The Marine Corps has finally finished investigating a midair collision off the coast of Japan that killed six Marines in December.
The collision of an F/A-18D Hornet and KC-130J Super Hercules was caused by an inexperienced fighter pilot who conducted an unusual maneuver, hitting the back end of the tanker aircraft during nighttime refueling operations.
But there were other issues, as the investigation also called attention to inadequate oversight of training and operations by squadron leadership and an unprofessional command climate within the squadron.
In the wake of the incident, the commanding officer, the executive officer, the operations officer, and the aviation safety officer were all relieved of their duties.
