UFO or IFO? The U.S. Miltary’s Flying Saucer for #UFODay:
This Identified Flying Object is the U.S. Military’s “Avrocar,” an experimental flying saucer conceived in the 1950s. The Avrocar was initially intended to be a vertical take-off and landing (VTOL) aircraft that could travel at speeds of up to Mach 4. During the Cold War, traditional airport runways were seen as easy targets for an attack. With a fleet of VTOL aircraft, the United States could build underground airports, protected from Soviet bombers. The Avrocar would ascend through a shaft and then zip away at supersonic speeds.
The Avrocar’s disc shape and ability to hover bring to mind the flying saucers that we associate with extraterrestrial sources, but the project never really got off the ground–both figuratively and literally.
