Background Does the United States Air Force or one of America's intelligence agencies have a secret hypersonic aircraft capable of a Mach 6 performance? Continually growing evidence suggests that the answer to this question is yes. Perhaps the most well-known event which provides evidence of such a craft's existence is the sighting of a triangular plane over the North Sea in August 1989 by oil-exploration engineer Chris Gibson. As well as the famous "skyquakes" heard over Los Angeles since the early 1990s, found to be heading for the secret Groom Lake (Area 51) installation in the Nevada desert, numerous other facts provide an understanding of how the aircraft's technology works. Rumored to exist but routinely denied by U.S. officials, the name of this aircraft is Aurora. The outside world uses the name Aurora because a censor's slip let it appear below the SR-71 Blackbird and U-2 in the 1985 Pentagon budget request. Even if this was the actual name of the project, it would have by now been changed after being compromised in such a manner. The plane's real name has been kept a secret along with its existence. This is not unfamiliar though, the F-117a stealth fighter was kept a secret for over ten years after its first pre-production test flight. The project is what is technically known as a Special Access Program (SAP). More often, such projects are referred to as "black programs." So what was the first sign of the existence of such an aircraft? On 6 March 1990, one of the United States Air Force's Lockheed SR-71 Blackbird spyplanes shattered the official air speed record from Los Angeles to Washington's Dulles Airport. There, a brief ceremony marked the end of the SR-71's operational career. Officially, the SR-71 was being retired to save the $200-$300 million a year it cost to operate the fleet. Some reporters were told the plane had been made redundant by sophisticated spy satellites. But there was one problem, the USAF made no opposition towards the plane's retirement, and congressional attempts to revive the program were discouraged. Never in the history of the USAF had a program been closed without opposition. Aurora is the missing factor to the silent closure of the SR-71 program. Testing such a new radical aircraft brings immense costs and inconvenience, not just in the design and development of a prototype aircraft, but also in providing a secret testing place for aircraft that are obviously different from those the public are aware of. Groom Dry Lake, in the Nevada desert, is home to one of America's elite secret proving grounds. Here is Aurora's most likely test location. Comparing today's Groom Lake with images of the base in the 1970s, it is apparent that many of the larger buildings and hangars were added during the following decade. Also, the Groom Lake test facility has a lake-bed runway that is six miles long, twice as long as the longest normal runways in the United States. The reason for such a long runway is simple: the length of a runway is determined either by the distance an aircraft requires to accelerate to flying speed, or the distance that the aircraft needs to decelerate after landing. That distance is proportional to the speed at which lift-off takes place. Usually, very long runways are designed for aircraft with very high minimum flying speeds, and, as is the case at Edwards AFB, these are aircraft that are optimized for very high maximum speeds. Almost 19,000 feet of the runway at Groom Lake is paved for normal operations. Lockheed's Skunk Works, now the Lockheed Advanced Development Company, is the most likely prime contractor for the Aurora aircraft. Throughout the 1980s, financial analysts concluded that Lockheed had been engaged in several large classified projects. However, they weren't able to identify enough of them to account for the company's income. Technically, the Skunk Works has a unique record of managing large, high-risk programs under an incredible unparalleled secrecy. Even with high-risk projects the company has undertaken, Lockheed has a record of providing what it promises to deliver. Hypersonic Speed By 1945, only a small amount of jets had the capability of reaching speeds of 500mph. In 1960, aircraft that could exceed 1,500mph were going into squadron service. Aircraft capable of 2,000mph were under development and supposed to enter service by 1965. This was a four-fold increase in speed in two decades. From this, the next logical step was to achieve hypersonic speed. The definition of hypersonic isn't as clearly defined as supersonic, but aerodynamicists consider that the hypersonic realm starts when the air in front of the vehicle's leading edges "stagnates": a band of air is trapped, unable to flow around the vehicle, and reaches extremely high pressures and temperatures. The edge of the hypersonic regime lies at a speed of roughly one mile per second - 3,600mph or Mach 5.4. What is regarded by many as the most successful experimental aircraft program in USAF history, the X-15 rocketplane was created in response to a requirement issued by NASA (then NACA) for an air-launched manned research vehicle with a maximum speed of more than Mach 6 and a maximum altitude of more than fifty miles. The X-15 program, which involved three test aircraft, went on to exceed all goals set and provided valuable data which has been used on many high speed/altitude aircraft of today, including NASA spacecraft, and most likely, the Aurora aircraft. In the early 1960s, Lockheed and the USAF Flight Dynamics Laboratory began a hypersonic research program which would provide data on travel at hypersonic speed as well as more efficient