but the clear and logical answer seems to be - yes
.
Yes because the duty of care has been transferred away from yourself to the medical unit.
When I looked into this it was for a very good friend who had a dying relative who s sole wish was to return to their hometown in the UK.
The family were happy to take the risk and give me a letter absolving me from any blame if the worst happened on the flight.
Infact even such a letter was not 100% watertight! The only way was for his Doctors to approve the transportation which they would not do so I did not touch the flight friend or no friend. He died the day after I was supposed to fetch him.
Ok mine was a non money making private flight but the principal holds true
