The Beechcraft (Raytheon-Beech 2000) Starship is a Burt Rutan design. Like all of his designs, it differs from the expected configuration. I've searched many an airport for signs of one and finally found one in Punta Gorda, FL. The linked web page has lots of great pictures and says that the existing planes are due to be decommisioned by Raytheon, which owns all but four of the flying planes.
