Oh totally agree that its not in the same band as our Brazilian counterpart.
But you have to admit, still a few questionable points to raise.
Just because you're out of the hv band, doesn't make you invincible. I don't know the aircraft type but if its a single and your engine farts at that height, you need good skills to put the aircraft down safely, especially on that type of surface (potentially frozen river).
Increased risk of bird strikes.
Misjudgement of pilot when flaring to clear trees - you clip the disc and you could be in a world of poop.
All of this in a place where if you have an accident, rescue probably won't be fast.
Maybe I'm a kill joy, but if I want to fly like that, my pax would be informed of the risks and I certainly wouldn't have it posted on the web.
