Sabreliner Demo at the 2013 Reno Air Races

Bob Hoover is best known for his civil air show career, which started when he was hired to demonstrate the capabilities of Aero Commander's Shrike Commander, a twin piston-engined business aircraft which had developed a rather staid reputation due to its bulky shape. Hoover showed the strength of the plane as he put the aircraft through rolls, loops, and other maneuvers which most people would not associate with executive aircraft. As a grand finale, he shut down both engines and executed a loop and an eight-point hesitation slow roll as he headed back to the runway. He touched down on one tire, then the other, before landing. After pulling off the runway, he would start engines to taxi back to the parking area. On airfields with large enough parking ramps (such as the Reno Stead Airport where the Reno Air Races take place), Hoover would sometimes land directly on the ramp and coast all the way back to his parking spot in front of the grandstand without restarting the engines.
A few years after starting the show he began carrying passengers during the show. (The Shrike Commander carries six passengers.) These passengers became known as "Hoover's Heavers" due to the number who became airsick during the maneuvers.[citation needed]
With the advent of camcorders Hoover added a flourish to the act by pouring a glass of iced tea from a pitcher, while performing a barrel roll, a 1G maneuver.[15]
Hoover also served for many years as the official starter of the Unlimited-class races at the Reno Air Races. The race planes (mostly modified World War II fighter aircraft) joined up in line-abreast formation on Hoover's yellow P-51 Mustang, and when in satisfactory order the spectators would hear over the PA his famous radio call, "Gentlemen, you have a race." Hoover's plane would pull up sharply into a vertical climb as the racers dove toward the first turn. Hoover would circle overhead during the race, ready to assist any race pilots with problems. In several cases Hoover helped pilots with crippled race planes to a safe recovery by talking them down while flying in formation with them.
