Apologies if my first post here seems snarky, I don't really mean it that way....but having read through this thread a couple of times, um, RAT 5, you seem to be having a temporary attack of "missing the point". It frankly appears everyone involved considered speed of treatment to be the most important factor. They are quite correct time is of the essence in case of heart attack. Literally every second counts. If a ladder is faster than deploying airstairs - in order to get emergency help to the patient in time - then for heavens sake what does it MATTER what kind of a/c it was? They got him treatment within 10 minutes. Onboard a commercial aircraft in the middle of taxiing to the runway, that's a bloody miracle. You can hardly get an ambulance to most people that fast. Kudos to the F/O. Seriously.
