Bob Hoover, a pilot who escaped Nazi captivity in a stolen plane, tested supersonic jets with his friend Chuck Yeager, barnstormed the world as a breathtaking stunt performer and became, by wide consensus, an American aviation legend, died on Tuesday in Los Angeles. He was 94.
His death was confirmed by Ron Kaplan of the National Aviation Hall of Fame in Dayton, Ohio, where Mr. Hoover was enshrined in 1988.
Even General Yeager, perhaps the most famous test pilot of his generation, was humbled by Mr. Hoover, describing him in the foreword to Mr. Hoover’s 1996 autobiography, “Forever Flying,” 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.”
Tall and lanky, Mr. Hoover forged a long career studded with aeronautical achievements and feats of derring-do. The subtitle of his memoir, written with Mark Shaw, suggests as much: “Fifty Years of High-Flying Adventures, From Barnstorming in Prop Planes to Dogfighting Germans to Testing Supersonic Jets.”
At a World War II air base in the Mediterranean, he wrote, he terrified senior pilots who had been lording it over him by flying a P-40 fighter under a bridge while they were standing on it. At an international aerobatic competition in Moscow in 1966, he put on a thrilling though unauthorized display, flying upside down and executing spectacular loops in a Yakovlev-18.
By his account, the stunt upset his Soviet hosts, and he escaped K.G.B. custody afterward only because of the intervention of a mildly inebriated Yuri Gagarin, the first man in space. The two had struck up a friendship.
Indeed, Mr. Hoover could trace the history of aviation, to the dawn of the space age, by the men he came to know: Orville Wright and Charles Lindbergh, General Doolittle and the World War I flying ace Eddie Rickenbacker, and the astronauts Walter Schirra and Neil Armstrong as well as General Yeager and Colonel Gagarin.
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.
But his stunts were not foolhardy. Each involved painstaking preparation and rational calculation of risk. “A great many former friends of mine are no longer with us simply because they cut their margins too close,” he once said.
Mr. Kaplan, of the National Aviation Hall of Fame, said of Mr. Hoover, “You do not survive the life he lived without discipline and caution.”
His favorite plane in the 1950s and ’60s was “Old Yeller,” a P-51 Mustang fighter painted bright yellow. Mr. Hoover sometimes shunned flight suits to perform in a business suit (less trouble for the undertaker in case of an accident, he once said) and a trademark Panama straw hat.
He once invited a crew from the ABC program “That’s Incredible!” to film him in action, pouring a glass of iced tea with one hand while he rolled his plane 360 degrees with the other.
Robert Anderson Hoover was born on Jan. 24, 1922, in Nashville. His father, Leroy, worked for a paper company while his mother, Bessie, kept house. Bob started to fly as a teenager, “working 16 hours in a grocery store to earn 15 minutes of flight time,” as he told an audience of young admirers.
He soon taught himself the loops and hand rolls of aerobatics, enlisted in the Tennessee National Guard and received orders to Army Pilot Training School.
With the onset of World War II, he was sent to England as a flight instructor for the Royal Air Force. The Army Air Forces later assigned him to Casablanca, Morocco, where he tested newly assembled and repaired planes and ferried them to the front. Valued as an operations officer, he was nevertheless hungry to fight and, through persistence, persuaded his commanders to grant him combat duty.
“I can hit a target upside down or right side up,” he said he told a general.
As a pilot with the 52nd Fighter Group, based in Corsica, Mr. Hoover, a lieutenant, flew 58 successful missions before his Spitfire fighter was shot down by the Luftwaffe in February 1944. He spent 16 months in Stalag Luft I, a prisoner of war camp in Germany reserved for Allied pilots.
Mr. Hoover and a friend escaped from the camp in the chaotic final days of the war, according to his memoir. Commandeering an aircraft from a deserted Nazi base, they flew it to freedom in the newly liberated Netherlands, only to be chased by pitchfork-wielding Dutch farmers enraged by the plane’s German markings.
He remained in the military after the war as a test pilot based at Wilbur Wright Field in Ohio (now part of Wright-Patterson Air Force Base). There, with jet-propulsion planes replacing propeller aircraft, he took on the dangerous duty of working out kinks in workhorses like the F-80 and P-51 fighters.
Mr. Yeager was also a test pilot there, and in the fall of 1945 they became friends after getting into a spontaneous mock dogfight that ended in a draw. They were soon performing in air shows around the country.
Both men were recruited to train together at Muroc Field (later named Edwards Air Force Base) in California to fly the Bell Aircraft X-1, the jet that broke the sound barrier in October 1947 over the Mojave Desert.
Mr. Hoover might well have gotten the call to pilot the plane if his rambunctious streak had not undone him, Mr. Kaplan said. Earlier that year, he had buzzed a civilian airport in Springfield, Ohio, in an experimental military jet as a favor to a friend; the friend wanted his relatives in the area to think that he was flying the aircraft.
Commanders discovered the episode, and Mr. Hoover was relegated to flying the “chase” plane during the X-1 test flights, making observations and taking photographs, while Mr. Yeager made history.
After leaving the Air Force (the successor to the Army Air Forces), Mr. Hoover became a test pilot for General Motors and then North American Aviation, a Los Angeles-based military contractor that later merged with Rockwell International.
He stayed with the company through the 1980s. But as the pace of jet innovation slowed, he became a roving ambassador and showman, flying North American planes at air shows around the world and taking part in a documentary film, “Flying the Feathered Edge: The Bob Hoover Project.”
Mr. Hoover was one of the most honored pilots in American history. His military awards alone include the Distinguished Flying Cross, the Soldier’s Medal of Valor, the Air Medal with Clusters, the Purple Heart and the French Croix de Guerre. In 2007 he received the National Air and Space Museum Trophy, the museum’s highest honor.
Mr. Hoover’s wife, Colleen, died recently. They had lived for many years in the Los Angeles area. Survivors include a son, a daughter and several grandchildren.
Mr. Hoover flew well into his 80s, but not before clashing with the authorities when he was 72, in 1994, when medical examiners from the Federal Aviation Administration declared him unfit to fly, saying that his “cognitive abilities” had diminished.
Mr. Hoover quickly recertified himself in Australia and began a legal battle back home, led by the defense lawyer F. Lee Bailey, who had befriended Mr. Hoover through a mutual love for flying helicopters.
Mr. Hoover emerged victorious 18 months later, and his United States license was restored. His campaign found support among fans who wrote thousands of letters. At the Oshkosh Fly-In and Air Show in Wisconsin, posters were displayed everywhere saying, “Let Bob Fly.”
