So how's about a "ThicK FA Comments"
FA: so what does that do? (pointing to ADG)
Capt: it opens a little door and a little propeller comes out of the aircraft.
FA: well thats silly, what do you need a propellor for, this is a jet?
Capt [glancing sideways at me]: Well, its the "Automatic Ditiching Generator", if we have to ditch, we pull it when we are in the water and we can steer the plane to safety.
FA: oh that's so cool! a lot more planes should have them on!
bless! Jen was a bit of an airhead, but lovely with it !
