I have tried to offer up several links: I have also searched for the orig video, first helicopter cameraman interview, etc all unsuccessfully. All the information I can find is in snips and pieces, and then mis-quoted or repeated at second and third hand.
I recall someone saying that they TIMED the ascent that they saw on a piece of tape at 47 seconds and that this covered half of the exhaust creation.
So, if true, that would mean 94 seconds of plume, balance was of back-lit smoke slowly expanding after the object has grown smaller and disappeared.
I did not time this 47 seconds.
I would like to.
Literally, there is much less info out there now than was there the first day - I thought the information and interviews would become more numerous, not less, so did not try to download or save.
Check with others here, they have done more than me perhaps- and have more links maybe.
“We do have flight data from several possibles, especially an US Airways Flt 808 and a UPS bird flying a similar track.”
It is impossible to exactly correlate any known flight path to an unknown flight path.
Apparently, what is obvious to some is not obvious to others ...
The only CBS Early Show I can find on the story is "Military Says Missile-Like Object Wasn't Missile" on Nov. 10.
The only portion of this story concerning the duration of the event is (referring to the cameraman):
He zoomed his camera in and stayed on it for about 10 minutes. To him it looked like an incoming missile.Video.
