Okay, I watched. Weird, but I’m not convinced it’s an incoming missile.
For one thing, the “missile” moves upward faster than the explosion’s plume. That leads me to think that a small object at the site of the explosion was propelled upward through the blast. For another, the “contrail” of the “missile” is moving _upwards._ That’s counter-intuitive to something that’s supposed to be coming down.
There is no upwards track. The contrail appears instantly.
