The incident happened in 1976 near Bristol, UK.
Here the Witness recounts what happened at a meeting in 2010.
In 2010, as part of the Crop Circle Tour, we visited with some UFO witnesses in Wales in a meeting arranged by researcher Colin Andrews. We heard from a local woman who witnessed a glowing object over her car; an aerospace engineer who saw a disc over a tree in his backyard; and Ken, an RAF veteran and retired policeman, who saw a very bright UFO over a nearby golf course near Bristol in 1976 and then witnessed a robotic, 8-foot tall spaceman early the next morning.
