Eyerly Aircraft

How did an aircraft company become a major amusement ride manufacturer when most of their rides didn’t even look like airplanes? It all started with an aspiring pilot and lifelong tinkerer.

Born in Illinois in 1892, Lee Eyerly had a natural curiosity for machines. When he was a teenager, he and his family moved to Hobson, Montana where he found work repairing farm equipment. In 1911, he traveled to the famous Dominguez Field in California where he was introduced to many well-known aviators of the day. Since the famous first flight of the Wright Brothers in 1903, the possibilities of air travel captivated many Americans, including Eyerly. He dreamed of building and flying his own planes, but didn’t have the money to execute his plans. When he returned to Montana, he started up his own auto shop while tinkering with gliders on the side. He soon married and started a family.

A drought in the region at the time was drying up farms as well as work for a farm equipment mechanic, so Eyerly moved his family to Salem, Oregon in 1919. He started up his own business greasing and lubing automobiles while also working as a mechanic at the local Ford garage. His love for airplanes and flying led him to take flying lessons from a local barnstormer in a Curtiss Jenny airplane. After just three hours he flew the plane solo. This was all the formal training he would ever have.

He moved to nearby Waldport, Oregon for a few years. Upon moving back to Salem in 1927, he bought a little mail plane and began a flying school and airplane repair shop called the Pacific Airplane Service. At the time, his was the only airplane service station on the West Coast. Within about a year, Eyerly developed a new monoplane design that was the first modern airplane design created in Oregon. He continued modifying and developing the concept, but with the onset of the Great Depression, only two were built. However, it was the Depression that also brought about Eyerly’s biggest success.

In 1931, he put together a mechanical device for training pilots which recreated nearly every possible movement experienced while flying a real airplane. This forerunner of modern flight simulators was named the Orientator. Unfortunately, only five were ordered – all by the Cuban government.

Art McKenzie, a fellow member of the Oregon State Board of Aeronautics, saw the potential in the device as a means of entertainment. Recreation and diversion became more desirable to Americans that had grown weary from the hard times created by the Depression. Before he could fully convince Eyerly, McKenzie had already collected a long list of orders for the Orientator as an amusement ride. Eyerly set up a production line to crank out 50 rides – which had then been renamed the Acroplane.

The first moments of this short film show the Acroplane in action:

After Eyerly saw how popular the Acroplane was at carnivals and fairs, he developed the Loop-O-Plane, Roll-O-Plane and a multitude of other rides with great success. Despite the shift in products and clientele, ‘Aircraft’ remained in the company’s name.

When Disneyland was being planned, Eyerly Aircraft was approached to build a Dumbo ride based on Eyerly’s Octopus, but in the end the job was given to Arrow Development in California, which had not yet reached the level of financial stability that Eyerly Aircraft had achieved at that time.

While he may not have had success from building airplanes, aviation was still a big part of Eyerly’s life. He was instrumental in establishing and managing Salem’s airport, located right next to the Eyerly Aircraft facilities. The ranch he lived on outside of town also had an airstrip so he could easily commute to and from the office via his own private planes. Around the early 1950s, he retired and left his sons Jack and Harry in charge of the company. Lee Eyerly died of cancer at age 71 in 1963. In 2001, he was inducted into the Oregon Aviation Hall of Fame.


Lagoon has had a good amount of Eyerly rides over the years, starting with their first Roll-O-Plane in 1947. When a tragic fire destroyed half the park in 1953, new rides were needed. Three new Eyerly rides were part of the 1954 lineup – the Octopus, Rock-O-Plane and a new Roll-O-Plane. A Loop-O-Plane and a Super Roll-O-Plane were added in 1972. Bulgy The Whale, which is still part of Kiddieland after more than 60 years, is also an Eyerly ride. Incidentally, the Paratrooper was created by Frank Hrubetz who was Eyerly’s chief engineer for many years in the 1930s.

That’s awesome! Aside from what’s on my website, I’m afraid I don’t have a lot more info. You can read a little about it in this Billboard article. It explains how the Acroplane began as a pilot training device and how it got Eyerly into the amusement business. I would consider it a very important piece of the company’s history.

That’s amazing! (My great-grandfather had an Acroplane at an amusement park he owned in 1932.) I would be interested in any pics if possible. Working on a documentary.

I don’t think I’ve come across any photos, just the film clip used above. What was the name of the park your great-grandfather owned? Sounds like an interesting documentary.

Olympic Park – I went the first time on Fly-O-Plane with two vertical wings. I learned how to snap cables for a more exciting ride.

Jack Eyerly you are so missed by my mother, Kathleen Doner of Astoria, Oregon. You treated her so well and she said “you are the nicest man”.

My Mom is Lee Eyerly’s niece. She was a test rider for a ride, I think the Octopus. Her Dad worked with Lee and also invented some of his own rides. She lives with us in Lehi now. She has some interesting stories. We have a mini 4 inch metal replica of a chair possibly used for a ride.

It was great reading about Lee. Thanks.
