The Miller JM-2 was an American Formula One Air Racing homebuilt aircraft that was designed by Jim W Miller and produced by JW Miller Aviation of Marble Falls, Texas. When it was available the aircraft was supplied in the form of plans for amateur construction.[1] Design and developmentMiller opted for an unorthodox configuration in developing a racing aircraft that would be as fast as possible on {{convert|100|hp|kW|0|abbr=on}}. The JM-2 features a cantilever mid-wing, a single-seat enclosed open cockpit under a bubble canopy, tricycle landing gear with fixed main wheels and a retractable nose wheel, and a single engine in pusher configuration, mounted within a fan shroud, with the spinner acting as the aircraft's tailcone. The fan shroud structure provides a place to mount the rudders and the tailplane is mounted high in T-tail configuration as an extension of the shroud. There is a small canard surface mounted on the nose.[1][2] The aircraft is of mixed construction, with the fuselage made from four fiberglass panels and the {{convert|15.0|ft|m|1|abbr=on}} span wing covered in fiberglass and resin-reinforced honeycomb material. As required by the Formula One rules, the engine used was a {{convert|100|hp|kW|0|abbr=on}} Continental O-200B powerplant, the "B" being the pusher-configured version of the engine.[1] The JM-2 has an empty weight of {{convert|630|lb|kg|abbr=on}} and a gross weight of {{convert|1100|lb|kg|abbr=on}}, giving a useful load of {{convert|470|lb|kg|abbr=on}}. With full fuel of {{convert|12|u.s.gal}} the payload is {{convert|398|lb|kg|abbr=on}}.[1] The JM-2 was further developed into the one-of-a-kind racing aircraft, the Miller-Bohannon JM-2 Pushy Galore.[3] Operational historyBy October 2013 three examples had been registered in the United States with the Federal Aviation Administration including the sole Miller-Bohannon JM-2 Pushy Galore. None of the aircraft remains registered.[4] One of the two stock JM-2s built was destroyed while racing in the Reno Air Races at Reno, Nevada on 15 September 1989, when it flew through a dust devil and broke up in flight, killing the pilot.[5][6] Specifications (JM-2){{Aircraft specs|ref=Plane and Pilot[1] |prime units?=imp
