Tip o’ the hat to the ingenuity and sheer guts it takes to build your submarine out of a couple of oil barrels and then try it out yourself.
I served on submarines for almost a decade, so i have some respect for what it takes to make those pig boats work. I’ll stick to the 688s over the oil barrel any day.
BTW, in other submarine news – Christopher Fitzgerald died today. Who’s he? He’s the CIA agent that worked with Howard Hughes’ team to secretly raise the sunken Soviet sub K-129 off the Pacific Ocean in 1968. It was referred to as Project Jennifer, it’s a fascinating story, read about it on Wikipedia.
