As part of the 707 prototype (Dash 80) demonstration program, representatives of the Aircraft Industries Association (AIA) and International Air Transport Association to the Seattle's 1955 Seafair and Gold Cup Hydroplane Races held on Lake Washington on August 6, 1955. The Dash-80 was scheduled to perform a simple flyover, but Boeing test pilot Alvin "Tex" Johnston, instead performed a barrel roll to show off the jet airliner.
