I did and didn’t see what he was talking about.
Where does this alleged missile come from?
It was shot straight down from an invisible plane, of course. /S
Or, a missile was shot from the ground, it slowed to a stop and then it turned around and went back down. /S
Now the truth. It was a piece of smoking debris. It was smoking more at the beginning and less as it the rises. The wind disperses the thinner smoke at the top more quickly than the thicker smoke at the bottom.
