The BCL entry indicates that Lancasters DS669 and DS828 of 514 squadron 'MAY HAVE' collided over the target on the 22/4/44. Clearly at some time or another some evidence existed to come to a possible conclusion of the collision and I wonder if the fact that the Pilot and Wireless Operators bodies in DS828 were never traced provides anything further to corroborate the supposition.I am assuming both men would have been in the forward positions and in close proximity to each other.
