I hadn't seen these before hopefully they haven't been posted before. KTK http://www.alternatewars.com/Bomb_Loading/Bomb_Guide.htm
Extraordinary pics. I have never seen them before. The chronology brings the pics to life. Good find. The courage of those engineers rigging the bomb.
so fat man was much bigger than little boy. i'm curious about those "thin man" tubes. they're the actual "guns" that will drive a uranium projectile into the center of a uranium sphere? in the picture, it said plutonium, which i don't think is possible.
