Paolo,
The Lancaster is not based at Duxford.
I believe its still based at RAF Conningsby , with the Spitfire & Hurry of The Memorial Flight.
Barnes Wallis , after seeing so few planes return from the raid , is said to have been deeply upset and expressed the wish , that he ' had never invented the damn thing ' .
My Father was in Gibson's original Squadron , namely 76th , but only joined months after he had left.
In my opinion , Bomber Command became an embarrassment towards the end of the war, in the eyes of Churchill. They were never properly recognised for their dangerous work. Indeed , percentage wise , they suffered heavier casualties than any other branch of the services .
To end on a lighter note.
Head of Bomber Command , 'Bomber' Harris , was known to drive his car around the country lanes at great speed , when returning home from his HQ. He is reputed to have been flagged down by a policeman on his bicycle . The policeman, upon recognising the driver said , ' Sir, if you continue to drive like that , late at night with blacked out headlights , you could easily end up killing someone
Harris replied, ' Kill someone !!?? , I kill thousands every night !!!
Here's a useful link to some of Barnes Wallis's other weapon inventions.
