Yep those medicals are very important for pilots.... A lot of us have found out about pending long term health issues early because of them but have they ever stopped a crash happening?..... we will never know for sure.
What we do know is that every pilot who died or has become incapacitated in an aircraft had a valid medical.
In this case Mr Armstrongs so called medical problem turned out to be not a problem and at least one person is alive because of it.... please remember nobody has yet challenged the fact that all other options had been exhausted to save this persons life.
The doctor flown into the site was in fact the doctor who initiated the suspension of Armstrongs medical and was fully aware of his medical status and still got in the helicopter.
