Had he stayed in ground effect a few seconds more and built up a little more speed, he might have got out of there, albeit with some foliage in the landing gear. Unless he got the gear up right away, which also seems wise to me in this case.
Not that I would've tried what he did in the first place, though...

And yes, no flaps... why??
This is classic "don't" footage- you can clearly see that he's trying to get the nose up but she's not having it, because the wing is stalling... it wallows and begins to sink, because the pitch input has just made things worse. I watch that, and my hand moves forward instinctively.... "get the nose down!"
Worst part is that when the aircraft does touch down, they're doing OK, considering.
But when it hits that berm... :o It just hasn't decelerated enough. I wonder if he even pulled the power back as it touched down...?
