Apologies for the late response. Specifically, I would like to view Fritz Kelb's record for the 10th of April 1945. At least one Halifax, and one Lancaster were brought down that day, albeit from what I recall, they were officially brought down by flak. Kelb would not have known this, but an aircraft he attacked, Lancaster ME315/LQ-K of 405 Squadron, had its rear turret blown off in his attack, and he presumably assumed he destroyed it. Unbeknownst to him, it was actually able to return home, albeit with great difficulty, and the loss of the rear gunner.
There seems to be conflicting data because of the descriptions given "According to one witness a Me 163 destroyed a Halifax, which "blew up right in front of me"".
I would like to know definitively which aircraft was destroyed, if any. It could be that flak genuinely brought down two aircraft, and the aircraft which "blew up" was ME315.
