Nice puzzle picture too
I found myself mostly distracted at all the aerodynamic goodness going on in the background.
I can make out:
B-29 (obvs)
Grob G102 (also obvious)
TG-1 (airforce training glider, blue with yellow wing, hanging center pic)
Hawker Hurricane (below the tail of the B-29)
Sopwith Camel (just aft behind the tail of the B-29)
Westland Lysander (hanging, below the G102)
Northrop flying wing (Yellow, left of the console)
Cessna 172? (center left, red tail, white Cessna text on the tail)
The rest eludes me.
A quick google also showed me what the Japanese aircraft at the bottom are:
Nakajima J1N1-S Gekko
Aichi M6A1 Seiran
Nakajima Kikka (loosely speaking a Japanese interpretation of the Me-262)
