This Week in Edwards Flight Test History

  • Published

On March 28, 1983, the director of the F-15 Combined Test Force, Lt. Col. John M. Hoffman, flew the first of 27 high-angle-of attack-test flights on an F-15C with the test nose boom removed. This series proved that troublesome flight anomalies that had appeared on the F-15C had been caused by the presence of the nose boom and not by its conformal fuel tanks. This in turn removed the threat of severe restrictions being placed on the flight envelope of operational F-15C/Ds. (Edwards History Office file photo)
