Robert, thanks for the extra detail
Larry:
Yes, Lost Bombers follows the convention of naming
Pilot
2nd pilot or later, a Flight Engineer
Navigator
Bomb aimer /gunner (front)
Wireless/Radar Operator
Air Gunner (mid upper)
Air Gunner (rear)
for a typical 7 man heavy bomber.
For smaller crews, it just omits the positions missing
so a Blenheim would have
Pilot
Navigator
Gunner
for example
Some Lancasters carried an extra member of the crew for "special duties" usually a German speaker to broadcast false messages to nghtfighters to lure them away from the bomber stream.
Now, who's going to identify the Germans, and why one wears different boots to the rest? They look to have retrieved quite a bit of kit, parachute(s) leather briefcase, sheepskin jacket and poignantly one boot.
It looks as if the remnants of the rear turret are just visible.
