Site of First Successful Rotorcraft Flight in the United States

On 1 June, AIAA will designate Pitcairn Field #2, in Willow Grove, PA, as a historic aerospace site. A historic marker will be unveiled at an 11:00 a.m. ceremony at the Tinius Olsen Testing Machine Company facility that now occupies the site.

On December 18, 1928, Arthur Rawson, a factory pilot for the Cierva Autogiro Company, and then Harold F. Pitcairn, flew a Cierva C.8W Autogiro from Building #3 at Pitcairn Field #2. The flights marked the first time a rotary-wing aircraft was successfully flown in the U.S.
