Sure is, but what is more puzzling is the way the crop appears to be still standing at full height immediately behind the wings at 0:58 sec.
There is probably a better explanation, but the only one I can come up with is that the height of the wing when the aircraft is level on its belly is at the point that the plant stalks bend when hit rather than shear off. If struck lower, the stalks have less room to give with the impact and shear instead of bend. The wavy pattern was produced as the plane rolled from side-to-side during the landing/crash slide. The lowered wing sheared the stalks whereas the upper wing merely bent them. Any way, that's my explanation, and I'm stickin' to it until someone comes up with a better one or bribes me with a beer (or two) to erase my post and go away. Or maybe an expensive way of making crop circles.
By the way, congratulations to the pilot flying. That was, in my opinion, as good an open field forced landing as it gets. Nobody injured, a little bondo (plastic filler), paint and vigorous buffing, and it's all good to go. Then, all that's left is to get it to an airport.
Cheers,
