Our thread starter has told us of an interesting scenario. But I just wonder what the crew would have done had the passenger's condition worsened. Also you have ask what would have happened if the passenger's condition was such that a medic would advice an immediate diversion. It would be very difficult to explain after your passenger dies as to why you didn't take medical advuce when it was standing right in front of you. That would possibly lead to an even more interesting case in court. Lots of 'ifs' I know but it is important to know how 'being safe' can sometimes backfire and hurt you or others.
