A new air speed record was set at the Experimental Aircraft Association's (EAA) AirVenture in Oshkosh, Wisconsin on Wednesday when pilot Jon Sharp flew 3 kilometers in just 18.75 seconds.

Sharp, who founded Nemesis Air Racing in Mojave, California with his wife Patricia in 1990, broke the 19-year-old record of 331 mph when his Nemesis NXT hit 356 mph on a speed run above thousands of fans. Crowds gathered to watch Sharp, who helped pioneer the design for neoteric experimental technology (NXT) kit aircraft, who will try again on Saturday to go even faster.

Flying a Lycoming-built Thunderbolt engine, the Nemesis NXT took aim at the 3 km B1-b Speed Blast record amid unfavorable mid-afternoon weather conditions. Despite high winds, Sharp was able to easily surpass the old record and is enthusiastic about trying again on Saturday.
