Fossett made the first solo nonstop unrefueled fixed-wing aircraft flight around the world between February 28 and March 3, 2005. He took off from Salina, Kansas, where he was assisted by faculty members and students from Kansas State University, and flew eastbound with the prevailing winds, returning to Salina after 67 hours, 1 minute, 10 seconds, without refueling or making intermediate landings. His average speed of 342.2 mph (550.7 km/h) was also the absolute world record for "speed around the world, nonstop and non-refueled."
