Flak-Bait, the Martin B-Twenty-Six Marauder, and the Smithsonian Conservation That Kept the Most Battle-Tested Airframe in American History from Disappearing

Flak-Bait, a Martin B-26 Marauder with serial number 41-31773, flew 207 combat missions over occupied Europe during World War II - more than any B-17, any B-24, or any fighter that flew under American colors in the entire conflict. She is the most combat-experienced American aircraft to survive the war, and for decades after it ended, she sat in a government storage building while almost no one knew she was there. What the Smithsonian eventually chose to do with her - and why - is a story about what historical preservation actually means.

Why the B-26 Marauder Had a Reputation for Killing Its Own Crews

The Glenn L. Martin Company designed the B-26 in response to a 1939 Army Air Corps requirement for a medium bomber, chasing speed and range above everything else. The engineers gave it a deliberately short wing. High wing loading produced a fast, clean aircraft - and an approach speed that left almost no margin for error. Flying the pattern at 150 mph over the fence was not unusual.

The aircraft did not tolerate imprecision. Crews transitioning from more forgiving trainers ran into trouble fast. Training accident rates climbed at bases in Florida until the gallows-humor phrase one a day in Tampa Bay was making the rounds through the barracks. The death toll was serious enough that Congress opened a formal investigation and the Army considered canceling the program.

How Jimmy Doolittle Changed the B-26’s Trajectory

General Jimmy Doolittle intervened. He went to one of the training bases and flew the B-26 in front of the crews - approaches at minimum speed, single-engine work with one propeller feathered - and demonstrated that the aircraft would perform safely and predictably within its parameters. The problem was not the airplane. The problem was that the airplane demanded precision and the training pipeline wasn’t yet producing it.

Revised training programs brought crews up to the aircraft’s standards. The outcome in combat was striking. By the final year of the war, the B-26 had the lowest loss rate over enemy territory of any American bomber in the European Theater. The same high wing loading that had made it dangerous in training made it fast enough to challenge German interceptors. The Widow Maker had become one of the most survivable platforms in the theater.

Flak-Bait’s Combat Record: 207 Missions, More Than 1,000 Holes

Flak-Bait was assigned to the 449th Bomb Squadron, 322nd Bomb Group, Ninth Air Force, flying first from England and later from bases on the continent as Allied armies pushed east through the fall of 1944 into the spring of 1945. Her crew named her with the flat, dry humor of people trying to make the unthinkable sayable.

Flak was the defining terror of medium bomber operations. On a bomb run, crews flew straight and level regardless of the black puffs appearing around the formation, because the bombardier needed a stable platform. You could not maneuver against flak effectively. You could not shoot back at it. You held your course and you waited.

Over two years of operations, ground crews patched more than 1,000 documented holes in her airframe - fragments through the skin, damage to engines, hits that missed fuel lines and spars by margins crews preferred not to examine too closely. Each time, the ground crews closed up the holes and put her back in the air.

Her 207th and final mission was flown on May 9, 1945 - one day after Victory in Europe Day. Then she sat.

How the Smithsonian Acquired Flak-Bait - and Almost Lost Her to Decay

When Germany surrendered, the Army faced thousands of surplus aircraft and blunt logistics. Most were cut up for aluminum. The Marauders that had survived the air war vanished by the hundreds and then by the thousands. Martin built more than 5,000 B-26s. Nearly every one was scrapped.

Someone at the Smithsonian Institution recognized that Flak-Bait was a documented record holder with a verifiable mission-by-mission history traceable through the 322nd Bomb Group’s records. The Smithsonian acquired her not long after the war and moved her into storage.

Storage, however, is not a neutral state. An aircraft sitting in a warehouse is slowly degrading - humidity, temperature cycling, oxidation of aluminum, deterioration of original paint and fabric. The B-26 was built for a service life measured in months of hard combat use, not decades on a storage floor. By the time Smithsonian conservation teams assessed the complete airframe seriously, they found an aircraft in genuine trouble.

Why the Smithsonian Chose Conservation Over Restoration

The museum faced a choice that isn’t simple. A flying restoration would mean replacing deteriorated components, rebuilding where necessary, and returning the aircraft to airworthy condition. The warbird community does exactly this, and does it with extraordinary skill. Watching a Marauder fly at an airshow is an experience that a static display cannot replicate.

But Flak-Bait was not a type example. She was not meant to represent what a B-26 looked like rolling off the Martin production line in Baltimore. She was this specific aircraft with this specific history. The thousand-plus repaired battle damage holes were not imperfections. They were the documentary record of what this airplane had survived - each one a specific moment over occupied Europe, written into the aluminum itself.

The Smithsonian chose conservation. Conservation preserves what is actually there. Restoration replaces what was there with something new.

The Conservation Work at the Udvar-Hazy Center

The conservation work on Flak-Bait’s fuselage and wing sections was carried out at the Steven F. Udvar-Hazy Center in Chantilly, Virginia, the Smithsonian’s large facility near Dulles Airport. Staff conservators, historians, and skilled volunteers worked through the aircraft piece by piece - assessing every inch of original material, documenting it, determining what was structurally stable and what was failing, and stabilizing deteriorated surfaces using techniques designed not to cause their own damage over the next half-century.

In the process, they found things the historical record hadn’t fully captured. Repairs that could be cross-referenced against specific mission dates in the group’s records. Evidence of damage events visible in the patches and the paint over them, readable in the metal itself.

The finished aircraft does not look like a freshly painted warbird at an airshow. The original finish is worn and dull in places. The repairs over battle damage are visible. The mission tallies on the nose count their way through two years of war, tally mark by tally mark, and the years show in the surface itself.

She looks like an airplane that actually flew 207 combat missions. Because she is.

Where to See Flak-Bait Today

The nose section - with original nose art and mission tallies - is on display at the National Air and Space Museum on the National Mall in Washington, D.C., in the company of the Wright Flyer, Lindbergh’s Spirit of St. Louis, and the Apollo 11 command module.

The complete airframe is at the Udvar-Hazy Center in Chantilly, Virginia. The Udvar-Hazy Center holds more significant aviation history per square foot than anywhere else in the country, and Flak-Bait alone is reason enough to make the drive.

As a type, the B-26 Marauder is one of the most completely vanished aircraft of the Second World War. Of more than 5,000 built, only a handful survive anywhere in the world, and most are incomplete. Flak-Bait is the most complete surviving example - and the only one preserved specifically as a combat artifact rather than a restored type representative.

Key Takeaways

• Flak-Bait flew 207 combat missions - more than any other American aircraft in World War II, including all B-17s, B-24s, and fighters.
• The B-26 Marauder’s early reputation as a “Widow Maker” stemmed from demanding handling qualities that high wing loading produced, not a fundamental design flaw; General Jimmy Doolittle helped correct the training approach.
• Ground crews documented and patched more than 1,000 battle damage holes in Flak-Bait’s airframe over two years of combat operations.
• The Smithsonian chose conservation over restoration, preserving the original damaged and repaired surfaces as historical evidence rather than returning the aircraft to factory appearance.
• The nose section is at the National Air and Space Museum in Washington, D.C.; the full aircraft is at the Udvar-Hazy Center in Chantilly, Virginia.
