Unlike which plane, exactly?
You are welcome...and nobody has disproved anything. And even the Air force said they did not know what it was...if it was a plane they would have dispelled all and said so. THe contrail began at the bottom unlike a plane and the immediate trajectory was not that of a commercial plane....as I said , you guys have some screws loose..please tighten or all of your commonsense may spill out!