shapes for hypersonic vehicles. From this program came the FDL-5 research vehicle, which beared an amazing resemblance to the North Sea Aurora sighting of Chris Gibson. Building on both the FDL-5 Project and Aurora, the aircraft which may have been seen over the North Sea could have been Northrop's A-17 stealth attack plane. Possible forms of hypersonic propulsion that Aurora could be using include: Pulse Detonation Wave Engines Pulsejet Engines Advanced Ramjets Hypersonic Requirements There are three reasons why the North Sea sketch drawn by Chris Gibson is the most persuasive rendition of the Aurora vehicle. Firstly, the observer's qualifications, with which he couldn't identify the aircraft; which would have been instantaneous if the aircraft was known to the "white world". Second is the fact that the North Sea aircraft corresponds almost perfectly in shape and size to hypersonic aircraft studies carried out by McDonnell Douglas and the USAF during the 1970s and 1980s. The third factor is that the North Sea aircraft looks unlike anything else. No aircraft other than a high-supersonic vehicle, or a test aircraft for such a vehicle, has ever been built or studied with a similiar planform. At hypersonic speeds, traditional aerodynamic design gives way to aero-thermodynamic design. In order for a hypersonic vehicle to remain structurally intact at such high speeds and stresses, the vehicle must produce minimum drag and be free of design features that give rise to concentrations of heat. The aircraft design must be able to spread the heat over the surface of the structure. Thermal management is critical to high-speed aircraft, especially hypersonic vehicles. Skin friction releases heat energy into the aircraft and must be pumped out again if the vehicle is to have any endurance. The only way to do this is to heat the fuel before it enters the engine, and dump the heat through the exhaust. On a hypersonic vehicle, thermal management is very critical, the cooling capacity of the fuel must be used carefully and efficiently or else the range and endurance of the aircraft will be limited by heating rather than the actual fuel tank capacity. So how will an aircraft reach such speeds? Conventional turbojet engines won't be able to handle the incoming airstreams at such speeds, they can barely handle transonic speeds. In the case of hypersonic propulsion, an aero-thermodynamic duct, or ramjet, is the only engine proven to work efficiently at such speeds. Even ramjets have drawbacks though, such as drag created in the process of slowing down and compressing a Mach 6 airstream. To make a ramjet engine efficient is to spread the air over the entire length of the body. In a hypersonic ramjet aircraft, the entire underside of the forward body acts as a ramp that compresses the air, and the entire underside of the tail is an exhaust nozzle. So much air underneath the aircraft serves another purpose, it keeps the plane up. The ramjets need a large inlet area to provide the high thrust needed for Mach 6 cruise. As a result, the engines occupy a large area beneath vehicle and the need to accomodate a large quantity of fuel means that an all-body shape is most feasible. Structurally, the all-body shape is highly efficient. As well as being extremely aerodynamic, the average cross-sectional area being very large provides a great deal of space for load, equipment and fuel. This being inside a structure that is light and compact having a relatively small surface area to generate frictional drag. The spyplane's airframe may incorporate stealth technology, but it doesn't really require it should its mission simply involve high altitude reconnaissance. Hypersonic aircraft are much harder to shoot down than a ballistic missile. Although a hypersonic plane isn't very maneuverable, its velocity is such that even a small turn puts it miles away from a SAM's projected interception point. . Choosing The Right Fuel Choosing the right type of fuel is crucial to the success of Aurora. Because various sections of the craft will reach cruising-speed temperatures ranging from 1,000 degrees fahrenheit to more than 1,400 degrees fahrenheit, its fuel must both provide energy for the engines and act as a structural coolant extracting destructive heat from the plane's surface. At hypersonic speeds, even exotic kerosene such as the special high-flashpoint JP-7 fuel used by the SR-71 Blackbird can't absorb enough heat. The plausible solution is cryogenic fuel. The best possibilities are methane and hydrogen. Liquid hydrogen provides more than three times as much energy and absorbs six times more heat per pound than any other fuel. The downfall is its low density, which means larger fuel tanks, a larger airframe and more drag. While liquid hydrogen is the fuel of choice for spacelaunch vehicles that accelerate quickly out of the atmosphere, studies have shown that liquid methane is better for an aircraft cruising at Mach 5 to Mach 7. Methane is widely available, provides more energy than jet fuels, and can absorb five times as much heat as kerosene. Compared with liquid hydrogen, it is three times denser and easier to handle. Current Knowledge of Aurora On 16 November 1998, a camcorder video was taken of a mysterious "fireball" in the sky. While this was very interesting, what was even more amazing was the aircraft which was seen shortly after flying at very high speed producing the mysterious "donuts-on-a-rope" contrails. Does this video, which is currently undergoing intense study at JPL, show the mysterious Aurora spyplane? A newspaper article about this event was also written in the The Sun Herald newspaper.

