Top pic is amazing. I see it contains a P-38, P-39, and I believe that's a P-51 under the left wheel door of the 88. I can't really make out the others in the background.
Same plane on the bottom pic has a B-25 and a B-26 in it.
Good spotting on the background, thorlifter. The concrete runway and buildings in the background make me wonder if this may have been a state-side airfield for comparative testing of captured aircraft. I've always thought most of the fields in England/Europe used by the USAAF had a more temporary look to them.
also spotted a P-40
