In reply to Swamp76, the AS350 had all the rotor blades tied down, even the tail rotor blades were locked with the pin, as a thunderstorm was aproaching, the problem was the deflexion that the blades had on the way down, they swinged more than 1 meter, and the fuselage was dragedd some centimeters to the side, eyewitness said they though it was going to roll over. But you are right, there are always more than one way to see it...
