Anyone who has a problem with the ruling in this case really needs to go and get themselves on a proper flight safety course - the sort where case studies analyse the events leading up to an accident and highlight where that chain of events could be broken and the accident prevented.
This pilot was (and possibly still is) an accident waiting to happen - from his self-denial of his medical condition (enough doctors seem to believe he was at risk) to the insistence that he was the only pilot who could fly those 'missions'
Fortunately for all involved, the last hole in the Swiss cheese didn't line up (through luck rather than good judgement) and he managed to rescue the chap on the hill.
The emotive part about the casualty not surviving without the rescue is a red herring - he was carried out many hours later and internal bleeding would have done for him long before that.
Mr Armstrong was foolhardy to the point of recklessness with other people's safety and he has, as a serial offender, been appropriately punished.
