The investigation also revealed that he was not properly recertified to fly the F-16 after a 20-year hiatus. He had only 102 hours of flight time on the F-16, 82 of those were back before 1994. He should have undergone F-16 centrifuge retraining but the unit gave him credit due to his experience on the F-4.
