Six missing after helicopter crashes in Southern California. The device departed from the Palm Springs airport around 8:45 p.m.

and was headed to Boulder City, Nevada. Less than a week ago, a Marine helicopter went down in the mountains near San Diego during a downpour. The cause of the accident is unknown and the National Transportation Safety Board said it was sending a team to the scene. Boulder City is 26 miles (41 kilometers) southeast of Las Vegas, where the Super Bowl is played on Sunday.
