(AP Photo/Lenny Ignelzi) Two US Marines were killed when the Super Cobra attack helicopter they were flying in went down in flames during a training exercise at California's camp Pendleton. Firefighters were battling a 120-acre brush fire triggered by the afternoon crash late yesterday. It was the third major accident in the Southern California military base in three months. A similar helicopter crash in July killed one Marine and injured five. Two Marines suffered broken bones when they ejected from a crippled fighter jet that crashed into the Pacific last month during a Camp Pendleton training exercise. Officials are investigating the cause of yesterday's crash, reports KGTV San Diego. "It's a tough time for us," said USMC Maj. Carl Redding. "Anytime we lose Marines whether in war or in training stateside it's hard for all of us." Read These Next The Bezos-Sanchez wedding: guest list, cost, the dress, and more.
