CBS News: The Mystery Missile Launch

The Pentagon said Tuesday it was trying to determine if a missile was launched Monday off the coast of Southern California and, if so, who might have fired it.

Spokesmen for the Navy, Air Force, and other military organizations said they were looking into a video posted on the CBS News website that shows an object shooting across the sky and leaving a large contrail, or vapor trail, over the Pacific Ocean.
"Nobody within the Department of Defense that we've reached out to has been able to explain what this contrail is, where it came from," Pentagon spokesman Col. Dave Lapan said.
