There’s video footage on instagram of the chopper going down. As I posted in the other thread, I’m no expert but this is how it looked: The whole craft was spinning wildly, and it looked like the main blade was still spinning. The chopper dropped fast and crashed with a big fireball. That area is very popular for hiking, so you could hear people screaming and strating to cry in the background. Pretty rough to watch.
Stuff gets weird when everyone rushes to be the first to report something catastrophic like this.
Loss of tail rotor?
If the aircraft was spinning, then it apparently lost control of it’s tail rotor. The TR counters the direction of spin imparted by the main rotor blades so that the aircraft can fly straight.
