My response is just a warning to any pilot especially of private aircraft who maybe asked to do a friend a favour.
What is well intended and maybe even done for free could end up as a nightmare if anything goes wrong even if family or the ill person sign a letter removing responsibility for the flight from the pilot.
I did do a medical flight on a private jet but the patient was accompanied by a Doctor and nurse and relevant medical equipment and medication for the trip.
The other potential trip which was declined (thankfully) was in a piston twin and unpressurised which itself could cause problems.
