It's actually CGI... I have always had a kind of knack for spotting things that are just a tad 'off'.... Indeed, this video looks quite convincing... as a matter of fact perfect....until they show it landing.... at that point in time, the manner in which the plane moves is just a little too smooth..... other than that...it's a helluva video.... I think it was a commercial for something overseas somewhere.... could be wrong...
[edit]
I just watched it again for grins.... just pay attention to the part when the plane rolls to touch its mains on the grass..... and then teh roll out... if you were a believer to begin with, I doubt you will be if you just watch that part....
