flying disk

'Flying disk' was an alternative description, commonly used between 1947 and 1952, for the phenomenon also known as flying saucers. It appears to have been the preferred term in military circles until it was superseded by 'unidentified flying object' at the start of Project Blue Book.


Alternatively, 'flying disk' was a popular description for the Avrocar experimental aircraft. Incidentally, there is no possibility that the Avrocar, despite its appearance, could have been responsible for any UFO reports, since it only flew at test sites and never at more than a couple of meters above the ground.
