Helicopter circumnavigation flight

In 1982, H. Ross Perot and Jay Colburn completed the first circumnavigation of the world in a helicopter, the Spirit of Texas. Their journey began 29 days, 3 hours, and 8 minutes earlier on September 1. For their trip around the world, which began and ended in Fort Worth, Texas, Perot and Coburn flew a Long Ranger with full navigation equipment, survival gear, and emergency items. Pop-out floats were added, and a 151-gallon auxiliary fuel tank in place of the rear seat was used to enable the Spirit of Texas to fly eight hours without refueling. An Allison 250-C28B turbine engine performed flawlessly for 246.5 hours of flight, flying more than 10 hours a day, over open ocean, barren desert, and tropical rain forest with an average ground speed of 117 mph.
