Thunder Over Michigan at Willow Run and the bomber plant runway where Rosie built Liberators

Thunder Over Michigan at Willow Run Airport (KYIP) in Ypsilanti, Michigan, is one of the premier warbird airshows in the country — not because of military jet demos, but because the vintage aircraft are the main event. They fly formation, they fly low, and they do it over the same 7,294-foot runway where B-24 Liberators first lifted off during World War II. The history is not a backdrop here. It is the point.

What Makes Willow Run Different From Other Airshows?

Most airshows treat warbirds as a nostalgic sideshow between modern military demonstrations. Thunder Over Michigan inverts that formula. The warbird content is the centerpiece, and the setting makes it irreplaceable.

In 1941, Henry Ford broke ground on the Willow Run Bomber Plant, which became the largest factory under one roof on the planet — 1.6 million square feet. At peak production, the plant rolled out one B-24 Liberator every 55 minutes. The workforce was predominantly women. Rosie the Riveter was not just a propaganda poster — she was a real worker on this assembly line.

The Yankee Air Museum, which organizes Thunder Over Michigan annually, occupies a section of the original bomber plant on the south side of the field. Walking through its doors means passing through the same entrance that thousands of wartime workers used six days a week.

What Aircraft Fly at Thunder Over Michigan?

The static display and flying demonstrations feature an impressive roster of authentic warbirds. On the ground, the lineup includes aircraft like the museum’s own B-25 Mitchell “Yankee Warrior” — wearing olive drab paint with original dents and patches that confirm a real operational history — and a Douglas C-47 Skytrain, the transport that dropped paratroopers over Normandy.

In the air, the flying program builds throughout the afternoon:

Four-ship T-6 Texan formation with 600-horsepower Pratt & Whitney radials in tight diamond passes
P-51 Mustang low passes showcasing the unmistakable howl of the Rolls-Royce Merlin engine
B-17 Flying Fortress flyovers with gear down and bomb bay doors open, powered by four Wright Cyclone engines producing 1,200 horsepower each
F4U Corsair and F6F Hellcat joint Pacific theater demonstrations
Stearman biplane aerobatics featuring knife-edge passes, hammerheads, and snap rolls

The Stearman performance is a consistent crowd favorite — proof that the most memorable act at a major airshow is not always the fastest or loudest, but the one flown with the most precision and character.

Can You Fly in a Warbird at the Show?

Yes. The Yankee Air Museum offers warbird rides during the event. A seat in the waist gunner position of the B-25 Mitchell runs approximately $150 for a 30-minute flight over the Michigan countryside. Expect long lines — the B-25 ride queue wraps around the hangar. These flights consistently rank as the most impactful experience at the show for attendees with family connections to World War II veterans.

What About the Yankee Air Museum?

The museum is worth dedicated time beyond the airshow itself. Its permanent collection includes a section on the Willow Run plant featuring original tooling, assembly line photographs, and period equipment including rivet guns used by the women who built bombers. A quote from Charles Lindbergh, who consulted at Willow Run during the war, is displayed on the wall, describing the extraordinary energy of thousands of people building something they believed would change the world.

Aviation artists set up in the vendor area with original works. One notable series of watercolors depicts every aircraft type built at Willow Run, with accurate detail distinguishing early-production from late-production B-24 nose sections.

How Do I Fly In to Thunder Over Michigan?

Thunder Over Michigan takes place every August at Willow Run Airport (KYIP) in Ypsilanti, Michigan. The field is a straight shot from anywhere in the Midwest. The FBO welcomes fly-in traffic, with grass parking available. The walk from aircraft shutdown to the first static warbird display takes roughly ten minutes.

The runway where general aviation pilots land today is the same runway where factory-fresh Liberators made their first flights. The ramp where visiting aircraft park is the same ramp where production workers reported for their shifts.
