Late last month Cessna delivered its third Mustang, its first to a retail customer. The previous two deliveries were leased back to the manufacturer as demonstrators, as is customary for new aircraft. The airplane went to snow ski manufacturer Dave Goode, who was also the first customer typed in the aircraft. Perhaps a sign of things to come, Goode is also a private pilot with an instrument rating. The third Mustang is one of 40 the company plans to deliver this year.
