In a release issued by the company Sept. 23, 2016, SpaceX outlined some of the findings of the Accident Investigation Team (AIT) – composed of SpaceX, the Federal Aviation Administration, NASA, the U.S. Air Force, and industry experts – and on the condition of the infrastructure at Launch Complex 40 (LC-40).
