Sentimental Journey to Cub Haven and the Piper Cubs that come home to Lock Haven every June

Every June, hundreds of Piper Cubs return to Lock Haven, Pennsylvania—the town where the Piper Aircraft Corporation built over 30,000 Cubs starting in 1937. The annual Sentimental Journey to Cub Haven fly-in is not an airshow with military jets and pyrotechnics. It is a pilgrimage, a homecoming for the airplane that taught America to fly, held at the field that bears the company founder’s name: William T. Piper Memorial Airport (PHD).

What Makes Sentimental Journey to Cub Haven Different?

Lock Haven sits along the West Branch of the Susquehanna River, surrounded by Appalachian ridgelines. The approach into Piper Memorial threads through river valleys with green ridges on either side before the field opens up below—a sea of yellow on the ramp, the grass, and the taxiway.

The fly-in is organized by the Sentimental Journey to Cub Haven Committee and has been running for decades. Piper owners from across North America fly their low-and-slow machines hundreds of miles to reach the birthplace of the Cub. One couple flew their 1946 J-3 Cub over 700 miles from southern Alabama—in an airplane with no electrical system, no starter, and a cruise speed of roughly 75 miles per hour. They camped under the wing at three grass strips along the way. It took three days.

That kind of journey defines the spirit of this event. It is not about speed, new avionics, or the fanciest airplane. It is about the joy of simple flight.

The J-3 Cub: The Airplane That Democratized Flight

The J-3 Cub is the Model T of aviation. During World War II, thousands of military pilots got their first stick time in a tandem-cockpit Cub painted olive drab and designated the L-4 Grasshopper. After the war, surplus Cubs flooded the civilian market and trained an entire generation of private pilots.

The “J” in J-3 stands for Walter Jamouneau, the young engineer who redesigned the earlier Taylor Cub into the icon we know today. He rounded the fuselage, redesigned the tail, widened the cockpit, and created what may be the most recognizable silhouette in general aviation.

Flying in one is an experience no modern cockpit can replicate. The instrument panel holds roughly four instruments: airspeed, altimeter, tachometer, and oil pressure. No GPS. No radio. No transponder. The Continental 65-horsepower engine is hand-propped. The airplane lifts off in about 200 feet and climbs at around 500 feet per minute. Both halves of the split door can open independently, leaving nothing between pilot and sky at 60 miles per hour. You do not ride in a Cub. You wear it.

What Airplanes Show Up at Lock Haven?

The fly-in is not limited to J-3s. Every Piper model that came through the Lock Haven factory is represented:

• Super Cubs (PA-18) — the backcountry version with a 150-horsepower Lycoming engine, some rigged with tundra tires and full bush modifications
• PA-12 Super Cruisers — the three-seat variant
• PA-20 Pacers and PA-22 Tri-Pacers — the tricycle-gear evolution
• L-4 Grasshoppers — military Cubs in olive drab with invasion stripes, some confirmed to have flown over Normandy on D-Day spotting artillery

One L-4 on display carried tiny American flag stickers along the cowling marking its combat missions. Its owner traced the serial number to service with the Ninth Air Force in France in 1944. He bought it from a crop duster in Mississippi in 1987 for $4,000. Today, a comparable aircraft sells for $60,000 to $80,000.

The Restorations Are Works of Art

The judging area showcases restoration work that borders on obsessive devotion. One 1938 J-2 Cub looked factory-fresh after a six-year rebuild. The owner found it in an Ohio barn with birds nesting in the engine cowling. Every rib, fitting, and piece of hardware was inspected and rebuilt. The airplane was recovered in Grade A cotton fabric with hand-stitched rib lacing, the paint mixed to match original 1938 Piper factory color specifications.

A young woman named Mackenzie, roughly 25 years old, stood out—covered in yellow paint and dope, mid-way through her first full Cub restoration. She bought a project (essentially a pile of tubes and parts) from an estate sale for $800. She is learning fabric work from a retired A&P mechanic. She does not yet have her pilot’s license. The plan: restore the airplane first, then learn to fly in it—soloing in a machine she built with her own hands.

The Mass Formation Flight

One of the signature events is the mass formation flight, where organizers try to put as many Cubs airborne over the field at once as possible. Previous years have exceeded 100 aircraft. From the ground, it is a giant lazy orbit of yellow and black—a low, harmonious hum filling the sky like a swarm of bees. No smoke, no afterburners. Just simple airplanes and the people who love them, circling over the town where they were born.

The Piper Aviation Museum

The Piper Aviation Museum is housed in the original Piper factory building in Lock Haven and is open year-round. During the fly-in, the museum sets up exhibits including original production records, engineering drawings, and factory-floor photographs.

The collection documents the factory’s wartime production pace—roughly 20 airplanes per day on a round-the-clock schedule—and features photographs of Cubs stacked on train cars bound for military bases. A striking aerial photo captures the 1936 flood that nearly destroyed the operation when the Susquehanna River overtopped its banks. Piper rebuilt and continued.

Permanent displays include a fully restored J-3 hanging from the ceiling, a Super Cub, original factory tooling, and an extensive archive. For anyone interested in the history of personal aviation in America, this museum is essential.

Practical Information for Pilots and Visitors

• Airport: William T. Piper Memorial Airport, identifier PHD
• Runway: 4,000 feet of asphalt
• Parking: Grass parking area established during the fly-in with a dedicated Cub arrival frequency
• Non-Pipers welcome: Cessnas, Beechcraft, and everything else park alongside the Cubs
• Lodging: Hotels fill up fast—book early. Camping under the wing on the field is the authentic Cub Haven experience.
• Lock Haven is small and walkable, and the town fully embraces the event
• Pancake breakfast: Run by the local volunteer fire company in a hangar on the field. $8 for all-you-can-eat pancakes, sausage, eggs, and coffee, eaten on hay bales while overlooking rows of Cubs as morning mist lifts off the river valley.

Vendors at the fly-in sell hand-sewn leather helmet and goggle sets for open-cockpit flying, fabric supplies (Poly-Fiber, Ceconite), and original Piper factory new-old-stock parts—Cleveland brake assemblies still in wax paper, Sensenich wooden propellers still in their crates—inventory that scattered to garages across Pennsylvania when Piper closed Lock Haven operations in 1984 and moved to Vero Beach, Florida.
