The videos above show two very different ejection outcomes. Dave in 885 is the first, and his seat fires and launches him quite a way up. His parachute subsequently snagged on the sinking aircraft, and he was dragged under, but he managed to get clear and popped to the surface. After we lost the A-4s he joined the Royal Navy, and had a career flying the Sea Harrier, eventually gaining command of one of their squadrons. As a sideline he also flew for the RN Historic Flight, and so has time in the Swordfish.
The second video actually happened years earlier, and shows a failed ejection. The canopy fires, but the seat doesn’t, so he rode it into the water. He got clear after the ship had passed overhead. He eventually became a Cathay 747 pilot.
