"I remember one morning a British Halifax coming back from Italy landed by mistake on our airfiled [Théville, Normandy, France]. The crew was surprised when seeing german soldiers and more when looking at victory bars on Schnell's plane rudder. These airmen (...) belong to N°35Sq who made an important attack on Torino. (...). F/O Williams lands his machine (...) in ennemy territory. So JG 2 is able to capture seven airmen and to give a Halifax in perfect state to Rechlin test center. Three Wellingtons are lost this 10 to 11 September [1941] night and the famous Halifax TL-R intact is the only 4-engines plane not to go back in England"

I find that the only missing aircraft was L9566, described as crashlanded in France, navigational error. Given all that has been published on the Rechlin trials of Allied aircraft, I find the suggestion that there was a Halifax there as well somewhat surprising.
