1.4.2.26 d "The panel concluded that the ability to initiate ejection in a manner different to the design intent was a contributory factor in the accident"
The fatal accident suffered by Steve Beckley with his Harrier at Yeovilton in the early 70's comes to mind.
P.S. ,Looking at Engine's thread regarding the MAA findings;
The MAA found that the CAUSE of the accident was the inadvertent ejection due to displacement of the seat pan handle.
Beckley wasn't strapped in his seat IIRC, but may have trodden on the seat pan handle.
