When the wind blew the few inches of water back and forth across the lake beds, they became absolutely smooth and level. And when the water evaporated in the spring, and the sun baked the ground hard, the lake beds became the greatest natural landing fields ever discovered, and also the biggest, with miles of room for error. That was highly desirable, given the nature of the enterprise at Muroc.

Besides the wind, sand, tumbleweed, and Joshua trees, there was nothing at Muroc except for two quonset-style hangars, side by side, a couple of gasoline pumps, a single concrete runway, a few tarpaper shacks, and some tents. The officers stayed in the shacks marked "barracks," and lesser souls stayed in the tents and froze all night and fried all day. Every road into the property had a guardhouse on it manned by soldiers. The enterprise the Army had undertaken in this godforsaken place was the development of supersonic jet and rocket planes.

At the end of the war the Army had discovered that the Germans not only had the world's first jet fighter but also a rocket plane that had gone 596 miles an hour in tests. Just after the war a British jet, the Gloster Meteor, jumped the official world speed record from 469 to 606 in a single day. The next great plateau would be Mach 1, the speed of sound, and the Army Air Force considered it crucial to achieve it first.

The speed of sound, Mach 1, was known (thanks to the work of the physicist Ernst Mach) to vary at different altitudes, temperatures, and wind speeds. On a calm 60-degree day at sea level it was about 760 miles an hour, while at 40,000 feet, where the temperature would be at least sixty below, it was about 660 miles an hour. Evil and baffling things happened in the transonic zone, which began at about.7 Mach. Wind tunnels choked out at such velocities. Pilots who approached the speed of sound in dives reported that the controls would lock or "freeze" or even alter their normal functions. Pilots had crashed and died because they couldn't budge the stick. Just last year Geoffrey de Havilland, son of the famous British aircraft designer and builder, had tried to take one of his father's DH 108s to Mach 1. The ship started buffeting and then disintegrated, and he was killed. This led engineers to speculate that the shock waves became so severe and unpredictable at Mach 1, no aircraft could survive them. They started talking about "the sonic wall" and "the sound barrier."

So this was the task that a handful of pilots, engineers, and mechanics had at Muroc. The place was utterly primitive, nothing but bare bones, bleached tarpaulins, and corrugated tin rippling in the heat with caloric waves; and for an ambitious young pilot it was perfect. Muroc seemed like an outpost on the dome of the world, open only to a righteous few, closed off to the rest of humanity, including even the Army Air Force brass of command control, which was at Wright Field. The commanding officer at Muroc was only a colonel, and his superiors at Wright did not relish junkets to the Muroc rat shacks in the first place. But to pilots this prehistoric throwback of an airfield became… shrimp heaven! the rat-shack plains of Olympus!

Low Rent Septic Tank Perfection… yes; and not excluding those traditional essentials for the blissful hot young pilot: Flying & Drinking and Drinking & Driving.

Just beyond the base, to the southwest, there was a rickety wind-blown 1930's-style establishment called Pancho's Fly Inn, owned, run, and bartended by a woman named Pancho Barnes. Pancho Barnes wore tight white sweaters and tight pants, after the mode of Barbara Stanwyck in Double Indemnity. She was only forty-one when Yeager arrived at Muroc, but her face was so weatherbeaten, had so many hard miles on it, that she looked older, especially to the young pilots at the base. She also shocked the pants off them with her vulcanized tongue. Everybody she didn't like was an old bastard or a sonofabitch. People she liked were old bastards and sonsabitches, too. "I tol' 'at ol' bastard to get 'is ass on over here and I'd g'im a drink." But Pancho Barnes was anything but Low Rent. She was the granddaughter of the man who designed the old Mount Lowe cable-car system, Thaddeus S. C. Lowe. Her maiden name was Florence Leontine Lowe. She was brought up in San Marino, which adjoined Pasadena and was one of Los Angeles' wealthiest suburbs, and her first husband—she was married four times—was the pastor of the Pasadena Episcopal Church, the Rev. C. Rankin Barnes. Mrs. Barnes seemed to have few of the conventional community interests of a Pasadena matron. In the late 1920's, by boat and plane, she ran guns for Mexican revolutionaries and picked up the nickname Pancho. In 1930 she broke Amelia Earhart's air-speed record for women. Then she barnstormed around the country as the featured performer of "Pancho Barnes's Mystery Circus of the Air." She always greeted her public in jodhpurs and riding boots, a flight jacket, a white scarf, and a white sweater that showed off her terrific Barbara Stanwyck chest. Pancho's desert Fly Inn had an airstrip, a swimming pool, a dude ranch corral, plenty of acreage for horseback riding, a big old guest house for the lodgers, and a connecting building that was the bar and restaurant. In the barroom the floors, the tables, the chairs, the walls, the beams, the bar were of the sort known as extremely weatherbeaten, and the screen doors kept banging. Nobody putting together such a place for a movie about flying in the old days would ever dare make it as dilapidated and generally go-to-hell as it actually was. Behind the bar were many pictures of airplanes and pilots, lavishly autographed and inscribed, badly framed and crookedly hung. There was an old piano that had been dried out and cracked to the point of hopeless desiccation. On a good night a huddle of drunken aviators could be heard trying to bang, slosh, and navigate their way through old Cole Porter tunes. On average nights the tunes were not that good to start with. When the screen door banged and a man walked through the door into the saloon, every eye in the place checked him out. If he wasn't known as somebody who had something to do with flying at Muroc, he would be eyed like some lame goddamned mouseshit sheepherder from Shane.

The plane the Air Force wanted to break the sound barrier with was called the X-1 at the outset and later on simply the X-1. The Bell Aircraft Corporation had built it under an Army contract. The core of the ship was a rocket of the type first developed by a young Navy inventor, Robert Truax, during the war. The fuselage was shaped like a 50-caliber bullet—an object that was known to go supersonic smoothly. Military pilots seldom drew major test assignments; they went to highly paid civilians working for the aircraft corporations. The prime pilot for the X-1 was a man whom Bell regarded as the best of the breed. This man looked like a movie star. He looked like a pilot from out of Hell's Angels. And on top of everything else there was his name: Slick Goodlin.

The idea in testing the X-1 was to nurse it carefully into the transonic zone, up to seven-tenths, eight-tenths, nine-tenths the speed of sound (.7 Mach,.8 Mach,.9 Mach) before attempting the speed of sound itself, Mach 1, even though Bell and the Army already knew the X-1 had the rocket power to go to Mach 1 and beyond, if there was any beyond. The consensus of aviators and engineers, after Geoffrey de Havilland's death, was that the speed of sound was an absolute, like the firmness of the earth. The sound barrier was a farm you could buy in the sky. So Slick Goodlin began to probe the transonic zone in the X-1, going up to.8 Mach. Every time he came down he'd have a riveting tale to tell. The buffeting, it was so fierce—and the listeners, their imaginations aflame, could practically see poor Geoffrey de Havilland disintegrating in midair. And the goddamned aerodynamics—and the listeners got a picture of a man in ballroom pumps skidding across a sheet of ice, pursued by bears. A controversy arose over just how much bonus Slick Goodlin should receive for assaulting the dread Mach 1 itself. Bonuses for contract test pilots were not unusual; but the figure of $150,000 was now bruited about. The Army balked, and Yeager got the job. He took it for $283 a month, or $3,396 a year; which is to say, his regular Army captain's pay.
