Best of the Best 2011: Business Aircraft: Large: Gulfstream G450

    The cabin of the Gulfstream G450 (912.965.3000, www.gulfstream.com) is the same height and width as that of the larger G550, and it affords the same Gulfstream-signature oval windows that provide an abundance of natural light. Other features that contribute to an enjoyable flight include an air-circulation system that continuously supplies fresh air to the cabin and as many as six lie-down sleeping berths. The $39.9 million G450 flies 5,000 miles nonstop, cruises at nearly 530 mph, and seats as many as 16 passengers.
