The Lake Michigan warbird graveyard and the freshwater fighters pulled from the bottom and restored to fly again

Between 1942 and 1945, the U.S. Navy trained over 17,000 carrier pilots on Lake Michigan using two converted Great Lakes excursion steamers. During those training operations, an estimated 130 to 140 aircraft — Hellcats, Wildcats, Corsairs, Dauntlesses, and Avengers — sank to the lake floor after failed carrier landings. Preserved by cold, salt-free freshwater, many of these warbirds have been recovered in remarkable condition and some have been restored to flying status.

Why Did the Navy Train Carrier Pilots on Lake Michigan?

After Pearl Harbor, the Navy faced an urgent problem. It needed thousands of carrier-qualified pilots, but every fleet carrier was deployed in the Pacific. Pulling a ship like the Lexington or Yorktown back for training wasn’t an option.

The solution was unconventional. The Navy took two coal-fired paddlewheel excursion steamers — the Seeandbee and the Greater Buffalo, which had operated tourist routes between Cleveland and Buffalo — and converted them into training carriers. Flat flight decks were welded on top of the passenger superstructures. They were commissioned as the USS Wolverine (IX-64) and the USS Sable (IX-81).

These ships operated on Lake Michigan within sight of the Chicago skyline, providing a controlled environment for carrier qualification far from enemy threats.

What Made Carrier Landings on These Ships So Difficult?

Carrier qualification is demanding under any circumstances. On a paddlewheel steamer making roughly 12 knots, with a flight deck barely 500 feet long, it was punishing.

Lake Michigan’s weather compounded the challenge. Conditions could shift from calm to four-foot swells in 20 minutes. Student pilots, many with only about 200 total flight hours, had to bring fighters like the FM-2 Wildcat aboard at approach speeds around 65 knots while a landing signal officer guided them in with paddles. The deck pitched unpredictably beneath them.

Most pilots made it. But enough didn’t. Aircraft bounced over barriers, caught gusts and went over the side, or came in at the wrong speed or altitude. The Navy kept crash boats standing by, and pilots almost always survived — the frigid water provided strong motivation to exit the cockpit quickly. The airplanes, however, went straight to the bottom. The Navy saw no reason to recover them. Replacements were rolling off assembly lines, and there was a war to fight.

How Did Cold Freshwater Preserve the Aircraft?

Lake Michigan provided near-ideal preservation conditions that no ocean environment could match. The key factors:

No saltwater corrosion. Salt is the primary destroyer of aluminum airframes in ocean wrecks. Lake Michigan’s freshwater eliminated this entirely.
No marine boring organisms. The wood and fabric components avoided the biological degradation common in saltwater environments.
Constant cold temperature. Bottom water stays at approximately 39°F (4°C) year-round, effectively creating a natural refrigerator.

Aircraft that entered the water relatively intact survived in conditions that astonished recovery teams decades later. Navy star insignia remained visible under thin coats of grime. Cockpit instruments sat in their original mounts. Some aircraft even contained personal effects — gloves, charts, pencils — left behind by pilots who scrambled to safety.

When Did Recovery Efforts Begin?

Serious recovery operations began in the late 1980s and early 1990s, driven largely by A. Taylor Vinson, a Chicago businessman and aviation history enthusiast. Vinson funded recovery efforts on behalf of the National Naval Aviation Museum in Pensacola, Florida, which aimed to build the world’s premier collection of naval aircraft.

The recovery process was painstaking. Divers worked in near-zero visibility, feeling through silt to locate wings, propeller blades, and fuselage outlines. Once an aircraft was identified and assessed, crews rigged lifting slings and attached cables to a barge crane on the surface. The crane then raised the aircraft slowly to avoid further damage.

The recoveries yielded an impressive range of types: SBD Dauntlesses (the dive bomber that turned the tide at Midway), TBM Avengers (the torpedo bomber flown by George H.W. Bush in the Pacific), FM-2 Wildcats, F6F Hellcats, F4U Corsairs, and SNJ Texan trainers.

Can These Aircraft Actually Fly Again?

Some of them have. Restoring a warbird that spent half a century underwater is an extraordinary undertaking, but several Lake Michigan recoveries have returned to the air.

One notable example: Bureau Number 92102, an SBD-2P Dauntless photo reconnaissance variant recovered in 1991 after nearly 50 years submerged. When it surfaced, the fabric control surfaces were gone, the engine was seized with corrosion, and the airframe was coated in lake-bottom grime.

The restoration required years of work. Every rivet hole was inspected. Every spar was X-rayed. The Wright R-1820 nine-cylinder radial engine was completely rebuilt using parts sourced from other wrecks, surplus dealers, and old Navy warehouses. The distinctive perforated dive brakes had to be fabricated from original engineering drawings.

When that Dauntless finally flew again in wartime Navy blue with a white star on the fuselage, its engine hadn’t run since a student pilot in a leather helmet tried to land on a converted steamship.

Where Can You See Lake Michigan Warbirds Today?

Recovered aircraft are displayed at museums across the country:

National Naval Aviation Museum in Pensacola, Florida — home to some of the finest examples from the recovery program
Air Zoo (Kalamazoo Air Zoo) in Kalamazoo, Michigan — features a restored Wildcat pulled from the lake
National WWII Museum in New Orleans — has benefited from Lake Michigan recoveries

The flying restorations appear at airshows around the country, where visitors can see and hear machines that last operated during World War II.

Are There Still Aircraft on the Lake Bottom?

Recovery efforts continue, though at a slower pace. The more accessible wrecks have been brought up. Remaining aircraft are deeper, more damaged, and more heavily silted over. However, side-scan sonar has mapped most of the known wreck sites, and improving underwater technology means additional recoveries remain possible. Some aircraft on the bottom have not yet been positively identified.

Meanwhile, Lake Michigan carries on above them. Commuters ride the Metra. Tourists visit Navy Pier. Sailboats cross the surface on summer afternoons. And roughly 200 feet below, a silent fleet of warbirds rests in the cold darkness where student naval aviators left them more than 80 years ago.
