During both the practice and the actual flyover, Holland's aircraft flew at altitudes below 100 feet (30 m)—well below the established minimum altitude—flew steeply banked turns in excess of 45°, exceeded pitch-angle limits, and executed a wingover. Although not specifically prohibited, the wingover was not recommended because it could damage the aircraft. After witnessing the flyover, Colonel Weinman and his deputy commander for operations (DO), Colonel Julich, orally reprimanded Holland, but took no formal action.[1]: 3–4 [2][page needed]
