Didn't think you would be able to eject while still sitting on the ground.
They were airborne.
Many moons ago, ATC in the Marines. Slow as hell weekend day, we're sitting playing cards when we hear a whoosh sound and something goes flying by the windows. We run over and look, and in the ramp area in front of the tower there's a pair of Marines in coveralls running to pickup an ejection seat off the ramp, and an AV8B sans said seat.
