Pentagon Stumped

Yahoo news:

The Pentagon said Tuesday it did not know what created a vapor trail that crossed the skies off the Southern California coast and resembled a missile launch.

Video posted on the CBS News website shows an object flying through the evening sky Monday that left a large contrail, or vapor trail.

Pentagon officials were stumped by the event. "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.

While the vapor cloud captured on video resembled that created by a rocket in flight, military officials said they didn't know of any launches in the area.

It could have been a reverse meteorite. Unlike regular meteorites, which are far more frequent than legitimate DGUs, these reverse meteorites are rare indeed.

Of course the Pentagon doesn't know this. What do they know?
