Woodbury - Good Hill Farm Airport 1956

From the Connecticut State Historical Preservation Office

"In 1956, the first parachute club was established called “Parachutes Incorporated.” In the parachuting milieu, this farm is known as the “birthplace of skydiving in America.” The first stabilized free fall in North America took place at Good Hill Farm. There, the members used (Sebastian "Batch") Pond’s Cessna 170 plane to parachute from. In 1959, the club moved to Orange, Massachusetts."
