The U.S. Coast Guard and Navy are searching for as many as nine victims of a collision between a Coast Guard plane and a Marine Corps helicopter off the Southern California coast. The crash, reported Thursday evening, took place about 50 miles from the San Diego County coast. A pilot reported seeing a fireball near the crash site. Seven people were aboard the C-130 aircraft, and two were aboard the AH-1W Super Cobra helicopter, which was on a training mission. Debris from the C-130 has been found.
