The Beech Starship is one of the most distinctive business aircraft ever built. It was also one of the first aircraft to utilize composites in the air frame. The rear mounted, pusher props made the interior of the aircraft very quiet. However, pusher props meant the props operated in turbulent air behind the wings. This resulted in an unusually loud, buzzing external sound, as anyone who has ever heard one can testify to. Sadly, excessive operating costs made the plane unpopular and only 85 were built.
