How two pilots, Dick Rutan and Jeana Yeager, became the first to fly non-stop around the world without refuelling in December 1986. Their experimental aircraft was designed by Dick's brother, Burt Rutan. It had to be incredibly light to carry the huge weight of fuel required. But that meant the plane was vulnerable to breaking up in turbulence. Dick Rutan and Jeana Yeager endured storms and equipment malfunctions to set the world record. They spent 9 days, 3 minutes and 44 seconds in the air. Alex Last speaks to Dick Rutan about their achievement.
