Hughes - you are right that we can drop off our twig at any time but this is all about probability and risk vs reward. A medical board took his licence away for 2 years because they deemed the risk of him having another problem was too high!
If I had had a TIA or minor heart attack I wouldn't dream of taking passengers with me in a vehicle - I had the same argument with my brother after he started having fits due to a brain tumour from which he subsequently died, it is just irresponsible to put other lives at risk when there is a choice - and there surely was a choice in this case.
I am all for people doing brave things to save lives - if it is only their own lives they are risking - as I said before, did he make it clear to the police and medical teams the real risks involved in letting him fly them?
I suspect not.
