The guys in the lower left at 1:22 act so nonchalant, I think he even shrugs. "Aircraft fire? Meh."
There's a take-off at 2:47 in the upper left-hand corner. I assume that normally when there's a fire like this, take-off's are halted.
I thought I remembered seeing something similar somewhere else before: Raw Video of Plane Exploding As Passengers Flee
(This video is a good deal more amazing.)
The Wikipedia article on the accident: China Airlines Flight 120 - Wikipedia
Finally, I think this thread should go in the General Aviation
subforum. Not that it's necessarily in the wrong place here.
EDIT: So apparently I missed the fact that the original Live Leak video included the initial explosion as well. Guess that's what I get for skimming through both the post and the video.
