If there'd been an incident resulting from a need for the pilot to have two fully functional hands, that would have been more disturbing.
Isn't that exactly what this was? One hand remaining; control column or throttles?
Adding a pile of mechanical parts of unknown quality in the form of a prosthetic bolted to the yoke adds a whole new layer of failure possibilities
And also at a bottleneck with no redundancy. Yes, there WAS a second pilot but he wasn't used.
I was going to refrain from posting on this again but there is so much misrepresentation and lack of logic flying around that as an engineer and RAF/civil pilot I really have to speak out.
I've said before: a thumper can happen to anyone and I can certainly admit to a few. This is about risk management, in general terms,
before getting airborne.
