My wife bought this for me for my birthday, and though I am only a few pages in I can already share with you this amazing gem: Did you know the He 219 at the Hazy-Udvar is a 3 seater? Me neither. There is actually a crude jump seat in the rear fuselage accessible from a hatch on the bottom of the aircraft. There is even a plexiglass window above it, cut through the top of the fuselage! Who knew?
