I was just looking at the video again.

Okay, we can rule out airplane, or at least a large multi-engine 'plane. If you can see the source, (e.g. the speck of the airplane itself) the contrails are split. They do merge together behind it a ways as the vapor trail widens out. If the 'plane is a four engine, you can see four trails if it's close enough or you use binoculars. (two sets of two closed spaced trails)

But, the one in the video just leaves one single big fat contrail behind it. I can't see even a military aircraft such as an F14 (or whatever, something with a single source tail nozzle, single or dual engines) leaving THAT LARGE of a trail behind it. The thing was large, very much like the satellite launching rocket they compared it too.
