I was looking for more on 604 and came across this from one of the recovery team.
............... 604 cleared the end of the runway and went into a left hand turn to go around the circuit. Number two engine shaft broke so the compresser blades acting as a gaint saw went through the bomb bay cutting all the controls and hydraulics. The Vulcan crashed in the front yard of a local farm. When we went to recover the pieces........... as we where digging in the hole we found the entrance door of a B17 which had crashed in 1944. We also came across some other unidentified material. When we asked the farmer what he knew he told us the Vulcan was the fourth aircraft to crash in that spot.
