Hmm, not so sure it's not a fake. If the model seen on the ground is supposed to be the one having taken the video, then it's a slow one and in the video sequence it takes a quick 5 sec spinning to come down from the 737 height.
That type of model can do this in 50-75ft easily. So, how close to the threshold was the bloke flying?
Even if it's not a fake, be aware that it actually happens more often than one thinks (been there, done it, got no T-Shirt
.)
