Looks like an ICBM to me. Best case it was a secret launch. Worst case it’s a Chinese missile designed to show us that they can hit us by surprise if they want to. Obviously it would have had to have been aimed away from the US so it would be apparent quite quickly it’s not an attack. Normally we wouldn’t do that kind of launch without informing the Russians, lest they get a little restless with their finger on the button. Scientists are saying it’s just a jetliner with a contrail, but that doesn’t compute if you look at the video. The trail wiggles like you’d expect a missile to, and jets normally don’t have glowing balls of fire coming out of their tails.
