Marine Corps crash dampens a happy day

A bittersweet day for the Marines yesterday --More than 170 Marines who recently returned from a 7-month deployment to Afghanistan visited 16 wounded warriors from their unit at Walter Reed National Military Medical Center. At the same time, Two Marine Corps helicopters collided over a remote section of the California desert during a nighttime exercise, killing seven Marines in one of the deadliest military training accidents in years. An investigation into what happened is underway.
