The finding of the Air Combat Command Accident Investigation Board were publicly released on 30th July, 2015. The US$ 14.1miilion aircraft suffered a starter-generator failure. During efforts to recover the aircraft the back-up battery had insufficient voltage to lower the landing gear so the decision was made to deliberately crash into nearby mountainous terrain. The wreckage was not recovered so the exact cause of the starter-generator failure could not be determined.
