On May 30, 1972, Flight 9570 departed Dallas Love Field in Dallas, Texas at 06:48 Central Daylight Time, and proceeded to GSW to perform training approaches and landings. Flight 9570 requested an ILS approach to GSW's Runway 13. The clearance was granted, and Flight 9570 was advised that the American Airlines DC-10 was already in the traffic pattern to perform "touch-and-go landings" at GSW. Flight 9570 landed without incident.[1]: 1–2 After landing at GSW, Flight 9570 received new takeoff and climb-out clearances, made training maneuvers including an ILS missed approach. Flight 9570 then requested approval for landing on Runway 13, behind the American DC-10 which was also inbound for a landing on the same runway. The air traffic controller gave Flight 9570 clearance to land on Runway 13 with an advisory "caution, turbulence".[1]: 2  The controller did not advise the DC-9 that they were following a "heavy", though the controller did advise that they were following a DC-10 which experienced pilots should have known was a "heavy" aircraft.[1]: 14–15 On approach to the runway, the DC-9 began to oscillate about the roll axis, then rolled rapidly to the right. After rolling 90 degrees to the right, the right wingtip struck the runway. The airplane continued to roll to the right, until the fuselage struck the runway in a nearly inverted position.[1]: 2  The aircraft was damaged by impact forces, and destroyed by a subsequent fire. All four occupants were killed.[1]: 3
