Two Broken Ribs and a Broom Handle
On the evening of Sunday, October 12, 1947, a twenty-four-year-old Army Air Forces captain named Chuck Yeager had dinner with his wife, Glennis, at Pancho Barnes's ranch and bar on the edge of the Mojave Desert. Afterwards the couple went riding. It was a dark night, they were racing, and Yeager's horse hit a closed gate. He was thrown, knocked out, and came to with two cracked ribs.
The injury was a serious problem. Two days later he was scheduled to fly the Bell XS-1, a small orange rocket plane shaped like a .50-calibre bullet, in an attempt to go faster than the speed of sound. Nobody had done it and been sure of it. The British test pilot Geoffrey de Havilland Jr. had died the previous year when his jet broke up near transonic speed. If the flight surgeon learned about the ribs, Yeager would be grounded and the flight postponed.
So he had a civilian doctor in nearby Rosamond tape him up, and he told only one person on the project, the engineer Jack Ridley. The difficulty was the hatch. To seal himself into the XS-1 after climbing down into it from the bomb bay of a B-29, the pilot had to lift the door into place and slam down a heavy locking lever, which needed the use of his right side. Yeager could not do it. Ridley went into the hangar, sawed about ten inches off a broom handle, and showed him how to use it as an extension so that he could push the lever home with his left hand.
On the morning of October 14, the ground crew presented Yeager with a carrot, a pair of glasses and a length of rope, jokes about the horse. Then the B-29 climbed to more than 20,000 feet over Rogers Dry Lake and dropped him. Yeager lit the rocket chambers, climbed above 40,000 feet, and watched the needle on his Machmeter stall at 0.965, then jump off the scale. On the ground, people heard a boom roll across the desert.
The radio channel was not secure and the programme was classified, so he could not simply announce it. Instead he called Ridley. "Make another note," he said, according to his own later account. "There's something wrong with this Machmeter. It's gone completely screwy!" Ridley, understanding exactly what he meant, told him he was probably seeing things.

The Mud River
Charles Elwood Yeager was born on February 13, 1923, in Myra, West Virginia, a tiny community on the Mud River about forty miles southwest of Charleston. His parents, Albert Hal Yeager and Susie Mae Sizemore, farmed, and his father drilled for natural gas. The family name was an anglicised form of the German Jäger, meaning hunter. Yeager had two brothers and two sisters; one sister, Doris Ann, was killed as a toddler when his older brother Roy, then four, was playing with a gun. When Chuck was five the family moved to Hamlin, a nearby village of a few hundred people.
The hill country shaped him. He hunted from boyhood and became a superb shot; his vision was later rated at 20/10. He was good with his hands and learned mechanics from his father, including how to handle explosives on the gas wells. He was not much of a scholar. At Hamlin High School he played basketball and football, and his best grades came in geometry and typing. In his 1985 autobiography, written with Leo Janos, he described himself as the kid who swam the Mud River with a stolen watermelon and shot the head off a squirrel before breakfast.
He had no particular interest in aeroplanes. His first taste of military life came in the summers of 1939 and 1940 at a Citizens Military Training Camp in Indiana. He graduated from high school in June 1941, and on September 12 of that year, at eighteen, he enlisted as a private in the Army Air Forces. The service trained him as an aircraft mechanic and sent him to Victorville, California.
The Flying Sergeant
At enlistment Yeager was not eligible for pilot training. He was too young and lacked the two years of college the Army Air Forces then required. Pearl Harbor changed that. The service suddenly needed far more pilots than the colleges could supply, and in 1942 it opened a programme that allowed enlisted men without degrees to train as pilots. Yeager, then a crew chief on an AT-11 trainer, was accepted in July 1942.
He found that he had a gift for it. His eyesight let him spot other aircraft well before his instructors did, and his mechanical training meant that he understood what the machine was doing beneath him. He earned his wings at Luke Field, Arizona, on March 10, 1943, and was appointed a flight officer, the rank then given to enlisted men who graduated from pilot training. During his training in California he met Glennis Dickhouse, a young woman from Oroville.
He was assigned to the 363rd Fighter Squadron of the 357th Fighter Group, which trained on Bell P-39 Airacobras in Nevada. He was grounded for a week for clipping a farmer's tree during a low training flight. In November 1943 the group shipped out to RAF Leiston in Suffolk, England, where it converted to the North American P-51 Mustang and began escorting American bombers over Germany. Yeager named his Mustang after his girlfriend; by the end of the war its successors carried the name Glamorous Glen.
