The 747-8 is one of Boeing´s most successful models. An unnamed client has customized his private plane with luxuries such as fully equipped bathrooms, private living room, a master suite with stunning views, a guest cabin with en-suite bathroom, and a private office. Other amenities include big screen TVs, low tables, two living areas with sofas, dining room for 14 guests, and a large meeting room. The client spent about $200 million for the facilities. No wonder the plane finds a place in our list of most expensive planes. This amazing aircraft can hit a speed of about 645 miles per hour on a 9,200-mile flight.
