No Lancaster is reported as having crashed that date, so may I ask what information you are after? Was someone you know on board?
Any information you already have may help us. As to who maybe on the aircraft on this particular flight, the place to look would be the squadron ORB (Operations Record Book), which you would need toseek through the National Archives. If you know the squadron then I could give you the relevant reference, and a couple of contacts who maybe able to get copies of the relevant page(s)...(TNA are basically refusing to copy pages to ORBs or charging outlandish amounts).
Depending on squadron, there maybe guys over on rafcommands who already have a copy of the ORB (though ost of us tend to only have them for the war years, some have expanded their collections).
