Doc, the B-29 Superfortress Abandoned on a California Bombing Range, and the Wichita Volunteers Who Spent Eighteen Years Bringing Her Back to Life

Doc, a Boeing B-29 Superfortress built in Wichita in 1945, spent roughly four decades as a bombing target at the Naval Air Weapons Station at China Lake, California before a retired Boeing engineer spotted her in 1987 and refused to leave her there. What followed was an eighteen-year volunteer restoration effort - approximately 300,000 hours of donated labor - that returned her to flight on July 17, 2016, making her only the second airworthy B-29 in existence.

What Made the B-29 Superfortress the Most Complex Aircraft of World War II

In 1942, the B-29 was the most technologically complex aircraft ever put into mass production. It flew above 30,000 feet with a pressurized fuselage - still experimental technology at the time - cruising above most weather and above the operational ceiling of most enemy interceptors.

Her four Wright R-3350 Duplex-Cyclone radial engines each produced over 2,000 horsepower. The aircraft weighed 60,000 pounds empty and could carry 20,000 pounds of bombs. She also featured a remote fire control system allowing gunners to operate turrets from inside pressurized fuselage sections via periscopic sights - practical wartime engineering that would have seemed implausible a decade earlier.

The R-3350s had a well-earned reputation for running hot and catching fire at altitude. The engineers knew it. The crews knew it. They flew her anyway, because she could do things no other bomber in the world could do.

How the B-29 Ended the War in the Pacific

The Enola Gay and Bockscar - both B-29s - dropped the atomic bombs on Japan. The firebombing raids over Tokyo in March 1945, which reduced much of the city to ash in a single night, were B-29 missions. When Japan surrendered that August, the type had not only shortened the war, it had reshaped the entire logic of what an aircraft could accomplish.

Pressurized airliners, high-altitude jets, remote weapons systems - all trace a lineage back to problems the B-29 forced engineers to solve.

Wichita Built More Than 1,500 B-29s

The Boeing plant in Wichita ran around the clock through the war years. Tens of thousands of workers - many of them women who had never entered a factory before December 1941 - built more than 1,500 of the nearly 4,000 B-29s that rolled off American assembly lines. The workers on that floor knew every rivet, every weld seam, every part number. They were building the weapon that would end the war in the Pacific, though most could not yet imagine exactly how.

Doc came off that Wichita line in 1945. She served with the Army Air Forces and then the newly independent United States Air Force through the postwar years, including the Korean War, where B-29s flew missions until jet-powered fighters made high-altitude daylight bombing untenable. They switched to night operations and kept going. By the mid-1950s, the jet age had arrived in force and the B-29 was retired from front-line service. Doc ended up at China Lake as a static target.

How a Boeing Retiree Found Doc on a Bombing Range

In 1987, a Boeing retiree named Tony Mazzolini was at China Lake on an unrelated project. Among the decommissioned hulks in the desert, he found a B-29. Battered, sun-bleached, full of holes from decades of weapons testing - but structurally intact. Forty years of Mojave heat had desiccated rather than rotted what remained. Aluminum doesn’t rust.

Mazzolini knew exactly what he was looking at. He knew the only flying B-29 was the Commemorative Air Force’s FIFI, and that every other surviving example sat behind a museum rope. He made the kind of decision that costs you the next decade of your life: he was going to get this airplane out of there.

Securing an aircraft’s release from military custody is neither fast nor simple. It took years of negotiation with the Navy, years of paperwork, years of Mazzolini and the growing community he assembled simply refusing to give up. They called themselves Doc’s Friends. Their case: the airplane was historically significant, it could fly again, it could represent the thousands of workers who built her and the crews who flew her in combat.

The Navy agreed. In 1998, Doc was loaded onto a flatbed and hauled back to Wichita - back to the city, and the Boeing facilities, that had built her.

Eighteen Years and 300,000 Volunteer Hours

The restoration took eighteen years and was done entirely by volunteers. Hundreds of them, over those years: mechanics, engineers, machinists, sheet metal workers, electricians. People who gave weekends, vacation days, and entire retirements to the project. The total volunteer hours came to approximately 300,000. If a single person worked 40 hours a week, 50 weeks a year with no breaks, it would take 150 years.

Word spread around Wichita that someone was restoring a B-29 at the airport. That word reached people in their seventies, eighties, and nineties - people who had worked the original assembly line during the war. Women who had been teenagers when they first walked into the Boeing plant and learned to run a rivet gun. They didn’t come as visitors. They put on work gloves and went to work.

Some recognized specific construction details in the airframe - the exact rivet patterns, the way particular seams were run, what a specific fitting was supposed to look like. Living institutional memory, carried for six decades in the hands of people who were running out of time to pass it on. There is no budget line for that. There is no way to calculate what it was worth.

The Technical Challenges of Restoring a B-29

The B-29 is a maintenance challenge under ideal conditions. The R-3350 radials were notorious during the war for running hot - inadequate cowl flaps, marginal cooling, a tendency to throw oil and catch fire at altitude. Ground crews and flight crews developed workarounds, and that hard-won knowledge now exists only in documents and the memories of people who are leaving us every year.

The electrical system is a subject unto itself. The pressurization system requires specialized understanding that exists in no current training curriculum. The fire control system is a marvel of 1940s engineering that makes no intuitive sense without someone who knows it walking you through it.

Doc’s volunteers worked through every system one at a time. They sourced parts from museums, other B-29s, and the warbird parts network. They fabricated what couldn’t be found. They solved problems with no existing reference because Doc’s specific situation was unique.

Doc’s First Flight: July 17, 2016

Tony Mazzolini did not live to see it. He passed before the work was done, and that is a hard thing to know. His organization and his volunteers carried the project across the finish line.

On July 17, 2016, at Colonel James Jabara Airport in Wichita - named for World War II and Korean War ace Colonel James Jabara, a Wichita native - Doc’s four R-3350 radials started one by one. She taxied to the runway. She lifted off on the first attempt, climbed out clean over the Kansas plains, and flew for approximately two hours while the crew ran through systems and tested procedures.

In the crowd were people who were very old and very quiet. People who had shown up with their own tools on Saturday mornings for years. People who had worked the Wichita production line during the war and had not expected to live to see this.

When Doc touched down and the engines spooled down, the crowd let out a breath it had been holding for a very long time.

Why Doc Still Matters

Doc now tours the air show circuit out of Wichita. She occasionally appears alongside FIFI, which means it is possible - at the right air show, in the right year - to watch two flying B-29s in the air at the same time. Two, out of nearly 4,000 built.

The people who worked on these airplanes or flew them in combat are a small and rapidly shrinking number. The systems knowledge, the construction memory, the institutional understanding of how a B-29 actually works - these things exist in documents, in a handful of surviving volunteers, and in the restored aircraft themselves. Doc flying is not just a warbird attraction. It is a preservation of knowledge that cannot be re-created once it is gone.
