Rolling 20 / Load toad
I can agree with you both, as my Father was in Bomber Command at that time, before being shot down. He told me that due to the high loss rate being incurred by the RAF at the time Bomber Command could not expand with a two pilot strategy, hence the drop to one which occurred under Harris. As Load Toad says, maths and risk assessment at the time made the decision inevitable.
My Father thought an all Mosquito Bomber Command would have been safer for all concerned, as he only met one Mossie pilot when a Kregie as against many other's on the other 4 motor allied types.
