I don't really understand the final part where it regained alt and then dived back in. Maybe only half the wing came off? From the film, the part he filmed would be right after it regained alt. Also interesting is the camera guy was able to know right where it was in rural China to catch the last second of it. I'm surprised too it was able to leak to the press. It was a very short video, curious how long he was recording. Looked like the last wing broke off there.
If all is as it appears, truely devastating.
