Voyager, the first aircraft to fly around the world without refueling, was greeted by about 200 spectators as it arrived on a 130-foot flatbed truck at the Experimental Aircraft Assn. in Oshkosh, Wis. The Mojave-based aircraft, which circled the globe in December during a 26,000-mile, nine-day flight, will be on display at the association’s annual Fly-In and Convention, July 31 to Aug. 7. Designer Burt Rutan and pilots Dick Rutan and Jeana Yeager also will appear at the convention. After the convention, the propeller-driven aircraft will make its final trip by truck to the Smithsonian Institution in Washington, where it will be on permanent display. It may stop at an air show in Cleveland on the way, officials said.