you know what would be funny if the aurora really dosent exist.

This plane exists! The technology exists and it’s been about for a while and this plane has existed for a number of years. The existence of this plane was even leaked by an American general in a press conference a few years a go. It was spotted in the North Sea because the American military uses the British air strips in Scotland because of the remoteness of the area. There are probably now planes the American military have developed that are even faster than the Aurora. THIS PLANE EXISTS!

It is my considered belief that the "Aurora" aircraft does not exist. It really comes down to a lot of wishful thinking by aircraft enthusiasts.

What on earht was it doing in the North Sea? Is it like the flying subs from 'Voyage To The Bottom of The Sea'?


Couldn't resist that one. Not that I tried very hard

Me too, the 'legends' have been dragging on for far too long, stuff like the Blackbird and F-117 etc remained secret for a few years but this has been going on for 25 now. Also, why the experimental hypersonic research vehicles at huge expense?

For Aurora, read Fairies at the bottom of the garden, or even Fairey's if you like

Spy planes are pretty much obsolete now that there are spy satellites. A hypersonic bomber might make more sense.

Look belive me it exists! I can understand they would build it now but this was developed and built during the cold war. When it didn't matter what the cost was but all that mattered was the advantage over the Soviet union was in favour of America. Now they don't need it because of the war on terrorism. BUT IT DOES EXIST!

machtistle, I will tell you, what you'll get from all your critics. Until you can put forth solid un-disagreeable evidence pertaining to the existence of the Aurora, we will always remain skeptical.

So saying "Believe me, it exists" is not the way to approach this board.

Now, at some time it MIGHT have existed, but as to whether it exists now, I highly doubt it. As one head engineer from Lockheed said, the Aurora at some point did exist, but not anymore.

Shattered OUT...

Just wait, in time this plane will be showen to the world. Look they were able to keep the U2 secret for a while untill it crashed. They kept the f117 secret as well and the B2 too. Belive what you want but this exists.

Spy planes will NEVER be obsolete. One of the things they learned shortly after the SR-71 went away was that it's actually a lot harder to get intel with a sattelite because they're predictable and tracked, so whoever you're looking at knows just when it's coming overhead.

As far as the secrecy, as Waynos said, the SR, U-2, F-117, B-2 were all kept secret for a FEW years, not 25 or more. There should have been SOME kind of leak by now. As a quote I heard once said "The only way two people can keep a secret is if one of them is dead." How much more for the designers, builders, maintenance guys, pilots, etc.

macthistle, as shatteredskys said you will not get anywhere just saying believe me it exists as you are not giving any proof, give links to sites with these first person accounts. And to be honest how can you be so sure? Do you work in the military or have you just been swept along with all the other aurora fans with the hype?

The aurora label has been plastered across every new technology the USAF have released and every blurry picture taken ever since the 1986 budget. Yet no clear photos have ever been seen and aviation magazines have been publishing the same articles and computer rendered images for so long that many people including me believe that aurora will never be released as its the perfect cover for any secret tech. Anything thats ever spotted is called aurora and is drowned in all the other information that has been collected over the past 20 years!

Just my two cents

PROOF... That is your opinion... but without proof, the plane doens't exist...

Its been flying for about 25ish years now, Well since the 1980s.

If it gets revealed to the public, everyone would think it s totally brand new!

Imagine if someone managed to steal the Aurora and flew it slowly over a city to reveal the plane or if he sold it to a foreign government?

Would he be rich, famous or dead?

Why should we beleive you? Upon what evidence?

Now they don't need it because of the war on terrorism.

Then why don't they reveal it? It would certainly make the public think that those black budget operations are worth it, and if you were able to confirm that it exists, surely russia, china, iran, other nations, have been able to, so there's no secret advantage to not discussing it. I mean, if they told people about the invisible planes, and the invisible robotic missiles, then why hide a hypersonic spyplane?

Can anyone tell me if the then extant TEAL RAIN program (led ultimately to the Predator, was a "black" project from 1980 to 1988) was declared in the 1985 budget - or the ATB fly-off? These are both examples of projects "Aurora" could have referred to in the 1985 budget.

I think its entirely possible that aurora referred to something entirely different from what it has now come to mean. The FAS have loads of information on Aurora:
www.fas.org...
About half way down the page there is plenty of information on the budgets in which it appeared and underneath what it could refer to.

I dont know what Browno is trying to put across but he hasnt shown any proof or even evidence that Aurora exists. Also I cant see how it can have been flying for 25 years when funding of $80 million (indicating aircraft development) was requested in 1985.

I still believe that Aurora doesnt exist and has simply become a catch-all term for black-project researchers, a composite of every project the USAF has been pursueing over the past 20 years resulting in just confusion where everyone believes aurora to be a different thing.

The aurora is the best coverup made in years. Everyone is looking at the aurora and have been looking for almost 15 years now, since they slipped that word in the budget of 1988.

If we look at the facts and see how the US is more or less 20 years ahead of what their public display if technology (check the development dates for have blue and the ATB to name just 2), its very reasonable to expect they have made huge advancements over time.

On the other hand, for every project there are tenths of projects cancellations for money, failed technology, you name it. Aurora might be a study, a concept or just a project that went down and they don't reveal it because probably AlQaeda is not affected by the existence of radical technology like the USSR was.
