Mysterious missile launch off Los Angeles? UPDATED: solution found?

Look, I realize the rest of the country is mad at California, but do you have to shoot at us, too?

The launch took place 35 miles west of LA and north of Catalina Island during rush hour last night. The footage above was taken by a CBS News traffic chopper that was in the air at the time. Both the Navy and Vandenberg AFB are denying it was one of theirs, so…Whose was it?

Troubling question: And just where did it come down?

UPDATE: Allahpundit speculates at Hot Air.

UPDATE II: WUWT may have the solution – a jet’s contrail over the sea combined with an optical illusion caused by the Earth’s spherical shape.
