re: #27 HoosierHoops
We used only the highest quality of materials to build Nuclear Subs.
Even a bolt was made from exotic materials and were extensive tested.
So a 20 dollar bolt was well worth it.
Considering the pressures those things were under at their design depth, I begrudge them nothing. I liked my land based M-60A3 steel coffin much better. I hated the thought of burning to death, but that was still better than insta-squish if the pressure hull gave way. Shudder.
