Tutor power hit glider near Oxford
The glider was hit from behind, it was flying in a straight line at the time, as recorded on its datalogger. The power pilot in the Tutor was flying aerobatics in a very busy area, near Didcot, and furthermore was unable to perform a good lookout because of a physical condition that prevented turning his head....
The glider pilot was able to escape by parachute. The RAF investigated very thoroughly and so did the AAIB, read the reports if you need more detail.
