The Flying Hotel and The Largest Helicopter in The World.
This "Hotelicopter" is modeled on the Soviet-made Mil V-12, of which there were only 2 Prototypes ever made.
The Hotelicopter Company purchased one of these prototypes from the Mikhail Leontyevich Mil Helicopter Plant in Panki-Tomilino, Russia in 2004 and have been engineering the World's First Flying Hotel ever since.
