Some may be missing the point. It is not the complexity or simplicity of the system that is at issue. He should not have involved himself to that degree. I would have thought that the systems mentioned by Bally Heck warrant sufficient concern.
I would expect the pilot's peers to defend him and reasonably so. No doubt MyTravel are only to happy to defend him - it is probable a fair amount of commercial pressure was the reason this whole episode started!
However, when we get the full story we'll probably find it never happened.
