I was just watching on Sat TV a Deadly Engineering show about accidental explosions in past years. As I was listening to the list of past explosions, I notive there was no mention of the WW2 Pearl Harbor Explosion. The 2nd one the US tried to hide from Enemies during WW2. My boss in many yrs past was there at time ( Naval Officer) & told me about it. As I am remembering w/o looking it up on line, it was an amonition ship in harbor that exploded & destroyed the ship & many men! Dick Both, Retired NASA System Safety Engr, .
