Grand Prairie, Texas: Two Mustangs
Wild Spanish horses ran this prairie for three centuries — then a plant on the same grass built 4,790 fighter planes named after them.
Three stories posted across one week in July 2026 — the Spanish horses that went wild on this grass, the windowless plant that built the fighter carrying their name, and the Navy that trained pilots hundreds of miles from any ocean. Each part below is the full post as published, with the reel or carousel it accompanied.

› The quarter horse traces its foundation stock in part to those same Spanish mustangs
› Hensley Field: the city of Dallas bought the land and leased it to the Army in 1928
› The fighter was named by the British; the Americans tried “Apache” first, and dropped it
› Avion Village: 300 federal homes built just to house the plant's arriving workers
› Through the wartime base: WAVES, Free French forces — and three future astronauts

Before it was a plane or a car, it was a horse. And before it was a horse here, it was a horse in Spain.
The first Spanish horses on record reached Texas in 1542 with the Moscoso expedition — and the ones that got loose became the mustangs of the prairies.
The first Spanish horses on record reached Texas in 1542, carried in on the Moscoso expedition. Over the next two centuries some escaped, some were traded, some were simply turned loose, and the ones that survived went wild on the grass. They fanned out across the plains and became something the Spanish had a word for — mesteño, roughly “belonging to the stockmen,” a horse with no owner but the range. English chewed it down to mustang.
By the 1800s they were the great curiosity of the Texas prairies. Travelers wrote about standing still and watching bands of them pour across open country in numbers nobody could count. They were smaller than the horses settlers brought from the east, and tougher — they could work all day on bad water and thin grass, which is exactly why every cattle range in Texas ended up running them.
The grasslands between the Trinity forks were part of that country. Open prairie, deep grass, few trees, and horses on it long before anyone drew a county line across it.
They didn't last. Fences went up, the open range closed, and the wild bands were caught, broken, or driven off. But they didn't vanish, exactly — they got absorbed. The quarter horse, the breed Texas still runs and still argues about, traces its foundation stock in part to those same Spanish mustangs.
So the horse is still out there. It just answers to a different name now.

Part II — Wed Jul 29, 2026 · Two Mustangs, One Grassland
Wild horses ran these prairies. Ninety years later, the prairie was building fighter planes named after them.
In September 1940 a town of 1,595 people broke ground on a windowless plant that would build 18,000 airplanes — 4,790 of them Mustangs.
The horses were here first. The land Grand Prairie sits on was Peters Colony prairie — open grass between the Trinity forks, crossed by trading paths long before anyone platted a town. The settlers who came in the 1840s didn't have to invent names for what they found. They called one spring-fed branch Mustang Branch because Spanish horses ranged along it, and the horses were plentiful. There's still a Mustang Creek running northeast into Tarrant County. The names outlasted the herds.
The railroad took the founder's name off the map. A settler named Dechman started the place in 1863. When the Texas & Pacific reached the depot in 1876, the line renamed the place for the grassland it sat on — Grand Prairie, 1877. It incorporated in 1909 as a farming and ranching crossroads, and stayed one for thirty years.
Then, in September 1940, ground broke on an aircraft plant beside Hensley Field. Grand Prairie was a town of 1,595 people. The plant was concrete and steel with no windows at all — the first fully air-conditioned, artificially lit aircraft factory in the country, a sealed box on a prairie where you can watch weather coming from miles off. The federal government built 300 homes at Avion Village just to house the people arriving to work in it.
From August 1941 to August 1945 that plant turned out 12,967 Texan trainers, 966 Liberator bombers, and 4,790 Mustangs.
And the plane got its name secondhand. The British ordered it first and christened it Mustang. The Americans wanted to call the Mustang fighter plane the Apache, tried it, and dropped it in favor of the British name. Everyone agrees the British took it from the wild horses of the American West. Nobody wrote down why.
Lone Star Park opened in 1996. The horses came back to the prairie.

Part III — Sat Aug 1, 2026 · The Prairie Navy
4,790 Mustangs came off that line. It still wasn't the plane the prairie made most of.
The plant's real output was the trainer — 12,967 T-6 Texans — built beside a Navy base that taught pilots to fly hundreds of miles from any ocean.
Before it armed anyone, it taught them to fly. The fighter gets the posters. But the aircraft that came off that Grand Prairie line in the greatest number by far was the T-6 Texan — 12,967 of them, nearly three times the Mustang count. The Texan wasn't built to fight. It was built to teach. Almost every American pilot of the war learned the feel of a fast, unforgiving trainer aircraft in one, and a lot of them learned it badly before they learned it well.
Next door sat the field the trainers were made for. Hensley Field had been an Army airfield since the city of Dallas leased the land in 1928. In May 1941 the Navy commissioned a reserve aviation base on part of it, and somebody looked at the map, saw how many hundreds of miles of dry country stood between that runway and the nearest ocean, and started calling it the Prairie Navy. The name stuck.
What came through it is the strange part. Fleet pilots and Marines. Coast Guard. WAVES — the women in the Navy who enlisted for emergency service and kept the place running. A contingent of Free French forces, a long way from France. And three men who would later leave the atmosphere entirely.
By the end of the war the field held 4,104 people. It's the Grand Prairie Armed Forces Reserve Complex now, and the runway is still there.
Wild horses, then fighter planes, then astronauts. Same grass.
