The air force launches the ultra-high-level balloon Man-High II in Crosby. Pilot David Simons reaches a record 101,516 feet (almost twenty-one miles) before setting down in Elm Lake, South Dakota. The flight takes thirty-two hours and ten minutes, but Simons occupies the balloon's capsule, from pre-launch to landing, for forty-four hours, a period longer than Charles Lindbergh's solo flight across the Atlantic.
