In answer to TA152s question

I've taken the tour of Universal Studios and saw the 73. The guy giving the tour laughed when he said that (the little pond it was sitting in) this was the only water McHails Navy ever saw.
Something else from that show..."Washing-machine Charlie"
Originally from Europe as a way to identify German planes (I'm told)(Erich could tell you more).
Germans didn't bother to synchronize motors on multi-engined (mostly 2s) planes like the Allies did. A waste of unnessary polish/time in war-time, So a Whroom-Whroom-Whroom would be heard (as you heard each engine at "close but not the same" rpm, instead of a steady roar.
Hence the nic-name.
