Hello! First time posting here. I'm trying to find out more information about the accident involving Wellington MP575 on 06 Feb 1944, in which F/O Lawrence Andrew Arner (J/13745 RCAF) lost his life. I'm researching Lawrence on behalf of my father as we believe he is related to us. His service records state that he went from 407 squadron to 3 (C) OTU at the end of Nov 1943 but I gather that was then absorbed into 6 (C) OTU. I've managed to find ORBs (now that I've found out what those are!) for his time in 407 squadron, but not for either of those OTUs. Any information about the accident or in relation to his short time in those OTUs before his death would be gratefully received.
