The Mustang That Wasn’t: Jimmy Stewart’s Record-Breaking P-51 and the $27 Scrap Heap That Fooled History

June 1955.

A P-51 Mustang plunges into a Nebraska wheat field, exploding into a 45-foot trench of fire.

The pilot has bailed out.

The engine is unrecognizable.

Six years earlier, that same aircraft had crossed America faster than any piston-engine racer in history — a record that still stands today.

Its owner then?

Jimmy Stewart.

So why did a Hollywood legend’s record-breaking Mustang die on a hail-suppression mission flown by a Texas pilot nobody remembers?

And what, exactly, is flying under that name today?

Here’s the strange part: the plane that ended up in that field was never supposed to exist.

It had no military serial number.

No combat record anyone could prove.

Its federal paperwork describes it not as a fighter but as a puzzle assembled from spare parts.

To understand how it ended up in a Nebraska ditch, we have to start somewhere far less glamorous than Hollywood.

We have to start with a scrap heap.

When World War II ended, America suddenly owned tens of thousands of combat aircraft it no longer needed.

In Kingman, Arizona, a contractor bought 5,483 surplus planes for $2,780.

Do the math.

That’s about 50 cents apiece.

Most were headed for smelters.

In Chicago, a small company called Allied Aircraft, run by Leland and Martha Cameron, was buying parts from that flood.

One of the things they bought was a P-51 Mustang fuselage.

The bill of sale classified it as scrap and damaged equipment.

The price: $27.05.

Where exactly did that fuselage come from?

Here the story goes murky.

The paperwork points to an Army depot near Chicago.

Decades later, Cameron told researchers it came from Kingman, and crash-site historians suspect it was a reconnaissance model, serial 44-10911.

Maybe.

No one has proven it.

What we know for certain is what the government wrote down.

The Civil Aeronautics Administration file contains one line you must remember, because it will return at the end of this story: “This aircraft was assembled from components of other aircraft of the same type.” Next to the service number box, someone wrote: “No service number.” The serial on the form, 2925, doesn’t match any Army or North American Mustang sequence.

It looks like a number clerks simply invented so the thing could exist on paper.

So this was a fighter built from the bones of other fighters, with a fabricated serial number, sold as scrap for $27.

Which raises the obvious question: in 1948, with surplus everywhere, why would anyone bother assembling a fighter from scrap?

The answer was a trophy and a straight line across the map.

The Bendix Race was a transcontinental dash.

Take off from California, fly flat-out to Cleveland, and the highest average speed wins.

No pylons, no laps — just speed, fuel, and navigation over 2,000 miles.

After the war, the race became a showcase for surplus military aircraft, and the Mustang was perfect for it.

In combat, the P-51 escorted bombers all the way to Germany and back.

It had to fly fast, for a long distance, for hours.

Strip away the war duties, and that is exactly the equation the Bendix rewards.

The long-range escort fighter is essentially a transcontinental racer carrying guns.

One man saw it first.

Paul Mantz was Hollywood’s best stunt and camera pilot, and Amelia Earhart’s former technical advisor.

He bought surplus P-51Cs, painted them red, sealed their wings into fuel tanks, and even chilled his gasoline with dry ice so it would contract and he could cram in more.

He won the Bendix in 1946.

He won it again in 1947.

He also set the transcontinental speed record.

If you wanted to win the Bendix, you had to beat Paul Mantz.

To do that, you needed three things: a Mustang, a pilot, and money.

In April 1948, the Camerons registered their assembled aircraft as N5528N.

Two days later, they sold it for $10 to a racing company called Joe De Bona.

That company had two partners.

The first was the pilot.

Joe De Bona was a former Army captain and experienced air racer.

According to the aircraft’s current owner, he spent the war as a transport pilot ferrying fighters and bombers across the oceans.

Transport pilots didn’t see combat.

They flew long distances in unfamiliar aircraft through bad weather, navigating precisely enough to arrive.

Hold that thought, because the Bendix is essentially a transport flight with a stopwatch.

The second partner was the money and the name: James Stewart.

By 1948, he already had an Oscar, but he was no movie star buying a toy.

He was a licensed pilot before the war, commanded B-24 bombers in combat over Europe, and came home a colonel.

Later, he would become a brigadier general in the Air Force Reserve.

He understood aircraft, and he understood what it took to fly one hard for hours.

So now you have the partnership everyone remembers.

And this is the version almost everyone imagines: Jimmy Stewart in the cockpit of a gleaming blue racer, chasing a record across America.

Keep that picture in your mind.

We’ll come back to it later — because the team first had to turn a $27 fuselage into the fastest Mustang in the country.

And they did it by taking things out.

The self-sealing fuel cells came out.

