In reply to Tallie:
After watching the documentary mentioned in the OP YouTube then took me to a series called 'Alpine Rescue - Angels of Mont Blanc', made in 2001 for Channel 5:
Also well worth watching, although it did make me wonder how I've survived my trips to the Alps. What struck me was how ready they were to show the blood and broken bones, and even dead bodies, unlike the 999 emergency programmes all over TV now, which all usually seem to end happily.
