This show looks into lingering rumors that advanced military aircraft,
such as the SR-71 Blackbird and B-2 Spirit Bomber, were designed from
reverse engineered alien technology.
Reverse engineering
Attempts
have been made to reverse engineer the possible physics behind UFOs
through analysis of both eyewitness reports and the physical evidence,
on the assumption that they are powered vehicles. Examples are former
NASA and nuclear engineer James McCampbell in his book Ufology,
NACA/NASA engineer Paul R. Hill in his book Unconventional Flying
Objects, and German rocketry pioneer Hermann Oberth. Among subjects
tackled by McCampbell, Hill, and Oberth was the question of how UFOs can
fly at supersonic speeds without creating a sonic boom. McCampbell's
proposed solution is microwave plasma parting the air in front of the
craft. In contrast, Hill and Oberth believed UFOs utilize an
as-yet-unknown anti-gravity field to accomplish the same thing as well
as provide propulsion and protection of occupants from the effects of
high acceleration.
UFOs are sometimes an element of conspiracy
theories in which governments are allegedly intentionally "covering up"
the existence of aliens by removing physical evidence of their presence,
or even collaborating with extraterrestrial beings. There are many
versions of this story; some are exclusive, while others overlap with
various other conspiracy theories.
In the U.S., an opinion poll
conducted in 1997 suggested that 80% of Americans believed the U.S.
government was withholding such information. Various notables have also
expressed such views. Some examples are astronauts Gordon Cooper and
Edgar Mitchell, Senator Barry Goldwater, Vice Admiral Roscoe H.
Hillenkoetter (the first CIA director), Lord Hill-Norton (former British
Chief of Defense Staff and NATO head), the 1999 French COMETA study by
various French generals and aerospace experts, and Yves Sillard (former
director of CNES, new director of French UFO research organization
GEIPAN).
It has also been suggested by a few paranormal authors
that all or most human technology and culture is based on
extraterrestrial contact.
