Foreman states that KG 1 bombed London that night (19/20.3.41).
Another I./KG 1 Heinkel also crashed at Amiens the same night on its return, WNr 5643, although only 35% damaged. I find it quite possible also "our" aircraft took part in that raid. However if it was damaged over England or simply crashed due to a pilot error is more difficult to say....
The odd thing is that Foreman doesn't mention WNr 5622 at all....