Those were rubber-lined tanks designed so that if a bullet punctured them, the rubber would swell and plug the hole before fuel leaked and caught fire.

The fuselage fuel tank came out.

The cannon ports were covered with smooth aluminum plates.

Every seam was filled with putty and sanded flat so air would slip over it instead of catching.

North American was testing an experimental high-speed propeller, and the team got one.

Then came the paint: 48 coats of primer and glossy cobalt blue, polished until it looked wet.

The team claimed the paint alone added about 8 mph.

Maybe, maybe not.

But think about what that claim tells you.

These people were chasing speed in the thickness of paint.

There’s a 1949 Life magazine photo of Stewart and De Bona beside the aircraft with a pile of everything they had stripped out of it.

That pile is the key to this whole story.

Everything in it had been put into a Mustang for a reason — not to slow it down, but to survive the day something goes wrong.

Remove those things, and the plane gets faster.

But it also becomes less prepared for that day.

They called it Thunderbird, race number 90, with a checkered tail, and under the cockpit on both sides they painted one more word: Experimental.

That word wasn’t decoration.

It was a leash.

There was no civilian type certificate for a P-51.

No one had ever proven a Mustang safe for civilian use.

So on August 31, 1948, Thunderbird received an experimental certificate with strict limits: races and exhibitions only.

No flying outside the continental United States.

No flying over crowds or populated areas.

Valid for one year.

The government allowed this aircraft to go fast.

It just didn’t want it doing much else.

That restriction will matter later.

Four days later, on September 4, 1948, Thunderbird lined up for its first Bendix Race at Van Nuys, California, with an early Packard-built Merlin engine making about 1,380 horsepower.

De Bona took off and headed east.

He didn’t finish.

Low on fuel, he landed in Norwalk, Ohio — 63 miles from the finish line.

After more than 2,000 miles, he ran out of race with about a daily commute to go.

Paul Mantz won again, his third straight.

That failure exposed the real problem.

The Bendix is not a speed race.

It’s a fuel race disguised as a speed race.

More speed means more fuel burn.

Carrying more fuel means more weight.

Every racer balances on a knife’s edge, and in 1948, Thunderbird fell off it 63 miles early.

So for 1949, they swapped in a newer Merlin, the engine most wartime Mustangs used.

And before the next Bendix, De Bona set out to break Mantz’s transcontinental record from Burbank to New York.

He tried once and failed.

He tried again and scrubbed the attempt.

Two tries, nothing.

On March 29, 1949, at a.m., he took off from Burbank for the third time.

He climbed to 30,000 feet in 17 minutes, where the winds could carry him.

Then he hit bad weather from the Colorado River to Missouri.

Over Akron, Ohio, the Merlin began losing oil.

The gauge should have read 70.

It dropped to 20.

In a liquid-cooled V12 running at full power, that is the difference between a working engine and a lump of metal.

He kept going.

Near Sunbury, Pennsylvania, his oxygen ran out.

At that altitude, without oxygen, your judgment doesn’t last long.

He descended to 19,000 feet and flew on.

Then, on approach into New York, the canopy cracked.

He crossed over LaGuardia at p.m.

Eastern.

He had left Burbank with 850 gallons of fuel.

He landed with about 30 gallons.

The papers said that was enough for roughly 7 minutes of flight. 5 hours and 5 seconds.

An official speed of 490.625 mph.

A new American record, beating Mantz’s old mark by over an hour.

De Bona didn’t look victorious.

Of the cockpit, he told reporters: “It scared me plenty.” Then he said he would never attempt another record flight.

Back in Los Angeles, Stewart gave De Bona full credit and insisted the aircraft hadn’t been modified — only painted, polished, and sanded. “That’s the first proof that the subtraction worked.”
But a record attempt is one aircraft against the clock.

The Bendix is a race.

Other aircraft, same day, chasing the same winds.

And Mantz’s team would be there.

On September 3, 1949, the Bendix launched from the dry lakebed at Rosamond — six aircraft, first time a simultaneous start.

Thunderbird against two crimson Mantz Mustangs, a Mosquito, an AT-12, and a B-26 flown by Leland Cameron himself.De Bona flew a precise line, riding tailwinds estimated at 30 mph.

He crossed Cleveland after 2,008 miles in 4 hours, 16 minutes, 17.5 seconds — 470.136 mph average.

Then came the wait.

Eleven minutes later, Stan Reaver arrived at 450.

A minute after that, Salmon at 449.

Same airframe, same engine, same sky.

Thunderbird had beaten them by 20 mph across a continent.

Paint, propeller, stripped weight, polished seams — a pile of small decisions adding up to 11 minutes.Stewart had married Gloria Hatrick McLean a month earlier.

One account says De Bona gave the newlyweds the trophy as a wedding gift.

