Yeah it sums up rather sad feelings for me does the Wimpy, it was pretty much out classed by the German fighters, and lacked adequate defences really, but speed was on its side compared to other bombers at the time. Its geodectic structure was quite revolutionary and ment it could take a lot of punishment.
It began taking the fight to the axis in 1940 and didnt stop until 1945 even though it was again outclassed by its younger sisters such as the lanc, and was more expensive to produce because of the structure design.
They very often at the time in 1940 went out alone at night, I was stationed for a short while at RAF Honnington, they used to have Wimpy's there untill the base was lent to the USAF, and in stories I have read about the wimpy's from that base the often had these smaller type raids nightly as well as the larger ones, but even in these larger raids there was no formation type of flying (tatics used by bomber command untill the end of the war) they took off one by one and made their own way to the target and back again. Lonely and scary stuff I would imagine.

Sadly Wellington crews took the heaviest toll of all the Bomber aircraft crews, and most of the crash sites of RAF bombers here in the UK were Wellingtons, but no other bomber served for the whole duration of the war in the role or way the wellington did, it wouldnt suprise me that the Wellington being the first bomber to drop ordinance on Berlin, maybe was the last bomber to do so as well.
And they did all this at night and alone.
What a plane.
