Some of the rarest aircraft that fly show up at the Heritage Invitational. The only flying 1956 Taylor Aerocar drew crowds all day long, and owner Ed Sweeney seemed never to tire of explaining how its wings detach for road trips. “How does it fly?” one onlooker asked pilot Eric Sweeney, the owner’s son. Eric, who owns Auburn Airplane Works in Auburn, California, answered, “For a car, it flies really well. For an airplane, there are probably others out there ….” That’s a Douglas DC-3 parked in the background, behind the fans dressed in the orange uniform of Section 3, a cheering section where fan is truly and famously short for fanatic.
