ISTR that the US air Force wanted a B17 only bomber force in Europe?
In August 44 the decision to build up the B-17 force in preference to the B-24 lead to two bomb groups to convert from the B-24 to the B-17. Aircrew were generally enthusiastic about the B-17 with its better handling, more spacious nose compartment and better heating.
I would go along with B17....because (allegedly) it was akin to flying a 4 engine Cub
Probably because its wing loading was 30% less than the B-24..
