Previously on this thread, I was struggling with the jump that had the seat unsafe for 4 days (and brought in all the missed chances), and as I suspected the investigators have gone from
1.4.2.18. ...most likely moved to an unsafe condition...
to
1.4.2.14. ...it was concluded...
But I can see that the boffins have done a thorough job before they 'concluded'. Not proven, but pretty compelling.
So if the boffins are to be believed without question:-
1.4.2.8. 60 Newtons? To fire the seat by pushing the handle forward. Is that broadly similar to a force of 60kg? 75% of his bodyweight? (I know about force and mass etc, but broadly speaking for the man in the street)
Lastly from me for the moment. If the seat was unsafe for 4 days, (unless I have missed it) the investigators have failed to document every event that happened between then and the accident. It seems to me that ejection seat pin checks up to this accident may have been a cursory glance, but I would therefore make a distinction of (an engineer) leaning into the cockpit to check something, or to actually sit in the seat.
