We were discussing this incident elsewhere online, and a friend says that a 747 once landed at Jersey Airport (EGJJ) due to a medical emergency. Pax had to be removed in batches to the UK, the seats removed and a minimum fuel t/o followed - with (he says) the aircraft only just making it. He makes it sound like a carrier take-off, with the a/c dipping down as it cleared the end of the runway over the sea.
Jersey has around 5500' of runway, which on the various examples mentioned in this thread doesn't seem that dramatically difficult. I'm having trouble believing that there wouldn't be better places to put down with little time penalty, and I can't find any reference to such an incident anywhere.
Can anyone confirm this?
