drakeX's explanation is the most logical. I didn't realize the streak came from in front of the smoke, or I would've stated that. It was my first guess, but I didn't think it was in front of the smoke.
No, even with the force of the explosion, it wouldn't have flown like that. That object would be HUGE.. and when I say huge.. i mean the size of the frigging building is horizontally! As well as the fact that it would've been pulled down by gravity, and thus have been arching.
[edit] i correct myself, it would be *moving* the speed of a width of the building, not even the explosion or plain was moving that fast, so how could an object being hit by it be moving faster? And the object would be the size of two stories or more, i mean, look at it!
(if the object, were in fact coming from behind the smoke, and not an object right in front of the cam)
No plot? No problem! Come write with the worst of us!
