The Citation X is the fastest non military private aircraft, with cruising speeds of Mach .9 or 590 MPH.  This jet will climb to 43,000 feet in just 30 minutes at its maximum takeoff weight, lifting you swiftly to transcontinental and transatlantic crossing altitudes.

In addition, the Citation X private jet is certified to fly as high as 51,000 feet - where fuel efficiency is optimized and airline traffic is nonexistent.  

The full-length stand-up aisle stretches 24 feet. Each Citation X private jet's interior is unique and individually outfitted to the specifications of the owner.
