5 May 1969 – A USAF North American F-100D-70-NA Super Sabre, #56-3214, one of two Super Sabres from the 452nd TFS/81st TFW out of RAF Lakenheath, was on a gunnery mission over Holbeach Range, Cambs., UK. 
The plane suffered engine failure, forcing pilot Capt. R.E. Riggs to eject. The jet fighter impacted into farmland, missing a group of workers by 400 yards (370 m). The airframe was demolished in the explosion with only the fin and rudder assembly remaining intact.
