I am continuing this:
The distinctive "doughnuts on a rope" contrail and pulsing sounds reported by many have given rise to the speculation that the aircraft might use
pulse detonation propulsion technology originally patented in the 1950s, but not used on any acknowledged non-research project.
In addition to providing the first photographs of the distinctive contrail previously reported by many, the significance of this sighting was enhanced
by Douglas' reports of intercepts of radio transmissions:
“Air-to-air communications... were between an AWACS aircraft with the call sign "Dragnet 51" from Tinker AFB, Okla., and two unknown aircraft
using the call signs 'Darkstar November' and 'Darkstar Mike.' Messages consisted of phonetically transmitted alphanumerics. It is not known
whether this radio traffic had any association with the "pulser" that had just flown over Amarillo. ”
A month later, radio enthusiasts in California monitoring Edwards AFB Radar (callsign "Joshua Control") heard early morning radio transmissions
between Joshua and a high flying aircraft using the callsign "Gaspipe" (which could be a reference to the Aurora's supposed exotic propulsion
system[original research?]). Joshua controllers were vectoring Gaspipe into Edwards AFB, using terminology usually used during Space Shuttle
recoveries.[citation needed]
“You're at 67,000 ft, 81 miles out" was heard, followed by "seventy miles out now, 36,000 ft, above glideslope.”
At the time, NASA was operating both the SR-71 and the U2-R from Edwards, but it has been confirmed that neither of these types were operating at the
time Gaspipe was heard.[12] Curtis Peebles claims in his book Dark Eagles that the intercepted radio transmissions were probably a prank on the part
of Edwards security personnel, but it is unlikely that they would have access to the terminology used in the transmissions.
The Scottish connection
Beginning in 1991, reports started appearing in Scottish newspapers — including The Scotsman — that the Aurora was landing and taking off from
Machrihanish airbase on the Kintyre peninsula. Machrihanish was an RAF base with a long runway which was a V bomber dispersal base during the Cold War
before being handed over to the U.S. Navy, which used it as an overseas base for their Navy SEALs until 1995. It was alleged that air traffic
controllers had seen aircraft on their radars taking off from there and accelerating to high Mach numbers. None of the supposed controllers has ever
gone on the record. Others have claimed that Royal Marines inadvertently discovered the Aurora in a hangar at Machrihanish, but again none of the
supposed witnesses have ever gone on the record.
Other sightings
* In 1998, another aircraft spotter videotaped two unusual contrails in quick succession. One of the sights appeared to be a fireball, while the
other was described as "doughnuts on a rope."
* In March 2006, the History Channel broadcast a television program called "An Alien History of Planet Earth" which examined UFO reports in the
context of secret military aviation programs. During the program, aviation journalist Nick Cook presented a satellite image of the continental U.S.
showing a contrail allegedly originating in Nevada and extending over the Atlantic Ocean. The contrail was unusual, as it appeared different from
other contrails visible on satellite images. The craft that produced those contrails was not visible on the image. Based on the details of the image,
it was speculated that it indicated an aircraft flying at a speed of around 7,000 mph (Mach 10.5).
In the 1980s and 1990s, NASA and several aerospace companies proposed multiple aircraft designs for hypersonic aircraft that are reminiscent of the
aircraft described by Gibson.
