A primary historical in-flight exposure of the Spirit of St. Louis instrument cluster during airspeed calibration trials. The composition prominently captures Charles Lindbergh's left hand wearing a heavy leather aviator gauntlet gripping the base of the control stick. Instruments record cruising flight parameters at 98 mph indicated airspeed, 1,600 engine RPM, and 1,100 feet altitude, providing direct photographic proof of Donald Hall's airborne flight test logging.
