Merci beaucoup, Laurent, and that's what I would have suggested, a daylight operation, so other aircraft, especially those nearby, taking off at around the same time, may well have recorded attacks.
Additionally, after the War, the bodies were reburied, so perhaps the CWGC have the initial burial site in their records. Can't hurt to email and ask if they have anything on the original crash site, or where that info might be found.
