It's a tough situation when the aircraft does not do what you want it to do. Adrenaline starts pumping. It's hard to be as cool and calm as a test pilot, and we tend to want to just get the dang thing on the ground because we don't know what *else* is going to go wrong. The 407 did have a history of tail rotor problems.
That's where the training comes in and why I wondered how much, if any, he had done.
If you have never trained for such a scenario then you will be poorly placed - and most likely panic if it doesn't go right as per the video.
If you have trained for it, there is no guarantee you will get it safely on the ground but you stand a far higher chance of applying some basic techniques to maximise your chance of survival.
If you have no idea how to deal with TR malfunctions, you really shouldn't have a licence.
