Yes, it is amazing. Not sure if dangerous.
:salute: to the pilot. Amazing display of skills {:)}
I am not a real heli pilot to say decisively whether or not this is dangerous. In my perspective, a lot of skill and practice has gone into this. At least two things are at stake here at a grand level: life and money. Helicopter, as a complex machine exhibiting complex flight dynamics, catapults the risk to a different league. This guy is flying too close to ground and chances to recover from a mistake are slim. Similarly, pressure to perform flawlessly can easily invite trouble. In addition, I don't know what exact heli is this but i am quite sure that helis at that time were not as pilot friendly as they are now.
Anyway, lovely flying..