A lovely detail — from later retellings, not documents.So let’s return to that picture.

Jimmy Stewart in the cockpit winning the Bendix.

You can understand why people believe it.

His name is in every headline.

Life magazine shows him beside the plane.

When it sold in late 1949, the paperwork listed him as sole owner of the racing company.

Jimmy Stewart’s P-51 is not a lie.

But in 1949, the press called Thunderbird De Bona’s Mustang, sponsored by Stewart and producer Robert Riskin.

Every documented race and record flight in this story was flown by Joe De Bona.

Stewart never raced it.

Whether he ever flew it at all remains debated.So the most famous fact about this aircraft — the one in the headline — is technically true and almost completely misleading.

The record belongs to the man who flew with 20 pounds of oil pressure, no oxygen, a cracked canopy, and a name almost no one remembers.Another uncomfortable detail: Thunderbird’s 470 mph remains the fastest piston-engine Bendix ever — partly because 1949 was the last year the race included a piston class at all.

Nobody broke the record because nobody was allowed to try.Two days after the win, a heavily modified Mustang crashed into a house at Cleveland, killing pilot Bill Odom and a young mother and her infant on the ground.

It’s widely cited as a key reason the great Cleveland air races ended.

Thunderbird’s best moment came at the last possible instant.What does a champion racer do when the races fade?

It sells.

Less than four months after the win, on December 19, 1949, Stewart sold Thunderbird to Jacqueline Cochran for one dollar and other considerations.

The paperwork never says what those were.

Cochran had won the Bendix herself in 1938, led the Women’s Airforce Service Pilots during the war, and finished third in the 1948 race where Thunderbird failed.On December 29, 1949 — the same day it was registered in her name — she flew it to two world records, averaging nearly 437 mph around a closed 500-kilometer course.

Not a straight line with a tailwind, but hard turns around a closed circuit.

In April 1951, another world record on a straight course at roughly 464 mph.

Then, in January 1953, she sold it back to Stewart.

Again for one dollar and other considerations.Stewart repainted it yellow and black and renamed it Mr.

Alex, after his father Alexander.

A new engine with water-and-alcohol injection could push the Merlin to roughly 2,280 horsepower.

And here the restrictions returned.On June 2, 1953, Queen Elizabeth II was crowned in London.

No live transatlantic television existed, so film had to be flown to Newfoundland and raced south.

CBS hired De Bona for the final leg in Stewart’s Mustang.

NBC hired Stan Reaver in one of Mantz’s Mustangs.

It was the 1949 Bendix all over again — except the prize was the evening news.But Thunderbird’s experimental certificate barred it from leaving the continental United States.

Picking up film from Canada was illegal for this aircraft.

So Stewart asked regulators to lift the restriction temporarily.

They agreed.

For a few days, the government loosened the leash.

De Bona took off from Goose Bay and landed in Boston 24 minutes ahead of Reaver.

He won again.

It didn’t matter.

A third network, ABC, broadcast the coronation images first.

The fastest plane won the race and lost the purpose.Remember De Bona’s vow to stop chasing records?

On March 31, 1954, he flew Thunderbird from Los Angeles to Idlewild in 4 hours, 24 minutes.

The National Aeronautic Association credited 560.74 mph.

Five years earlier, 490 had nearly killed him.And now a number that reframes everything: in March 1955, the airframe’s total flight time was just 150 hours.

The failed 1948 Bendix, the scrubbed attempts, the 490 record, the Bendix win, Cochran’s records, the coronation dash, the 1954 mark — all of it in about six days of flying.

The entire legend was written in less time than a long vacation.By then, the heroes were leaving the stage.

In September 1954, Stewart sold the plane to De Bona for one dollar plus a $7,500 mortgage.

In March 1955, the race engine was replaced with a postwar commercial Merlin.

The next day, De Bona sold Thunderbird to James M.

Cook of Jacksonville, Texas, for $18,000 plus a $7,000 mortgage.

For the first time, the plane belonged to no one famous.

It belonged to a man who intended to use it for work.

The work was weather.In the 1950s, farmers feared hail.

One storm could destroy a year’s crop in minutes.

An entire industry grew around the idea that if you flew into the right clouds and seeded them, you might weaken the storm before it did damage.

Cook worked for a outfit called Valley Hail Suppression, and if you needed an aircraft that could climb fast and reach big storm clouds, a Mustang was a logical choice.On June 22, 1955, around 6 p.m., Cook took off from Scottsbluff, Nebraska.

Then the landing gear malfunctioned.

One main wheel refused to retract.

The other refused to extend.

Imagine it: one leg hanging, one folded inward.

You can’t land normally with one wheel, and you can’t do a clean belly landing because that hanging wheel could dig in and flip the plane.

