I'm not a fan of this sort of thing as much as the intention is well meaning. What price do we put on risk?
There are well established organizations that do aeromedical work in at times a very challenging environment, this is no place for Pvt pilots or even more advanced pilots to be when there would be a level of 'pressure' on the pilot to complete the task.
The biggest trouble is pilots always tend to overestimate their abilities especially in the decision making process!
The planes themselves are not the real issue, CASA have it all wrong in that area.
I would never put one of my family members on one of these flights, too risky, but that's just me!
