Farnborough, England: RAF Officers Observe Flat Disc at Air Display Preparations
On September 5, 1950, during Farnborough Air Display preparations, an RAF lieutenant and six officers observed a flat disc, light pearl gray, following a fast rectangular flight path with 'falling leaf' motion 10-15 miles distant.
Background
At 4:09 p.m. on September 5, 1950, while preparing for the annual Farnborough, England, Air Display, an RAF lieutenant was among six officers in the watchtower who caught sight of something unexpected some 10-15 miles distant. (The lieutenant had witnessed the same or an identical object three days earlier.) All described it as a flat disc, light pearl gray in color, its apparent size comparable to a shirt button at arm's length. It followed a fast, rectangular flight path in addition to a 'falling leaf' motion — upward as well as downward. Finally, it left for the horizon at great speed.
