I watched the Dambusters for the umpteenth time the other day. Something I noticed for the first time was the crew leaving a Lanc by a hatch on the underside near the front of the aircraft. Was this on the marks in service in wwii? AFAIK the only entrances/exits were the door rear right and the bomb aimers hatch.
The main spar was a PITA to negotiate and most aircrew don't fancy the humiliation to scramble over it. If the ground crew have a purpose made ladder to hand, then the front escape hatch (available since the first Manchester) would be preferred, for exiting at least. The ground crew, the rear gunner and maybe mid-upper would make more use of use the rear door.
Also, I think it looked more "rugged" for cinematic purposes to use the front. Makes coming back from an op less like stepping off the tube.
Thanks for that. I must admit I thought the only entrance was the rear door, and that the one in the nose was the bomb aimers window, never knew there was a hatch under the cockpit, you learn something new.
