The guy who shot the video and posted it, who helped push the thing off the runway afterwards, explains that the owner (can't bring myself to call him a pilot) had failed to notice that the prop was fitted backwards.
And in the comments, the experts are queuing up to insist that if the prop was on backwards, the aircraft would have been pushed backwards!
Real
Dunning Kruger stuff, too ignorant to have any concept of how little they know!
