A driver is dead after their car crashed the main gate of Travis Air Force Base. Officials are treating it as a possible attempted attack. The FBI is now leading the investigation. "The car basically blew up," said witness Kamren Hernandez. " It was nothing anymore." Hernandez couldn't believe what he witnessed Wednesday night from his family's restaurant just feet from the main gate at Travis Air Force Base -- a black SUV exploding seconds after breaching security gates. Henandez' father, Lamar, saw it too. "It kept exploding -- boom boom. Kept on going."
