Cessna’s latest and largest addition to their Citation range of executive jets is the Citation Columbus which is based on the Citation X. The Cessna Citation Columbus can seat eight people and is powered by two Pratt & Whitney PW810 Turbofan engines which gives it a top speed of 970 kilometers an hour and a range of 7,400 kilometers. The plane will become Cessna’s flagship jet when deliveries start in 2014.
