Near this site on September 21, 1933, Richard C. duPont was launched from Afton Mountain in his Bowlus sailplane, Albatross. Four hours and fifty minutes later he landed at Frederick, Maryland, establishing a United States distance record for sail planing at 121.6 miles, almost double the previous U.S. record of 66 miles.
