If there is not enough power to lift straight up, they circled around in the jungle till there was enough transitional lift. chickenhawk lowlevel hell, i'm not making that up
the rest is me asking a question to Seakhawk
if you can't be bothered to contribute and tell me something, then why bother responding at all?

A few of the things you mentioned are somewhat correct and I'm familiar with Huey ops in Vietnam (I think I read that book as well). You're confusing terms...
The pilot in the video is approaching the ridgeline at what appears to be almost a 90 degree angle (no escape path) and way too fast. His descent rate looks high also which means he's pulling in an armful of collective at the bottom. That sets him up for more problems. Yes, a helicopter will use less power while in ground effect but pinnacles offer virtually no ground effect. Completely different than hovering over a concrete tarmac or runway. He got himself into that mess all on his own. He did have some skill pulling it out at the bottom and flying away from the ridge, however.
The rest we're just playing armchair quarterback - we have no idea what his weight is, the wind is (is there any at all?) or the DA. He may have also experienced loss of tail rotor effectiveness (again, we don't know what the winds were). Some Bell products are more more prone to this than other makes.
