Until Gulfstream achieves full certification and starts delivering its G650, Cessna’s Citation X can still claim its spot as the fastest civil airplane in the sky. With its Fadec-controlled Rolls-Royce AE3007C1 engines, which are about the size of some single-engine airplane fuselages and each produce 6,674 pounds of thrust at sea level, the airplane can cruise near the speed of sound at Mach 0.92. The Citation X earned Cessna the Collier Trophy when it was introduced in 1996. In 2010, Cessna felt the popular business jet needed a face-lift and announced a slightly larger version, simply called “The Ten,” which is expected to hit the market in 2013 with a Garmin G5000 touch screen panel in place of the X’s Primus 2000 Elite and lots of other upgrades.
