Piper Aircraft was one of the companies that tried to bring a single engine bizjet on the market. While the concept aircraft of the PiperJet - official designation PA-47-2400J - has flown, the development was stopped before any production aircraft (to be named Altaire) were built. It is also a one-off aircraft in terms of external appearance: the jet engine is mounted in the tail like a DC-10/MD-11. The low wings are straight and have winglets at the end. The windows look like those on the Piper Malibu.
