07/31/2012. Remarks by Walter van Tilborg: "The P-5 Sport was an original homebuilt single-seat sport design of Paul Poberezny (founder of the EAA and its President at the time), and was built a little help from his wife and brother Norman, eventually other EAA members pitched in. The aircraft was based on the pre-war Ace Baby Ace fuselage design and was built with modified Luscombe 8 Silvaire wings and a Piper J-3 Cub landing gear. It had an 80 hp Continental A80 and first flew on July 7, 1959.

Between May 1 and May 30, 1960, the aircraft was used on a 13,100 mls (21,082 km) tour across the USA and Canada to promote the EAA and to publicize the reliability of amateur-built aircraft. During this very successful trip the Pober Sport, flown by the Swedish engineer Anders 'Andy' Ljungberg, visited 72 cities and each of the 48 continental States in 121 hr and 25 min of flying time. The aircraft later received an 85 hp Continental C85 engine and in 1976 the sole P-5 Sport joined the EAA Museum collection."
