I agree with B747 that a stretcher patient with medic back up makes the odds of an unscheduled landing less likely. I was o a flight recently with stretcher doctor and nurse and it was fine. I was also on a plane when a passenger unfortunately suddenly died. Bottom line is statistically the odds of an unscheduled landing virtually nil but you never now what will happen. But if you really think the pilot will put the plane at risk then you don't know much about flight safety protocol. As a final note you are not covering yourself in much glory here and just sound like abit of a coward sorry to say.
