users ample space to fully describe each. Compared to Microsoft's Access database program, its user-friendly Address Book is a Godsend to new computer users.
Calculator. Calculator has been a Windows accessory even from its first debut in Windows 1.0. For the life of us, we can't figure out why anyone other than a rocket scientist would want to install a different version than this free one that comes pre-installed. Windows calculator has two interfaces: an easy one, and a scientific one. So perhaps a rocket scientist could fare well with Windows Calculator after all!
Paint. Windows' Paint program allows users to make changes to existing graphics, or create brand new ones at no additional cost. Interestingly, we can count at least ten different graphics packages that are more popular and widely used than this free one. While it doesn't offer as many editing tools, it does provide the essentials and it can open/save graphics in .bmp, .gif, and.jpg format (the latter two being the most commonly format used for Internet eye candy).
Media Player. Real Player and QuickTime are the first programs we think of when we think about multimedia. But Windows Media Player, also free and pre-installed, does a fine job at transmitting Internet-bound sound and video. With this application, you can easily listen to .wav files, .midi files, and even tune into a little Internet radio if you like.
System Tools. Although there are too many to list here, Windows provides more than a handful of useful utilities that will monitor system resources, organize files, repair damaged disks, and more. Yet and still, you can easily find similar tools for sale at computer outlets and download libraries.
What's going on here?
The truth of the matter is that the programs pre-installed are great tools for the beginning computer user. At some point down the road, usage will dictate a need for more powerful applications. We may need a word processor that can convert a document into an HTML page or PDF document. We may need a calculator that solves geometric problems. Or we may need a multimedia tool that lets us create our own videos as well as watch them. These capabilities aren't included with new systems, but there's no reason why we can't exploit the tools that we're given to their fullest.

B-2, must ceeeeeeeeeee
Here are some cool b-2 pictures:

Vulture - Unmanned Aircraft!!
Vulture - Unmanned Aircraft!!
--------------------------------------------------------------------------------
Defense Advanced Research Projects Agency (DARPA) of United States is working to develop an unmanned aircraft that is able to stay in air for a period of 5 years at a time. It is one of the most recent inventions of world.
Officials of DARPA has revealed that this aircraft will be known as VULTURE due to its Persistent Pseudo-Satellite Capability . It means that this aircraft will be able to fly over a single area, communicating or performing analysis for years at a time.
Major Obstacles in Project:
Even this project looks appealing to many of you, but there are some serious problems or you can say obstacles in achieving this project.
1) First challenge in front of designers is to figure out some Way to Supply Power to this aircraft during long missions.
2) Another problem is that this aircraft will carry a 1000 pound (450 kg) payload in winds at an altitude of 60,000 to 90,000 feet.
3) Designers have also to sort out the problems regarding Deterioration of Materials during their long-time exposure to stratospheric flight.
In addition to this there may be many challenges during designing of this aircraft.
Daniel Newman: The Man Behind VULTURE
Daniel Newman is the Project Manger of this ambitious project of NASA. In his words: "We want to completely change the paradigm of how we think of aircraft. Aviation has a perfect record - we've never left one up there. We will attempt to break that record". It looks that its time to get out of the traditional "launch - recover - maintain - launch cycle of aircrafts."

Concept Behind Vulture:
Basically Aircrafts operates just like satellites, but the major difference is that these are not regulated by orbital mechanics. You can understandVulture as a Pseudo-Satellite, which operates in the stratosphere and not in the low Earth orbit. This would provide a 65 dB upgrading in communications capability and will increase onboard sensor resolution.
When Will it Become a Reality?
Well, right now NASA has not mentioned any time table when the aircraft will be ready. But for now NASA has worked on the probable design ofVulture
