In post #53 by ahwalk01, a link to a video of the lost aircraft is provided. At 45:26 into that video the passenger makes a passing reference to not having to use the Mk10 ejection seats as if they were still available for ejection at the time. But I didn't see any obvious ejection seat handles in the video. Can someone say with certainty whether or not the seats were still available for ejection on this aircraft? I realise ATSB will clarify this in a future report.
Unlike earlier seats like the Mk,4, the Mk.10 doesn’t have a face-blind handle, just one at the front of the seat pan. You can see this at around the 8 minute mark in the video. Totally unrelated to whether the seat’s still active, of course.
