The Scaled Composites Model 311 Virgin Atlantic GlobalFlyer ( registered N277SF) is an aircraft designed by Burt Rutan in which Steve Fossett first flew a solo nonstop airplane flight around the world in slightly more than 67 hours (2 days 19 hours) in 2005. The flight speed of set the world record for the fastest nonstop non-refueled circumnavigation, beating the mark set by the previous Rutan-designed

Design and construction

The GlobalFlyer was specifically designed to make an uninterrupted (non-refueled) circumnavigation of the globe with a single pilot. Unusual for a modern civil aircraft, the GlobalFlyer has only a single jet engine. The GlobalFlyer has twin tail booms mounted outboard of a shorter central fuselage

honeycomb. The use of lightweight materials permits the fuel (in 13 tanks) to compose 83% of the take-off weight. The aircraft had an estimated lift-to-drag ratio of 37. The aerodynamic drag is so low that, even with the engine idling, the aircraft can only descend at a maximum of . Twin drogue parachutes were used to slow the GlobalFlyer to landing speeds. The earlier Voyager aircraft structure had been by necessity built so lightly that it significantly deflected under aerodynamic loading.

. A design using a single jet engine was chosen for the GlobalFlyer for increased reliability over piston engines and faster circumnavigation for the solo pilot. The GlobalFlyer is designed to operate at high altitudes, where the air is colder, yet in-tank fuel heaters were not included in its design. There was some concern that the fuel might freeze if the aircraft used standard jet fuel. Therefore, the GlobalFlyer's

in Salina, Kansas, where a recently resurfaced runway of would accommodate the anticipated long takeoff roll. The circumnavigation attempt was delayed until 28 February 2005 to obtain a weather forecast with low turbulence for the fragile GlobalFlyer and good tailwinds. Mission Control was at the Salina campus of Kansas State University, located adjacent to the Salina Municipal Airport. A tailwind was essential to making the that it needed to fly to meet the FAI’s definition of circumnavigation, the length of the

As it turned out, a design flaw in the fuel venting system resulted in the loss of about of fuel early in the flight.

near Japan. Fossett chose to delay the final decision until he reached Hawaii. By that time, favorable winds encouraged the mission team to attempt to complete the circumnavigation. GlobalFlyer landed at Salina at 19:50 UTC (13:50 CST) on 3 March 2005, having completed its circumnavigation in 2 days, 19 hours, 1 minute and 46 seconds. , this is the fastest world trip in its class at a speed of . The distance flown was determined to be , only above the minimum distance required.

Generator failure meant that Fossett had about 25 minutes until his batteries were exhausted, when he would have lost all electrical power. To add to the drama, ice on the inside of the canopy made vision difficult, with his landing being made virtually blind; one tire was flat from the takeoff roll and the remaining main tire burst on touchdown due to frozen brakes; and the fuel remaining was indicated to be only . The aircraft survived the landing, with minor damage including a broken aileron hinge and a jammed intake valve.


Closed-circuit distance flight and retirement

Fossett flew the GlobalFlyer to one more major aviation record: the absolute distance over a closed circuit. A closed-circuit record must take off and land at the same place, and the distance is measured over verifiable waypoints. Dick Rutan and
