The success was bittersweet, however, as the ultimate goal was to break the speed record over a 3 km closed course set in 1989 by Lyle Shelton in Rare Bear — a Grumman F8F-2 Bearcat. The FAI retired Shelton’s record after the organization made changes in the sporting code. While Hinton’s speed was slightly quicker than Shelton’s, had the rules not changed the record would have to beat by 1 percent, translating to 533 mph.
