Brooks Air Force Base Hangar 9

San Antonio, Bexar County, Texas

Marker Inscription

Built early in 1918 for JN-4 (Jenny) planes used in World War I pilot training. In later classes here were many great pilots, including Chas. A. Lindbergh, first man to solo across the Atlantic. "Old 9" was initiation site of Blind Flying instruction. Recorded Texas Historic Landmark - 1967

The Story

When the United States entered World War I, the Army rushed new airfields into service to train the pilots it suddenly needed. Hangar 9 rose at Brooks Field early in 1918 to shelter the fragile JN-4 "Jenny" biplanes that green aviators learned to fly. Among the airmen who passed through in the years that followed was Charles A. Lindbergh, later the first to fly solo across the Atlantic, and the hangar became a proving ground for early blind-flying instruction by instruments alone.

Why it matters

As one of the oldest surviving aircraft hangars in the country, it marks the birthplace of American military aviation training and the leap toward instrument flight.

The story behind this marker

AI context

The era

When the United States entered the First World War in 1917, it discovered it was almost completely unready for the newest weapon of the age: the airplane. Flight was barely more than a decade old, and the Army had only a handful of trained pilots. Almost overnight, the nation had to build airfields and teach thousands of young men to fly.

South Texas, with its flat land and long stretches of clear weather, became one of the great classrooms for that effort. New fields were laid out in a hurry, and hangars went up to shelter the fragile training planes that would carry raw recruits into the air.

Hangar 9 belongs to that scramble. Built early in 1918 at Brooks Field, it rose to house the biplanes on which a generation of American aviators would take their first, wobbling lessons — a piece of infrastructure thrown up fast to meet a need the country had never faced before.

People & events

The hangar was built for the JN-4 — the famous 'Jenny,' the humble two-seat biplane on which most American pilots of the era learned their craft. Slow, forgiving, and produced in great numbers, the Jenny was the airplane that turned civilians into flyers, and Hangar 9 was one of the places where that transformation happened.

Among the airmen who trained here in the years that followed was Charles A. Lindbergh, who would go on to become the first person to fly solo across the Atlantic. That a pilot of such later fame passed through these doors gives the ordinary-looking hangar an extraordinary connection to one of aviation's defining moments.

'Old 9,' as it came to be known, also served as an initiation site for blind-flying instruction — the discipline of flying by instruments alone, without reference to the horizon. Learning to trust the dials rather than the eyes was one of the hardest and most important leaps in early aviation, and this hangar was part of where that leap was taught.

Its place in the American story

As one of the oldest surviving aircraft hangars in the country, Hangar 9 stands at the very beginning of American military aviation training. It preserves the moment a nation with almost no air power set out, in a matter of months, to create one — and did so by teaching thousands of young men to fly.

The blind-flying instruction associated with the hangar points to an even larger turning point. As long as pilots could fly only in clear sight of the ground, aviation was hostage to the weather. Learning to fly by instruments freed aircraft from that limit and opened the way to modern all-weather flight.

And the thread running to Lindbergh ties this local structure to the wider American romance with flight — the leap from wood-and-fabric trainers over Texas to a lone crossing of an ocean, all within a single generation. Recorded as a Texas Historic Landmark in 1967, the hangar honors both the training and the technological daring of aviation's earliest days.

If you visit

Take in the sheer age of the structure. Standing before one of the country's oldest surviving hangars, you're looking at architecture built for airplanes when airplanes themselves were brand new — timber and open span designed to shelter craft made largely of wood and cloth.

Imagine the sound and motion of a training field in 1918: Jenny biplanes taxiing out, engines coughing to life, and nervous students climbing aboard for lessons that were genuinely dangerous. Then picture the harder work that also happened here — pilots learning to fly with their eyes on the instruments alone.

For anyone drawn to the story of flight, this is a stop with real weight. It fits well into a day exploring San Antonio's deep military-aviation history, and it rewards a quiet moment spent thinking about how far, and how fast, flying traveled from these doors.

Old S. J. Brooks Home

San Antonio, TX

Built about 1890 by builder T.R. Hertzberg to a design by architect M.T. Eckles, this late Victorian house was purchased in 1909 by Judge Sidney J. Brooks, first judge of the 57th District Court. His son, Sidney Brooks Jr., became one of the first U.S. cadets killed while training for World War I aviation duty in 1917. San Antonio's Brooks Air Force Base was named in the young flier's honor.

Edward H. White II Memorial Hangar, Brooks Air Force Base

San Antonio, TX

San Antonio was a cradle of American military aviation, and this hangar at Brooks Air Force Base honors astronaut Lt. Col. Edward H. White II, the first American to walk in space, tethered to his Gemini craft in June 1965. White died in the January 1967 Apollo launch-pad fire while training for the first Moon flight; his own father had learned to fly at nearby Hangar 9, as did Charles Lindbergh. That standard WWI-era hangar once sheltered Curtiss JN-4 "Jenny" trainers, linking the pioneers of powered flight to the astronauts who followed.

Stinson Airport

San Antonio, TX

Founded by the remarkable Stinson family, this field has seen aviation grow from barnstormers to jets. Katherine Stinson learned to fly in 1912 to fund her music studies and became the fourth licensed woman pilot in the U.S.; she and sister Marjorie soon trained American and Canadian military fliers here. The family leased this land in 1916, and the field served as a civil airport, a WPA-improved terminal, and an Army Air Corps training base through two world wars — Charles Lindbergh himself flew out of it.

Barbed Wire

San Antonio, TX

Cowboys called it "Devil's Rope," and Texas cattlemen wanted nothing to do with barbed wire until a showman named John Ware Gates staged a dramatic proof on San Antonio's Military Plaza in the late 1870s. He penned frenzied longhorns behind a barbed-wire corral, prodded them with torches, and watched the flimsy-looking fence hold as skeptics lost their bets. Orders soon outran supply, and Gates went on to build wire and steel plants and to invest in the Spindletop oil boom.