Cook wrestled with the problem for about an hour and a half.Now remember that pile of parts.

Remember the wings sealed tight to carry fuel.

A Mustang carrying fuel in its wings, hitting the ground on one wheel, means a fuel tank tearing open at high speed.

Restorers who later worked on this aircraft note that landing a Mustang with stuck gear was exactly the risk no pilot wants to take.

The modifications that made Thunderbird fast made this moment more dangerous.Why did the gear fail?

No one can say for certain.

B and C model Mustangs used an older, lighter landing gear door with a single latch.

During the war, some of those doors tore away in high-speed dives, and North American redesigned the system for the later D model.

Restorers believe the old doors may have been rigged in the wrong sequence, jamming the gear.

Maybe.

A plausible theory, unproven.Cook made his decision.

He climbed out and jumped.

At that evening, Thunderbird hit the ground north of the small town of Morrill, Nebraska.

It exploded and burned.

A reporter described a trench six feet deep and 45 feet long, with pieces scattered up to 100 yards.

The engine was unrecognizable.

Cook survived.

He bought another Mustang and spent years flying for the U.S.

Weather Bureau, studying thunderstorms.And here’s the last strange detail.

The accident report was completed that July.

Today, neither the FAA nor the NTSB has it in their files.

In August 1955, N5528N was struck from the civil register.That is what happened to Jimmy Stewart’s record-breaking P-51.

Sold for a dollar, sold again, sold to a stranger, put to work over farmland, and destroyed in a field.

Six years after crossing America faster than any piston racer ever had.But if the story ended there, you wouldn’t see this aircraft flying today.In Minot, North Dakota, a man had dreamed of Mustangs since childhood.

Warren Pietsch grew up in his father’s aviation company, and at age ten, he drew a P-51 on his bedroom wall and promised himself he’d own one someday.

He grew up to become a pilot of historic warbirds.On June 23, 1999 — 44 years and one day after the crash — Pietsch bought the tailwheel assembly and some other parts from a wrecked P-51 in Nebraska.

He thought he was buying pieces of an old, damaged P-51A.

Then he discovered what that aircraft had really been.

He contacted the FAA, explained the parts traced to serial 2925, and asked for ownership of that aircraft so he could rebuild it.

The FAA agreed.

In 2007, the aircraft was registered in his name under its original number.

N5528N existed again.Notice what came back first.

Not the airplane — the identity.

The serial number and the registration.

And remember where that serial number came from. 2925 was never a factory number.

It had been assigned to an aircraft already assembled from pieces of other aircraft.

Pietsch spent years gathering parts and doing slow structural work, then brought the project to Air Corps Aviation in Bemidji, Minnesota, to finish it.

There he made a decision that may upset purists.

He used the later D-model wing with stronger landing gear and redesigned doors — the same system North American built after the old doors caused problems.

North American had already tested fitting a D wing to a B or C fuselage during the war, making approval easier.

So the aircraft that most likely died from its landing gear came back with better landing gear.

That’s not a coincidence.

That’s a man learning the lesson of 1955.Then came the paint: 48 coats of primer again, the same glossy cobalt blue.

Race number 90, the checkered tail.

In June 2023, test pilot Bernie Vasquez flew Thunderbird for the first time since 1955.

Weeks later, it flew to Oshkosh, America’s biggest airshow, where crowds whispered the name you’d expect: “Jimmy Stewart’s Mustang.” It’s headed for the Dakota Territory Air Museum in North Dakota.But here’s the honest part, from the owner himself.

Pietsch says there’s a fair amount of original P-51 parts in the rebuild, but not much of the actual Thunderbird wreckage.

One historian who reviewed the full federal file put the word “restoration” in quotation marks.

So what flies under the name Thunderbird today?

Go back to that line in the 1948 paperwork: “This aircraft was assembled from components of other aircraft of the same type.” That sentence described Thunderbird when it was born from a $27 scrap fuselage, and it describes the aircraft flying today almost literally.That is the real answer to the headline.

Jimmy Stewart’s Mustang was never a fixed piece of metal.

It was scrap given a number, then a name, then a record.

The metal burned in a Nebraska field in 1955.

The number survived in a government file.

The name survived because of a movie star’s fame.

The record survived because no one was allowed to try to beat it again.The one thing that can’t be rebuilt is the flight itself.

A former transport pilot, no oxygen, oil pressure dropping, canopy cracking, landing with seven minutes of fuel.

That was Joe De Bona.

And if you’re going to attach a Mustang to someone’s name, it’s worth remembering who was actually sitting in the cockpit.So here’s my question for you: if the metal is gone but the number, the name, and the record live on — is the plane flying today the same aircraft, or just a very convincing ghost wearing its paperwork?

Tell me in the comments: where do you draw the line between restoration and resurrection?
