The first Citation CJ1 was delivered on March 31. The proud recipient was the Commercial Envelope Manufacturing Company, head-quartered in Deer Park, New York. \rThe buyer began utilising business aircraft in the mid-1980s. It purchased its first aircraft, a Cessna Conquest II, in 1997. The CJ1 will be used for a variety of missions, including transporting customers to its facilities for on-site press checks, the delivery of manufacturing parts, and ferrying some of its 550 employees between bases. \rStated vice president Steven Kristel: "We noticed the CitationJet on an airport ramp that we frequently visited. Our pilot talked to the owner of the CJ, who gave the aeroplane an excellent recommendation."
