Doc, the B-29 Superfortress That Spent Decades as a Firefighter's Target in the California Desert and the Sixteen-Year Restoration That Brought Her Home to Wichita

Doc is one of two airworthy Boeing B-29 Superfortresses remaining in the world. She spent roughly three decades as a firefighter training prop at China Lake Naval Air Weapons Station in California, scorched repeatedly and left to bake in the desert sun. A sixteen-year restoration by hundreds of volunteers in Wichita, Kansas - the city that originally built more B-29s than anywhere else - returned her to flight on July 17, 2016, after sixty years on the ground.

What Made the B-29 the Most Advanced Aircraft of Its Era?

Boeing began designing the Superfortress in the late 1930s around a requirement that was simple to state and nearly impossible to meet: carry ten tons of bombs three thousand miles and bring the crew home. The airplane that emerged was revolutionary on nearly every front.

The B-29 featured a pressurized fuselage - a capability that sounds routine today but was engineering at the absolute edge of what was possible in the early 1940s. Crews could fly at altitude without oxygen masks or heated flying suits. No heavy bomber had offered that before.

It also carried remote-controlled gun turrets operated electronically from sighting stations throughout the aircraft. A central fire control computer could coordinate multiple turrets tracking a single target simultaneously. In 1943, that was state-of-the-art combat technology.

Then there were the engines. Each B-29 carried four Wright R-3350 Duplex Cyclone radials - 18 cylinders, 2,200 horsepower each. They were big, powerful, and famously temperamental. The nacelle design created chronic cooling problems, and engine fires claimed more than a few crews before they ever reached Japanese airspace.

The B-29 development program cost rivaled that of the Manhattan Project - the price of building the Superfortress was in the same range as building the atomic bomb itself. The war didn’t wait for perfect engineering, so it went into service anyway.

How the B-29 Changed the Air War Against Japan

The Superfortress entered combat in 1944, flying from bases in India and China in an operation called Matterhorn. The logistics were punishing. Fuel, parts, and supplies all had to be flown over the Himalayas - the Hump - from India into China. It took roughly seven gallons of fuel to deliver one gallon to a forward base. The math never worked, and the campaign was eventually abandoned.

General Curtis LeMay relocated the B-29 campaign to the Mariana Islands - Tinian, Guam, and Saipan - where the distances to Japan finally made operational sense. Then he changed the tactics entirely.

LeMay stripped the guns from most of his aircraft, removed the armor, loaded them with incendiary bombs, and sent them in at low altitude, at night. Conventional doctrine said that was suicidal. But Japanese night fighter and anti-aircraft defenses were calibrated for high-altitude attack. They weren’t ready for what came next.

On the night of March 9–10, 1945, more than 300 B-29s flew over Tokyo and dropped incendiary bombs. Sixteen square miles of the city burned. By most measures, it remains the deadliest air raid in history - including Hiroshima.

Five months later, Enola Gay and Bockscar carried atomic bombs to Hiroshima and Nagasaki. The war ended. The Superfortress had done what it was built to do.

How Doc Ended Up as a Firefighter’s Training Target

After the war, surviving B-29s were flown to storage or scrapped. A group of them at China Lake Naval Air Weapons Station in California were transferred to the base for firefighter training and crash rescue drills. Having a real heavy bomber to drag hoses around and practice suppression techniques on was genuinely useful.

The airplanes were named after Snow White’s seven dwarfs - Doc, Sleepy, Bashful, Happy, and others. By then they were training props, not aircraft. Every few months, crews would spray them with fuel, ignite them, practice suppression, extinguish the fire, and leave the airframes to bake in the desert until the next exercise.

That went on for decades.

The Discovery That Started Everything

In 1987, a businessman named Tony Mazzolini visited China Lake on unrelated business. Walking past the ramp, he saw Doc sitting there - weathered, scorched in places, but structurally intact. The bones of the airplane were still there.

Mazzolini had ties to Wichita, Kansas. And Wichita had built more B-29s than anywhere else on earth. Boeing’s Wichita plant was one of the primary production facilities for the Superfortress during the war, and thousands of people in that city - and their parents - had assembled those aircraft on the line.

He started asking questions. Who owned the airplane? Could it be moved? What would it take to get it released? The Navy was not enthusiastic. It took the better part of a decade of phone calls, letters, and bureaucratic patience. In 1998, the Navy transferred Doc to a non-profit called Doc’s Friends.

The Sixteen-Year Restoration in the City That Built Her

Doc was moved to a hangar at what is now Eisenhower National Airport in Wichita - the same city where she was originally manufactured. That detail mattered deeply to everyone who showed up to work on her.

And people showed up. Hundreds of volunteers - some who had never held a rivet gun, some retired aerospace workers who immediately understood the scope of the task, and some who simply arrived on a Saturday morning because they wanted to be part of something that mattered.

The restoration took sixteen years and 300,000 volunteer hours. Worked at eight hours a day, seven days a week with no days off, that represents more than a hundred years of a single person’s labor.

Parts for a type not manufactured in decades don’t come easily. Some came from museums, some from private collections, and some had to be machined new from original drawings because no other source existed. The four Wright R-3350 engines each had to be located and fully overhauled. The population of mechanics with experience rebuilding one of these engines for actual flight is not large. The team found that expertise wherever it still existed and worked out solutions that even the original engineers hadn’t anticipated.

Every system on the aircraft - wiring, plumbing, instrumentation, hydraulics, pressurization - was disassembled, inspected, repaired or replaced, and reassembled correctly. Through all of it ran a single question: is this thing going to fly, or are we building a very expensive static display?

Doc’s First Flight in Sixty Years

On July 17, 2016, Doc lifted off from Wichita.

1956 was the last time those wheels had left the ground. Sixty years on a training ramp and in desert storage, and then she flew again. Volunteers who had worked the restoration for over a decade stood on the ramp and watched her go.

Some of the women and men who had built B-29s in Wichita during the war were still alive in 2016. A few came out to watch. They had built something enormous in their twenties - something the world depended on - and eight decades later, they watched it fly again. That is not nostalgia. That is a bridge across time that very few things in life can build.

Why Seeing Doc Fly Is Worth the Trip

Of the nearly 4,000 B-29s built during the war, two airworthy examples survive. Doc is one. FIFI, operated by the Commemorative Air Force, is the other.

A B-29 in a museum tells you it existed. A B-29 at an airshow - four big radials turning, prop wash pushing spectators back, the sound of 8,800 horsepower registering in your chest - gets you meaningfully closer to what it actually felt like.

The crews who flew B-29s in combat were mostly 21 to 23 years old. Twelve men in a pressurized tube at altitude, fifteen to sixteen hours at a stretch, over a country where people were actively trying to kill them. Doc doesn’t hand all of that to you. But standing under a 141-foot wingspan and looking up, with those four engines cold and quiet before the airshow starts, gets you closer than any museum placard ever will.

Then they fire the engines, and you don’t have to imagine anymore.