Shot Down Over France
Yeager scored his first victory, a Messerschmitt Bf 109, in early March 1944. On March 5, on only his eighth mission, he was shot down over southwestern France. He bailed out of his burning Mustang, was wounded, and was picked up by the Maquis, the French Resistance.
He spent weeks with the resistance fighters, and the skills he had learned from his father turned out to be useful. He helped the group build bombs, though he did not take part in combat. Then the Resistance moved him toward the Pyrenees. Crossing the mountains into Spain with another American airman, a navigator named Omar "Pat" Patterson, who had been badly wounded, Yeager helped him through the snow. He reached Spain on March 30, 1944, and was back in England by May 15. He was later awarded the Bronze Star for helping Patterson.
Under Allied policy, airmen who had evaded capture with the help of resistance networks were not allowed to fly over enemy territory again. If they were shot down a second time and captured, they might betray the people who had sheltered them. Yeager and a fellow evader, Fred Glover, refused to accept being sent home. On June 12, 1944, they made their case directly to General Dwight D. Eisenhower, the Supreme Allied Commander. After the Normandy landings the resistance networks in France were coming into the open anyway, and Eisenhower, after obtaining permission from the War Department, allowed them to return to combat.
Yeager made the most of it. On October 12, 1944, leading his squadron as an escort, he came up behind a formation of more than twenty Bf 109s and shot down five of them in a single mission, becoming the first pilot in his group to be an ace in a day. Two of the victories came without firing a shot, when German pilots panicked as he closed in, one of them colliding with his wingman. In November he shot down a Messerschmitt Me 262, the German jet fighter, as it came in to land. By the time he flew his sixty-first and last mission, on January 15, 1945, he had been commissioned and promoted to captain and was credited with 11.5 victories.
His memoir is candid about the ugly parts of the war. He recalled a mission on which Eighth Air Force orders were to strafe anything that moved, and wrote that he was not proud of it. He returned to the United States in February 1945. On February 26 he married Glennis.
Boyd's Instinctive Pilot
Because he had evaded capture, Yeager was allowed to choose his next posting. With Glennis pregnant, he asked for Wright Field in Dayton, Ohio, which was close to home. It turned out to be the centre of American flight testing. His large number of flying hours and his maintenance background qualified him as a functional test pilot, checking out repaired aircraft, and that brought him under the command of Colonel Albert Boyd, the demanding head of the Flight Test Division, who is often called the father of modern flight testing.
Boyd noticed him. Yeager was one of the least educated pilots in the division and was sometimes treated as a hillbilly by officers who looked down on his accent. But he could fly anything, and he could describe precisely what an aircraft was doing. He was sent to the test pilot school at Wright Field and graduated in 1946, later saying that the instructors had taken mercy on his academics because of his flying.
In 1947 the Army Air Forces and the National Advisory Committee for Aeronautics were both trying to penetrate the so-called sound barrier. As aircraft approached the speed of sound, shock waves formed on the wings and control surfaces, causing violent buffeting and loss of control. Several pilots had died in dives near that speed, and some engineers doubted a piloted aircraft could pass through it intact. Bell Aircraft had built the XS-1 for the purpose: a rocket plane with thin, straight wings and a fuselage modelled on the shape of a bullet, which was known to be stable at supersonic speeds. It would be carried aloft by a
Boeing B-29 and dropped, since it could not carry enough fuel to take off and climb on its own.
Bell's civilian test pilot, Chalmers "Slick" Goodlin, had flown the aircraft at subsonic speeds. According to widely repeated accounts, he asked for a large bonus, reportedly $150,000, to take it to Mach 1. The Army Air Forces decided to run an accelerated programme with its own pilots instead. In June 1947 Boyd picked Yeager, one of his most junior test pilots, as the primary pilot. Boyd considered him the best instinctive pilot he had ever seen, and he valued the young captain's ability to stay calm and focused under stress. Bob Hoover, another talented young pilot, was named as backup. Ridley, an engineer from Oklahoma with a master's degree in aeronautical engineering, would run the technical side.
Yeager would fly the XS-1 on his ordinary captain's pay, which was a few hundred dollars a month.
Point Nine Nine Seven
The team assembled at Muroc Army Air Field, on the dry lake beds of the Mojave, in late July 1947. Yeager made his first glide flight on August 6 and his first powered flight on August 29, reaching Mach 0.85. He named the aircraft Glamorous Glennis.
