I have just finished drawing and scaling some larger US bombs which threw up an interesting question: The 4,000 lb one does not seem to fit in anything except the B-29 - was it actually used by the B-17 and B-24?
Just for example I took the measurements of the B-17 bay from a scale drawing as 2.5m long x 2.2m wide (which seems reasonable) but the 4,000 lb bomb is 2.9m long and 1.2m across the fins (I know this is right according to the official US Ordnance document)
So, I'm thinking either they were not used, or I screwed my scaling somewhere...?
