I discussed the history of the Avro Lancaster 4 engined heavy bomber in general, and this one in particular, in image 30322.

Here we are looking forward from the aircraft's tail, seeing the rear part of the fuselage and the trailing edge of the wing. Also visible is the dorsal gun turret.

Looking at this big slab of space you may think that the Lancaster was a spacious and comfortable aircraft to fly in. Well, except for the Luftwaffe and ground based anti-aircraft guns shooting at you, of course, that could make for an unpleasant ride and all respect to those who knew that and did it anyway.

However the truth is that it was relatively cramped, it could get incredibly cold, and the noise and the vibrations of the engines made even a Qantas Boing 737 cattle class flight seem luxurious in comparison.

Unfortunately you can't go inside this one (for good reason, especially considering that there are only 17 in tact Lancasters left in the world), though there is an interactive exhibit at the Australian War Museum in Canberra which gives something of a flavour of the conditions inside a Lancaster in flight. (Not the cold and claustrophobia, but the noise and vibration at least.)

Addendum: My personal opinion is that Facebook is a sociopathic organisation that steals other peoples' intellectual property (including the images in this gallery) despite being explicitly denied permission to do so.
