Have not seen the details on this but:
The first post suggests the poor fellow had already departed. I doubt it since not much point in making an emergency landing then.
This incident highlights the problem with present ETOPS/LROPS planning. Assuming the patient was still alive but critical what is the point of landing at the nearest airfield when you cannot get the patient off the aircraft? Crews need far more information on potential diversion airports to make sound diversion decisions. Even if Stornaway had an airstair I would doubt if the community has the sort of advanced medical facilities needed for this type of emergency.
We need to wake up to the fool's paradise we are living in that implies the only item we need for a diversion airport is a long strip of concrete.
By the way, I flew one of the first two single jet aircraft into Stornaway (it was a two ship formation). Charming place but a bit cool.