The programme advanced by small steps. On each flight Yeager pushed a little faster, about two hundredths of a Mach number at a time, and reported the results to Ridley, who analysed the data and set the next target. As the speed crept above Mach 0.9, the buffeting worsened and the aircraft pitched sharply up and down.
On October 10, on his eighth powered flight, Yeager reached Mach 0.997 and lost pitch control. A shock wave had formed along the hinge line of the elevator, the movable flap on the tail that pilots used to raise or lower the nose, and the elevator stopped working. Pressing on without control would have been reckless, so he shut down and glided home.
Ridley's solution made the record possible. The XS-1 had been designed with a horizontal stabiliser whose whole angle could be adjusted, a feature intended for trimming the aircraft rather than for flying it. Ridley reasoned that by moving the entire stabiliser in tiny increments, Yeager could control the aircraft's pitch even when the elevator was useless. Nobody had tried it at that speed. Yeager agreed to try it on the next flight. Two days later came the horse, the ribs and the broom handle.
On October 14 the stabiliser worked as Ridley had predicted. Yeager's formal pilot report was dry.
At this indication, the meter momentarily stopped and then jumped up to 1.06, and the hesitation was assumed to be caused by the effect of shock waves on the static source.
— Chuck Yeager, XS-1 pilot report, October 14, 1947
Decades later, writing for Popular Mechanics, he described the moment more vividly.
There was no buffet, no jolt, no shock. Above all, no brick wall to smash into. I was alive.
— Chuck Yeager, Popular Mechanics, 1987
The Secret and the Record
The flight was classified. The Air Force, which had become an independent service a month before, did not publicly confirm the achievement until June 10, 1948. By then Yeager had flown supersonic many times. Over the following years he made dozens of flights in the XS-1, reaching the aircraft's top speed of about Mach 1.45 in March 1948, and on January 5, 1949, he made the only ground takeoff of an X-series rocket plane, climbing from the lake bed to supersonic speed in under two minutes.
The record did not go unchallenged in the history books. Some historians believe that George Welch, a North American Aviation test pilot, may have exceeded Mach 1 in a dive in the prototype XP-86 Sabre around the same time, although instrumentation to confirm it was lacking. Yeager's flight is the one generally accepted as the first confirmed supersonic flight in level flight by a piloted aircraft. In 1948 he received the Collier Trophy and the Mackay Trophy for it.
He stayed at Muroc, renamed Edwards Air Force Base in 1949, as the leading military test pilot of his generation. In 1953 he flew a MiG-15 that a North Korean pilot, No Kum-sok, had flown to South Korea when he defected, helping to evaluate the Soviet fighter. That year he also flew chase for the aviator Jacqueline Cochran when she became the first woman to break the sound barrier.
Late in 1953 Yeager and Ridley set their sights on a new target. On November 20 the Navy's test pilot Scott Crossfield had reached Mach 2 in the Douglas D-558-II Skyrocket. The Air Force team wanted the record back in time for the fiftieth anniversary of the Wright brothers' first flight. On December 12, 1953, in the Bell X-1A, Yeager reached Mach 2.44.
Then the aircraft went out of control. At about 80,000 feet it began rolling, pitching and yawing all at once, a phenomenon called inertia coupling that was barely understood at the time. Yeager was thrown around the cockpit and fell about 51,000 feet in less than a minute before he regained control, at about 29,000 feet, and landed. He was awarded the Distinguished Service Medal. The episode is a reminder of what test flying meant in the 1950s: the pilots were often the first people to discover the physics.
Commander
Yeager was primarily a fighter pilot, and in 1954 he left Edwards to command squadrons. From 1954 to 1957 he led an F-86H Sabre squadron based in West Germany and France, and from 1957 to 1960 an F-100 squadron based in California and Spain. He then attended the Air War College.
In 1962 he returned to Edwards as the first commandant of the USAF Aerospace Research Pilot School, which trained military test pilots to become astronauts. The irony was obvious. With only a high school education, Yeager was not eligible to become an astronaut himself, and he was known to be dismissive of the early Mercury capsules, in which the pilot had little to do. His time at the school was also marked by a lasting controversy. Ed Dwight, the first African American candidate admitted to the programme, later described discriminatory treatment during his training there and blamed Yeager's leadership. Yeager, in his autobiography, denied acting out of racial prejudice and said that Dwight struggled with the academic work. The competing accounts have never been fully reconciled.
