Thanks, all4one. I wonder, if they're describing the "mortar" shell as six feet tall, don't they mean one of the shells for the 16" guns? This sounds more like a prank, since they'd have to know it was a dummy round, and there's no way to fire that thing without a honkin' big barrel.
I worry more about the fact that these clowns got access to the Mo' without anyone stopping them.
Mo' = Wisky
memo: do not FReep and eat soup at the same time.
I was thinking prank as well...but these days...four people...dress all in black...wandering around on a military ship before dawn...
