The Anglia video shows a better perspective than the photo. There was a report they whacked a tree branch on the way out, but hard to say it that made any difference. They would have been going at a pretty good clip at impact to shred the fuselage like that.
Lots of chest-beating "I would never do that", even by offshore pilots that do exactly that on those dark misty nights coming off a deck pointed at ink. You follow a disciplined profile and it works. Every time.
Hard to imagine being able to keep a 139 anywhere near the ground, but who knows what their takeoff plan was. We'll know soon enough.
