How much headwind was there in the first Savannah clip? it appears more levitation than aviation
I mean, you could do something similar with full flaps in a C172 into 50 kts of headwind, but I don't think I'd want to be in the air with that kind of weather.
And as per spinex's comment, no room for error there--what could the windshear possibility be when you got below the level of those treetops? Can't imagine more than a breath of wind intruding at strip level amongst that cover.
