No he didn't.
The video of what looks for all the world like the contrail of a missile was shot Monday evening by KCBS cameraman Gil Leyvas from a news helicopter over Los Angeles.
"I saw a big plume coming up, rising from looked like beyond the horizon and it continued to grow," Leyvas said.
He zoomed his camera in and stayed on it for about 10 minutes. To him it looked like an incoming missile.
"It was unique. It was moving," he said. "It was growing in the sky."
I'd like to see the other nine minutes of the video. If its nine minutes of footage of the object creating a contrail, then its definitely an airliner contrail. If only one minute of the ten minutes of footage shows a craft creating a contrail, and the rest is just footage of the contrail itself, then its probably a missile.
