According to the thread given by Marc, Schäfer - if that Schäfer - didn't claim any Lancaster that night ... But the mission starting the day and ending the following day ...
Regards, Franck.
Correction: The mission started on 21/06 at 23:17. Effectively LM508 was lost on 22/06. Don't understand why lostaircraft.com retained 21/06 for the lost date.
