[Andrei Demjanko]

Aircraft force-landed not always means 'aircraft crash-landed' on return to base or elswere. It also means that aircraft not returned to the aerodrome, which was the unit's base, and landed on another airfield due to fuel situation, weather, battle damage, whatewer reason.

Speaking of 18 December 1939 I have data only for 9 Sqn. Of nine aircraft from this unit participating, only two returned to base at Honington. Five aircraft of the unit were lost in this operation. Two of their Wellingtons were damaged in aerial combat, one landed on return at North Coates and another landed at Sutton Bridge, the latter aircraft with two wounded crewmen aboard. These two aircraft are certainly amongst those, mentioned by Shores and Prien
