Explosions go BOOM! so…implosions would go MOOB! but… I would think it probably sounded more like MOOP!
Maybe the Navy would release the tape…like it matters.
RIP.
From what I’ve read years ago, the IM-plosion is followed immediately by an EX-plosion.
The air and and any flammables inside the ‘container’ are suddenly compressed just like the air-fuel mixture in a diesel engine cylinder, and it ignites under compression.
So it would be like a CRUNCH!-BOOM!..............
