Debra Hauser Sentman shared on Facebook that she read about Ernst Buehl, who was the leading pilot for the air mail service established between New York and Washington that was centered in Bustleton, Philadelphia. He learned to fly from Orville Wright. It was at his airport, the Flying Dutchman, that pilots began to fly helicopters.
