Re:26 May 43-Pilot Loss 317FS
I actually have that incident dated as the 27th of May, after a sortie to escort bombers to Decimomannu.
It reports the pilot was Lt Bill Hemphill who had to ditch in the sea. Flight Officer Dick Catlin circled him and dropped a life raft, while reporting his position to Air Sea Rescue.
Hemphill managed to board the raft and an RAF Walrus landed to pick him up. The Walrus however crashed on take-off, sinking almost immediately with the loss of all onboard.
Hope that helps, cheers, MP.
