Missile launches off the coast of California are commonplace --but this one was a mystery. Military officials said early on it didn't represent a threat to the United States. They also said it was not a launch by a foreign power. The video captured by a news helicopter showed an object shooting across the sky and leaving a large vapor trail. DoD said it wasn't involved, and that it might have been created by something flown by a private company. Which could lead to big trouble for that company.
