Gil Leyvas claims that he observed it for 10 minutes. The LAX webcam shows that the object was travelling towards the mainland. Remember that Gil Leyvas was positive that it was going away from the coast.
That would mean that this claimed ballistic missile was heading inland over mainland US. In that space of time then such a ballistic missile travelling at speeds would be by then thousands of miles away.
Gil Leyvas stated
"Leyvas said he zoomed his camera in and kept it on the vapor trail for roughly 10 minutes. "It was unique. It was moving. It was growing in the sky."
This video is from December 2009 off California. Again it would be the slowest ballistic missile in the world. Yet another example of how people can misinterpret an aircraft contrail.

The following link is to a report from Patrick Minnis, a contrail expert in the Science Directorate at NASA's Langley Research Center in Hampton, Va. It highlights the point that even experts can be initially fooled.
