Sorry Steve, I misquoted. Smart stated 250 metres, not feet. I agree with you, he would only have seen a certain percentage of the aircraft's descent, but what he did see evidently made a big impression on him.
Yes, if this was a rotors not turning descent I'm amazed the toll wasn't higher.
But if it was a rotors-still incident, then it's nothing like the 2 previous EC-135 losses. Meaning I hope they get their finger out while other crews are still flying 135s.
At least I read Eurocopter are sending a delegation and the German AAIB to Scotland.
