Hi, thank you very much for the link, while I've seen a fair amount of flight-related videos, real and faked, this is a new one. I am puzzled though, the tool sounds like an american product, at least I've never seen that here in Denmark, however speaking of Denmark, that helicopter seems to have a "OY-" registration, to my knowledge only danish civlian flying machines have registrations beginning with that.
And I agree, it does look like a possible Chicken Wings strip.
Greetings
Frank