On December 10, 1963, Yeager took a rocket-boosted Lockheed NF-104A, one of the school's modified Starfighters, on an attempt at an altitude record. After climbing to more than 100,000 feet, the aircraft's controls became ineffective and it entered a flat spin. He fell for tens of thousands of feet before ejecting. As he separated from the seat, it struck him; the still-hot rocket motor broke his helmet's faceplate and set his emergency oxygen supply alight. He was badly burned on the face and neck and needed long, painful treatment. Some fellow pilots argued that he had not flown the demanding climb profile precisely. It was the last time he tried for a record.
He went to war again. In 1966 he took command of the 405th Tactical Fighter Wing at Clark Air Base in the Philippines, whose squadrons rotated through Southeast Asia, and flew 127 missions over Vietnam. In 1968 he commanded the 4th Tactical Fighter Wing, flying F-4 Phantoms, and led it to South Korea during the crisis that followed North Korea's seizure of the USS Pueblo. He was promoted to brigadier general in 1969. From 1971 to 1973 he served as the American air attaché in Pakistan, advising the Pakistan Air Force, and remained there during the 1971 war with India.
He retired from the Air Force on March 1, 1975, a date he chose because of its resemblance to "Mach 1". He had spent more than thirty years on active duty and fought in three wars.
The Right Stuff
Retirement made Yeager far more famous than the sound barrier had. In 1979 Tom Wolfe published The Right Stuff, his book about the test pilots of Edwards and the first American astronauts. Wolfe used Yeager as the book's touchstone, the pilot against whom all the others measured themselves, and described the laconic West Virginia drawl that airline pilots across the country had come to imitate. The New York Times, in its obituary of Yeager, quoted Wolfe's description of him.
the most righteous of all the possessors of the right stuff
— Tom Wolfe, The Right Stuff, 1979
The 1983 film adaptation, in which Sam Shepard played Yeager, opens with the XS-1 flight and closes with the NF-104 crash. Yeager appeared in a small role as a bartender at Pancho's, and joked that he had spent more hours there than in the cockpit. The film made him a household name.
He used the fame. His autobiography,
Yeager, published in 1985, became a bestseller. For several years in the 1980s he was the public face of ACDelco, General Motors' parts division, and he drove the pace car at the Indianapolis 500. He served as technical adviser to a series of flight simulator games from
Electronic Arts;
Chuck Yeager's Advanced Flight Trainer was the company's best-selling game of 1987. President Ronald Reagan awarded him the Presidential Medal of Freedom in 1985 and the following year appointed him to the Rogers Commission that investigated the Challenger disaster. Congress had already awarded him a special silver medal in 1976 for the XS-1 flight.
He kept flying for decades. Working with Piper, he set speed records in light aircraft. On October 14, 1997, the fiftieth anniversary of his flight, he broke the sound barrier again in an F-15, with Bob Hoover flying chase. On the sixty-fifth anniversary, in 2012, at eighty-nine, he rode as co-pilot in an F-15 that went supersonic over Nevada.
The Last Flight Home
Glennis Yeager died of ovarian cancer in December 1990. The couple had four children and had settled in Grass Valley, California, after he retired. In 2003 Yeager married Victoria Scott D'Angelo, whom he had met on a hiking trail. His marriage led to a bitter legal dispute with his children over his finances; in 2008 a California appeals court ruled in Yeager's favour, finding that his daughter had breached her duties as trustee of his assets.
In his later years he became an unfiltered presence on Twitter, answering questions about his career and offering blunt opinions. He also chaired the Experimental Aircraft Association's Young Eagles programme, which offers free flights to young people, from 1994 to 2004.
Chuck Yeager died in a Los Angeles hospital on December 7, 2020, at the age of ninety-seven. It was the seventy-ninth anniversary of the attack on Pearl Harbor, the event that had opened pilot training to an enlisted mechanic without a college education.
Yeager's legacy is sometimes flattened into the image of the fearless, gum-chewing cowboy that Wolfe and Hollywood created. The record shows something more useful. His famous flight rested on weeks of incremental testing, on a trusted engineer's solution to a control problem, and on a pilot who understood his machine well enough to know which risks were worth taking. He survived being shot down, a flat spin at supersonic speed, an ejection in flames and three wars, and he lived to a very old age in a profession that killed many of his friends. For all the bravado of his public image, the core of his skill was careful, repeatable judgement in the air.
