Can anyone tell me if there was any set formation pattern for B-29s when flying over Japan or enemy territory in general? I am certain 20th AAF procedure differed from that of the tight combat box formations flown by '17s and '24s in the ETO.

I am sure I have read they flew in loose formations and only closed in when near or over the target areas, or perhaps where enemy aircraft were expected, and that after hitting their targets, flew home in no particular order and sometimes alone?

Thank you
