I don't get how a missile could cause a contrail and spiral that looked like that unless it was some new super-high-power plasma thruster rocket... Unless my experience in rockets is totally wrong, there is no conventional propellant that leaves a blue contrail that lasts that long, or that dissipates like that. That's the strangest part--I've never seen a rocket contrail dissipate like that. Ever.
So, three logical explanations:
1. The Russians just fired off some new super-awesome engine technology and the world should be afraid.
2. Just a CG composite made to mess with people (though the level of motion matching and similar quality suggests either a lot of work went into it or it was actually real).
3. Aliens frakking with our minds and someone actually capturing it on film because high-quality cameras are becoming more and more available.
