Aurora Top Secret Spy Plane SR-91 | This Plane Doesn't Exist


Aurora was a supposed American reconnaissance aircraft from the middle of the 1980s. It has been labeled a myth since there isn't any solid proof that it has ever been constructed or flown.

The American administration has consistently denied ever building such an aircraft. The aviation and space reference site Aerospaceweb.org came to the following conclusion: "There is little reason to question the government's view; the evidence supporting the Aurora is circumstantial or pure supposition."

The US was left without a new surveillance plane to fly across the world after the SR-71 spy plane program ended in the 1990s. Since the SR72 is still decades away, it is assumed that the military has been flying blind for the past 30 years. There have been numerous reports of strange triangle aircraft flying over military airfields all over the world.

Although not much is known about this aircraft, it is thought to cruise at a height of roughly 90,000 feet and reach a top altitude of 135,000 feet (or potentially 110,000 feet). The plane would be flying at extraordinary speeds, easily pushing Mach 6, and blasting across the sky at these altitudes.

It would need either a ramjet or an early scam jet, like the one proposed for the SR72, or a highly loud propulsion system termed a pulse wave detonation engine to travel at this speed. It is extremely dissimilar from conventional engines. The deflagration of fuel, which is the quick but subsonic combustion of fuel, is the basis for all conventional jet engines and the majority of rocket engines. The supersonic detonation of fuel powers the pulse detonation engine.

If the aircraft possessed this engine, it would let it fly over any existing anti-aircraft defenses and have a range significantly larger than the SR-71, whose employment necessitated a sizable tanker support fleet. Spying would be the mission profile of the Aurora, which would be used to fill the gap between spy satellites and slower aircraft or drones.
