Quincy, Massachusetts – September 3, 1910
On September 3, 1910, aviator Clifford B. Harmon was participating in the Boston-Harvard Aero Meet being held at Atlantic, Massachusetts, a village within the town of Quincy. While taking off in in his biplane, one of the wheels sank in the soft wet dirt some of which accumulated on the landing gear and made the aircraft unsteady. Just after takeoff, while at an altitude of about forty feet, he crashed in a marshy area. The aircraft was wrecked, but Harmon escaped injury.
