The Private Jet Cessna Citation CJ2/CJ2 Plus is based on the design of the CJ1 but has 20 per cent more cabin space and adjustable, reclining seats for more comfort and leg room. Compared to the original CJ2, the newer CJ2 Plus has better avionics and a faster cruise speed. The configuration of this private jet can accomodate from six to eight seats, and has been developed with NASA and Boeing. Powered by two 1,900 lbf Williams FJ44s engines, the 10,000 lb aircraft has a trailing link undercarriage for smooth landings and can be flown by a single pilot. Its fuselage is 11 inches (27 cm) shorter than the Citation I's, but has a lowered center aisle for increased cabin height.
