He took the original pic from the news report of the incident, shown here
and compared it to an image taken from a webcam 24 hours later, when flight 808 was going by, shown here
The similarities would seem to suggest that the original incident was US Airways Flight 808.
Yes, now I think it is a 100% certainty that was a common contrail, probably from 808. The illusion was a strong one!
That's what I saw on Monday and Tuesday on my way home from work. Both contrails were in the same spot in the sky at the same time on both days.
IOW, it was Flt. 808, not a missile.
