Alleged to have taken place at Bentwaters in Dec 1980 at the same time as the Rendlesham Forest sighting:
HH: October 2000
HH was stationed at the 81st Security Police Squadron at RAF Bentwaters in England during the UFO events that occurred in December 1980. She and a colleague were on duty late that night, when they saw in the distance an object they thought was a plane landing on the runway—coming in from the direction of the North Sea. They also saw it silently explode, split into three parts, and speed across the runway; then it went straight up and disappeared.
