Yep. Quick Disconnect is gone. I'm not surprised. It was of the wrong configuration for this area. But not to be deterred, I'll place a new cache here. The name, in and of itself, should give a clue as to where to look. As parents, have we not often told our kids to "pipe down," when we wanted the chatter to cease?
According to the Internet, "On sailing ships signals were given to the crew by sounding the boatswain's (bo'sun's) pipe. One such was 'piping down the hammocks' which was the signal to go below decks and retire for the night. When an officer wanted a sailor to be dismissed below he would have him 'piped down'. This usage is recorded in Royal Navy workbooks from the 18th century; for example, Gillespie's Advice to Commanders & Officers, 1798: "At four o'clock, P.M. the hammocks should regularly be piped down.
"There's no unequivocal link between this naval practice and the 'be quiet' meaning. It could well have derived from the fact that, if there was a disturbance onboard ship, officers could quell it by sending the crew below decks, that is, by piping them down. This notion is supported by records of ship's crew's being told to 'pipe down' rather than signaled to by the use of an actual pipe; for example, this report from The Gettysburg Star And Banner, April 1850."
