Great start Peter, and the background information is very welcome, and has 'educated' me. Like many I suppose, I didn't know much about P39 operations in Europe/MTO, or the aircraft itself for that matter. It's a type that doesn't seem to have been fully recognised for it's contribution, possibly as it's reputation is a little clouded due to it's perceived failure for it's presumed role as a 'fighter'. I've only ever seen one in 'real life', and that was at a distance at an airshow years ago. I hadn't realised how big it actually is, especially it's height, until I saw your pics of 'Millie' on the ground, with her pilot. Impressive. BTW, don't know if it'll help, but I've found a cutaway drawing of the P39, which I can post, but it'll have to be in two parts, or photographed, as it's too big to fit my scanner.
