Great result; I've never heard of a similar event for helicopters (whereas there are loads of PAX lands the plane stories). It would be interesting to hear more about what she actually did ("I reached over and pulled the handle"). Pretty amazing for someone with no understanding/training of helicopters.
A colleague of mine (aerial filmer, not a pilot) brought an AStar in for a controlled crash a few years back after the pilot became unconscious mid-flight in a remote area. The machine was totaled but all aboard survived. My colleague had extensive leg surgery to be able to walk again., but it's still a miracle. He had spent a lot of time in helicopters but had no flight experience.
