^^^ And some 20 years later, the USAF would do something similar to old C-47's, mounting a whole lot of guns on them and calling them Puff the Magic Dragon.....
These birds might just have been useful for ground support in WWII. Too bad nobody came up with that use for the modified planes back then.
I hate to say it but I just don’t think technology / comms were good enough in WWII. The few times they used heavy bombers as a sort of close air support (ex: during Cobra in Normandy) the results were either counter productive or produced a pile of friendly casualties.
