Both were out of the atmosphere in a quarter of the time that this "missile" was recorded travelling. Maybe faster.
They launch, they're up in the stratosphere in a brief moment, and then they disappear into space like the taillights of a car driving off into a foggy night. The contrails go wildly screwy in a zig-zag fashion all over the sky in just a few minutes after launch.
I'm thinking that this mysterious "missile" is a jetliner or a Gulfstream corporate jet.
That's what I have seen whenever they launch them to shoot them down with interceptors from Vandenberg. Also the contrails stay in the sky (stratosphere) pretty much forever until it gets dark. They don't dissipate.
That's caused by wind shear. The wind blows in different directions and different speeds at different altitudes.
They will hold a launch if the upper level winds are out of spec for that particular vehicle.
No. It is a solid fuel rocket on a low trajectory away from the cameras. If you look closely you can see what may be staging at the end of the tape just before it cuts. You can see it leaving the atmosphere as it passe through the high cloud layer. It is not going to orbit but way downrange fast. Notice the expanding plume at the start of the trail. Contrails do not do that. but SRB’S do.
