Agree with all of the above (and I have, too, been on medevac flights, albeit not as pilot), however, there is one comment that intrigues me:
Legally, this is tantamount to dying in France; yet, legally, he has not yet entered France ! !
I've always been under the impression that once airborne, you are in the country (and hence jurisdiction) of the country of registry of the a/c. So in this case, assuming Pace is flying a G-reg, the UK, no matter which airspace you're in. This situation would obviously change once on the ground.
