My first thought was that it would be an engine fire etc. But then again, thats not good either.
This would turn up in the news though, eventually, right ?

I have seen something similar to what you are describing that was left behind the November 1998 Boloide during the Leonoid Meteor shower. If you search around the web, you can find a picture of that Boloide, as an observatory well north of where I was at the time caught it.

It wasnt a bollide. I judged the elevation of the "contrail" to be about 10,000 feet. At that elevation, we would have heard it, trust me. Last year we had a monster of a bollide explode about 100 miles south of us, and we heard it clear up here. I find it odd too that a bollide "contrail" would go parralell to a normal white one.

Not to argue with you or anything, but I have seen quite a few bollide’s and I have never heard one make noise. I think that the one up by you last year that made noise was because it exploded over seattle.
If you live by this naval station, maybe it was a jet running its afterburner (though that is usually pretty loud), or one taking off with JATO ( again pretty loud). Of course noise is going to be affected by distance from the plane, altitude and wind direction. Was this out over the ocean?

I saw an odd black contrail the other day too. Cant say I've seen anything like it, it stood out so much. It was in a completely clear area of the sky, quite thick and almost pitch black. The odd part was that it was so uniform, like a piece of string someone cut off. It didnt fade in either end. I cant describe how long or high up it was though, I'm lousy with distances. Measuring by hand, I'd say it was a full hand length over the horizon, about the length of a thumb.
But I'm not very familiar with cloud behaviour, it could be something ordinary. This was in Sweden so its not connected to the first post.
