I'd be glad of caption information for any of these. For example, the lads in shorts and light khakis in the last photo--are they RAF?
I probably should say that I post these in reverse order of how they were received. I reckon first we get the posed shot of the lads getting their mission orders, then firing up the engines, then taking off, etc. The one at the top I suppose actually goes earlier in the sequence; probably it should be number two.
