My grandfather flew a B-24 in WWII based out of England, completed all his missions. Instead of returning home he stood up to fly supply runs for awhile. I think it was fuel. We still have his log book among a few other things. Seeing the many bombing runs over Berlin and other targets deep in enemy territory is humbling. I never did get to hear him talk about his experience, I don't think I was yet 10 when he passed.
This year on Dec. 7 I was on USS New Jersey (BB62) with my scout pack. We spent the night, toured the ship, learned an awful lot. In the morning as part of the ceremonies that day they fired a powder charge from one of the 5" guns. Our boys sure got some experience, I hope they remember and understand it.
