It didn't take long for Columbia Aircraft to get its first members of its 300-Knot Club. The club was announced at EAA AirVenture and six Columbia 400 pilots have provided photographic evidence of flying at a ground speed faster than 300 knots. The fastest recorded speed so far is 334 knots, which is about 100 knots faster than the Columbia's top true airspeed in level flight. The club was started to draw attention to the twin-supercharged, 310-hp composite aircraft as a "purpose-built speedster," said spokesman Randy Bolinger. "People purchase a Columbia because they want to fly comfortably as fast, as far and as safely as possible in an aircraft that was engineered around a 310-horsepower twin-supercharged powerplant all the way to the fringes of the envelope," Bolinger said in a news release. "But the bottom line is that flying a piston single should be fun. The 300-Knot Club is just another way for the Columbia community to bond and have fun while doing what they love to do."
