The trustees wrestled with how to treat space flight. Bound by the court to offer only three trophies, the trustees first agreed that "feats of piloting in both earth orbiting or outer space vehicles will be considered for the Harmon Awards provided the vehicles are controlled by their pilots rather than from the ground." The advisory committee directed the trustees to alternate awarding the aeronaut trophy between balloonists and astronauts, but the trustees decided to offer the aviator award to aviation and astronaut recipients. A fifth trophy was created in 1969 to honor achievements in space flight.
