Beating Gravity - Aurora
1985, a budgetary weapons procurement document made reference to a top secret
multi-billion dollar USAF program called Aurora. Looking into this document,
the Washington Post learned unofficially that it was linked to stealth technology,
possibly development of the B-2 bomber project. Three years later, the New York
Times reported that a hypersonic reconnaissance aircraft with stealth capability
was being developed to replace the SR-71 Blackbird.
Unconfirmed reports of Aurora's existence first surfaced in 1986. Popular
Science magazine conjectured about the airplane's likely design in its November
1988 issue (right, middle).
Sounds: Most of the evidence for Aurora's existence is anecdotal. Among
these tales are the reports of unusual sonic booms above Southern California,
dating back to mid and late 1991. On at least five occasions, the booms were recorded
by at least 25 of the 220 US Geological Survey sensors across Southern California
used to pinpoint earthquake epicenters.
Seismologists estimate that the aircraft were flying at speeds between Mach 3
and 4 and at altitudes of 8 to 10 kilometers. The aircraft's flight path was in
a north north-east direction, consistent with flight paths to secret test ranges
in Nevada. Seismologists say that the sonic booms were characteristic of a smaller
vehicle than the 37-metre long shuttle orbiter. Neither the shuttle nor NASA's
single SR-71B were operating on the days the booms were registered.
Intercepted radio transmissions add further circumstancial evidence. Radio hobbyists
in Southern California have monitored transmissions between Edwards AFB radar
control and a high-altitude aircraft using the call sign "Gaspipe."
Controllers were directing the Gaspipe aircraft to a runway at Edwards, using
advisories similar to those given space shuttle crews during a landing approach.
The monitors recorded two advisories, both transmitted from Edwards to Gaspipe:
"You're at 67,000, 81 miles out" and "Seventy miles out, 36,000,
above glide slope."
Sightings of unidentified high-performance aircraft have been made in the Southwestern
United States and, later, in other parts of the United States and in Britain and
Europe. Reports from outside the United States are difficult to reconcile with
an experimental test program, and make more sense in context of the deployment
of an operational aircraft.
In addition to reports of triangular high-performance aircraft, numerous reports
mention peculiar contrails consisting of a string of pulses or rings, often referred
to as a "string (or chain) of doughnuts".
Chris Gibson (sometimes incorrectly named in sources as Chris Hudson), 30, was
in the Royal Observer Corps aircraft recognition team for 12 years up until 1991.
Chris told Jane's Defense Weekly that while working as an oil-drilling engineer
in the North Sea in 1989 he saw a strange wedge-shaped aircraft flying between
two conventional F-111 fighter-bombers and a KC-135 Stratotanker.
simulated depiction often captioned as of Aurora refuelling under F-111
escort has been widely circulated. This illustration is a photomontage which was
created by Bill Rose, to illustrate an article in a 1995 issue of the U.K magazine
Astronomy Now by Bill. It was never intended to be an accurate portrayal
of Chris Gibson's sighting. A second, better image was used in an article by Rose
for UFO Magazine. A third version, which almost perfectly depicts the sighting
according to Chris Gibson, can be seen in Tim Matthews book UFO Revelations
and several U.K. magazines.
Gibson's report is widely considered to be one of the most reputable sighting
reports of what is thought by many to be the Aurora, or at least some other
"black" aircraft. It is worth commenting that Chris himself does not
claim to have seen Aurora and, befitting a witness of his observer background,
would not leap to such a conclusion in the absence of solid information.
The picture gained some cult notoriety when published in the British magazine
UFO Encounters which put it on its February 1996 cover with the caption
"UFO Escort Picture: We Unveil New Evidence Of This US Cover-Up". Other
UFO magazines reacted more calmly and clearly identified the image as a simulation.
The renowned aviation source, Jane's Defense Weekly, has added its reputable
weight to speculation about Aurora by alleging that the triangular shaped
planes have been in service since 1989, after they had analysed information to
hand for about three years. Jane's editor, Paul Beaver, has said "The
evidence has grown overwhelming - all we need now is a photograph to prove that
Jane's analysts believe that the $1 billion aircraft which has now been
dubbed Aurora could reach cruising speeds as great as Mach 8 - or 5,280
mph, which was more than 2½ times the official world record. Jane's
technical editor, Bill Sweetman, reported that the so-called "hypersonic"
Aurora operates mainly at night and incorporates the latest radar-evading
The Pentagon announced in 1990 that it was retiring its supersonic spy plane,
the SR-7l Blackbird, and would rely for its future
high-altitude surveillance on orbiting satellites. Sweetman, an expert in high-technology
aircraft, maintained the Pentagon story about satellite spying was a smokescreen.
A Mach-8 plane would be able to reach any point on the globe in less than three
hours. Such a plane, fueled by liquid methane, would be of potentially greater
use than high-resolution images from orbiting satellites that can take 24 hours
to arrive over the subject, the Jane's report said.
Sweetman based his conclusions on pieced-together data, including the strange
sounds reported above air bases in Nevada and California that were characterized
as a "low-frequency, high-amplitude pulsing", multibillion dollar spending
on classified research projects and the Gibson sighting of a wedge-shaped aircraft
over the North Sea under fighter-bomber escort.
Sweetman believed the U.S. aerospace giant Lockheed, which produced the F-117
stealth fighter, is the most likely manufacturer of Aurora. "Lockheed's
financial figures have indicated a continuing, large flow of income for 'classified'
and 'special mission' aircraft," Sweetman reported.
Among the varied claims relating to Aurora are:
- Aurora is considered to be hypersonic, about 30-40 metres long, with
a 75 degree dart shape and weight of around 70-80 tonnes, with a crew of two.
- Its primary purpose is long-range reconnaissance, with an unrefuelled range
of at least 10,000 km.
- As a weapons platform, it may have potential for surgical nuclear strike or
- It may be trans-atmospheric, or have a trans-atmospheric variant.
- Power plants may be pulsed detonation wave engines (theoretically capable of
powering an aircraft towards Mach 10 at over 180,000 feet altitude). These engines
have been studied since at least 1993. Laser detonation is posited as a means
of maintaining precise control over ignition, which may occur externally, or,
more conventionally, in a confined chamber. Alternatively, Aurora may use
a combined cyclic engine. The latter could function as an air augmented rocket,
a ramjet, a scramjet
and a rocket. Methane could serve as fuel, or liquid or slush hydrogen, doubling
as a structural coolant. Either power plant is possibly capable of producing the
unusual doughnut-chain contrails reported in recent years.
- A small squadron of Auroras is rumoured to operate from Beale AFB, in
- Aurora may have a coating which can be made to change colours, or even
render it invisible(!).
- And finally, the Northrop B-2 stealth bomber is seen by some as an expensive
($22.5 billion development costs) cover-up for development of Aurora, on
the basis of suppositions concerning range, speed, stealth and payload disappointments
in the production B-2s.
