Did You Know Certain Airbus Aircraft Have A 'Ditch Switch' For Emergency Landings?

Most famous recently is the US Airways incident in 2009, where an Airbus A320 aircraft successfully ditched in the Hudson River after dual engine failure on takeoff from La Guardia. In such situations, it is obviously important to make the aircraft as watertight as possible. Airbus aircraft have an automated function to help achieve this.
