"... as a breathtaking stunt performer and became, by wide consensus, an American aviation legend, died on Tuesday in Los Angeles. He was 94.... Even General Yeager, perhaps the most famous test pilot of his generation, was humbled by Mr. Hoover, describing him... as 'the greatest pilot I ever saw.' The World War II hero Jimmy Doolittle, an aviation pioneer of an earlier generation, called Mr. Hoover 'the greatest stick-and-rudder man that ever lived.'... Mr. Hoover’s trademark maneuver on the show circuit was a death-defying plunge with both engines cut off; he would use the hurtling momentum to pull the plane up into a loop at the last possible moment."
