From a worldwide aviation perspective, this isn't an isolated incident. Not having been in the cockpit at the time, the only thing I'm fairly certain of is that they didn't intend to land on the taxiway.
Looking at the preliminary statement, the "holes in the cheese" are lining up already: long night flight, medical emergency, one crewmember down, landing just before dawn, late change of runway, strange lighting configuration, lack of electronic guidance, taxiway clear of aircraft, etc. There was a lot of pressure, some of it probably self-generated, to get the aircraft on the ground ASAP - this was the result.
I hope the eventual report will have some interesting learning points for the rest of us, so for the moment I would suggest not condemning the crew involved out-of-hand...
