I was listening to a podcast where a Thunderbirds pilot was briefing his passenger and said that the command words for ejection would be "Bailout! Bailout! Bailout!".
Could it be as simple as establishing a common terminology that fits aircraft like the C-135, KC-10, C-130, C-17....etc as well as Fighters?
In the old days...while flying in C-119's....every passenger was fitted with a parachute and given enough instruction about its use to prepare them for an emergency exit of the aircraft.
These days that probably is no longer the policy.
I would suggest if you are sitting in an Ejection Seat....and the order to "Bailout" is heard....you might just be able to figure it out with just a bit of thinking particularly when it is a Command Controlled Ejection where the Rear Seater departs first followed by the Front Seater.
