It was a civilian model that had dual P&W PT6 turbines and a Winnebago interior. It was the ultimate RV and had a price to reflect that fact. It cost upwards of a million dollars.

There are lot of helicopters that are, shall we be kind, beauty challenged. Those are the ones that inspired the cracks about "helicopters don't fly, they're so ugly that the Earth repells them." However, there are some choppers that are truly beautiful. Any helicopter that is med-evacing someone to a hospital is beautiful. All hlicopters that rescue people from sinking ships, enemy fire, floods, etc. are beautiful. Even an Apache can be beautiful if it blows apart the enemy tank that's homing in on your position. And a Rotorway Exec 163 is indeed a thing of beauty ( http://www.rotorway.com ).

To my mind, the Supermarine Spitfire is just about as beautiful as any plane can be. A Concorde or SR-71 is pretty but sterile by comparison to a Spitfire. It never ceases to amaze me that a country that built some of the ugliest flying machines ever known to man (e.g Lysanders and Buccaneers) could also build the most beautiful. I watched "Battle of Britian" again last night and just was amazed at the wonder of those Spitfires.

Years ago, I read a book by a General Pyle, the commander of the British anti-aircraft forces in WWII. He had a saying that went "It is said that the British anti-aircraft gunner can recognize three types of aircraft: approaching and considered hostile, receeding and considered friendly, and Lysanders." If you ever saw a Lysander, you'll see how even British anti-aircraft gunners could recognize a plane so distinctively ugly. However, if I were a downed airman or French Resistance agent being smuggled out of Nazi territory, I'll bet even a Lysander would look beautiful under the circumstances.
