The National Stearman Fly-In at Galesburg and the week when two hundred biplanes turn a small Illinois airport into the open cockpit capital of the world

Every September, Galesburg Municipal Airport in western Illinois hosts the National Stearman Fly-In, the largest gathering of Boeing Stearman biplanes in the world. Roughly 200 of these World War II-era trainers converge on the quiet prairie airfield for a week of formation flights, flour bombing competitions, restoration workshops, and the kind of grassroots aviation community that simply doesn’t exist anywhere else.

What Is the National Stearman Fly-In?

The Boeing Stearman Model 75 was the primary trainer for nearly every American military pilot who served in World War II. The Army designated it the PT-17. The Navy called it the N2S. Approximately 10,000 were built in Wichita, Kansas during the late 1930s and through the war years.

These airplanes are now pushing 90 years old — fabric wings, wooden ribs, a Continental or Lycoming radial engine up front, and an open cockpit where the wind hits at a hundred miles per hour. And every year, pilots fly them cross-country to Galesburg. Some cover 500, 600, even 700 miles in aircraft with no GPS, no autopilot, and sometimes no electrical system at all. Just a compass, a map, and a pair of goggles.

One pilot named Dale flew his 1941 Navy N2S-3 from Montana, crossing the Rockies, Wyoming, and Nebraska over three days. A Stearman cruises at roughly 95 miles per hour and needs fuel every two and a half hours. He slept under the wing one night at a grass strip in South Dakota that had no hotel within 30 miles. He called it the best sleep he’d had in years.

What Happens at the Fly-In?

The ramp at Galesburg during fly-in week is one of the most striking scenes in general aviation. Row after row of Stearmans fill the field in every color scheme imaginable — the classic blue-and-yellow Navy livery, Army olive drab, polished aluminum, red, green, and everything in between.

The variety of modifications is just as impressive. Some aircraft are bone stock, running the original Continental R-670 radial making 220 horsepower. Others carry Pratt & Whitney R-985 Wasp Juniors producing 450 horsepower, turning big fixed-pitch propellers with a sound that rattles your chest.

Flour Bombing Competition

One of the signature events is the flour bombing competition. A target circle is painted on the grass, and pilots fly over at a few hundred feet, dropping a bag of flour from the open cockpit — no bombsight, no computer, just eyeball judgment of altitude, groundspeed, and wind. The accuracy is remarkable. One veteran competitor named Sarah, with 15 years of Stearman experience, placed her flour bag within three feet of center on her first pass.

Formation Flights

Group formation flights are another highlight. A dozen or more Stearmans fly in V-formation over the Illinois countryside and downtown Galesburg. Residents line the sidewalks to watch biplanes fill the sky while the sound of radial engines echoes off the brick buildings on Main Street.

The People Behind the Biplanes

The fly-in’s real draw is its community.

Rick and Emma, a father-daughter team from Ohio, bought a basket-case Stearman when Emma was 12 — just a fuselage and a pile of parts in a barn. They spent six years rebuilding it together, every weekend and summer, sanding, stitching fabric, and overhauling the engine on the kitchen table. Emma learned to rivet before she learned to drive. She soloed in the Stearman on her 16th birthday, and at 23, she still flies to Galesburg with her father every year.

Harold, a 91-year-old veteran, trained in a Stearman at Thunderbird Field in Arizona in 1943. He no longer flies, but his grandson flew him to Galesburg in a restored PT-17 painted in the exact markings of the airplane Harold soloed in more than 80 years earlier. After they taxied in and shut down, Harold sat quietly in the front cockpit for a long moment, then turned to his grandson and said, “She still flies like a dream.”

Workshops and Stearman Maintenance Knowledge

The fly-in hosts workshops and forums led by restoration experts from across the country. Topics cover fabric covering techniques, engine overhaul procedures, and rigging adjustments specific to the Stearman’s quirks.

Key maintenance considerations for the type include:

Landing gear geometry that makes the aircraft prone to ground loops if the pilot isn’t attentive
Center section struts requiring regular inspection
Gravity-fed fuel system from a tank in the upper wing, demanding careful fuel management

Some of the experts in attendance have been maintaining Stearmans for 40 to 50 years and share their knowledge freely with anyone willing to ask.

What Are the Evenings Like?

As the sun sets over the Illinois prairie, the scene shifts from flying to fellowship. Two hundred biplanes parked on the grass glow in the fading light while pilots gather in lawn chairs under the wings. Grills fire up. Someone brings a guitar. Stories and photographs from previous fly-ins pass between old friends and new ones.

A formal banquet awards prizes for best restoration, longest distance flown, and best original condition. The evening always includes a tribute to the military pilots who trained in Stearmans before going on to fly P-51 Mustangs, F4U Corsairs, F6F Hellcats, B-24 Liberators, and B-17 Fortresses. The Stearman was where an entire generation of aviators began.

Flying into Galesburg: What Pilots Should Know

Galesburg Municipal Airport sits at approximately 764 feet MSL on flat terrain with two runways. During fly-in week, special traffic procedures are in effect to handle dozens of biplanes in the pattern simultaneously — many without functioning radios.

The CTAF gets busy. Volunteer traffic directors on the ground use signal paddles to help with parking. Expect organized chaos and plan accordingly.

Exploring the Town of Galesburg

Galesburg is the birthplace of poet Carl Sandburg and features a walkable downtown with restaurants and shops. During fly-in week, the town fully embraces the event — restaurants run Stearman-themed specials and local families open their homes to visiting pilots who need a place to stay.
