I hear that the R - A - T (I'm manx and superstitous
) is seriously noisey when it's deployed.
There was an incident, sorry donno specifics, when an airbus A320 with a dodgey engine had to deploy it. The flight crew where so busy trying to sort the problem that they forget to warn the cabin crew! Apparently they all thought they were going down and that the flight crew where incapacitated....
sphincters finally relaxed when the captain came through on the intercom
