This was was good. I fully concur with your comments on Grissom's calm and professional demeanor. One question, he talks about having trouble getting a door pins inserted. Could this been a causal factor on the hatch blowing prematurely? BTW, if NASA believed Gus was at fault, he would not have been given command of the fist manned Gemeni mission and been named to be the commander of the first manned Apollo mission.
