Memorabilia
Logbooks, manuals, instruments, propellers, signage, and ephemera from the 1920s–1940s.
A flying home for the aircraft that taught America to fly.
Every owner of a serious airplane eventually faces a particular question. Not how to keep it running, or how to insure it, or how to justify the next annual. Those are this year's questions. The deeper question is the one that arrives slowly and then will not leave: what happens to it after I am gone.
For owners of pre-1945 aircraft — the Wacos, the Travel Airs, the Stearmans, the Ryans, the Stinsons, the airframes that taught America to fly — the answer is not as easy as it ought to be.
The Smithsonian accepts very little.
Static institutional museums preserve airframes by grounding them. The aircraft is saved, in a sense, but the thing that made it itself — the smell of warm oil, the kick of the prop, the particular quiet at altitude that an open cockpit gives you — ends. It becomes an artifact. It stops being an airplane.
Auction is uncertain. A buyer might fly it, and might not. It might go to a careful collector. It might go to a foreign buyer and leave the country. It might be parted out. Heirs, in many cases, do not share the founder's interest. Probate moves the airplane on someone else's timeline, into someone else's hands, often into someone else's currency.
There is another option.
The Caldwell Collection exists, in part, to be that option. We are a flying museum. Every aircraft in the collection flies, is capable of flight, or is in restoration. The aircraft donated to the collection do not move into storage. They join nearly three dozen other aircraft in a 1943 World War II hangar at Mustang Field in El Reno, just west of Oklahoma City, where they are flown, exhibited, taken to airshows, photographed at AirVenture and Sun 'n Fun, and seen by the people for whom they were built.
The 1938 Ryan SCW in the collection's hangar was originally owned by Jerry Sass, co-founder of Oklahoma Air College — the school that built Mustang Field, the airport where the airplane now lives. After eighty years and several owners, the airframe came home. It is the rarest kind of provenance, and it is now permanent. The 1940 Culver Cadet was raced by Edna Gardner Whyte, one of the most decorated female racing pilots in American history, with a hundred and twenty-eight trophies in a career most pilots could not have flown if given a hundred and twenty-eight years. The Cadet sits in the collection as a Golden Age racing aircraft and as a piece of women's-aviation heritage, with both histories permanently attached to the airframe. Each of these stories matters because the collection refused to let the story go when the aircraft was acquired. The story is not separate from the airplane. The story is the airplane.
If your aircraft comes to The Caldwell Collection, several things happen as a matter of course. The donor's name is permanently affixed to the placard and appears in the catalog entry. Livery decisions are made in conversation with the donor and the donor's family, with the understanding that an airplane is a personal object as much as a historical one — there is usually a livery a donor wants the airplane to wear, and we want to wear it. The aircraft is restored or maintained to museum-presentation standard. The donor's family is invited to events. When the aircraft flies — at airshows, at Oshkosh, at home — it flies in the donor's livery, with the donor's name attached, in front of audiences who are told who once owned it, what it did, and what it meant.
The collection cares about provenance because provenance is what makes an airframe more than a serial number. We care about the story of the aircraft's makers — the company that built it, the engineer who drew the lines, the woman on the assembly floor who riveted the wing root. We care about the economic role its make played in the city that built it: Wichita, Buffalo, San Diego, Hartford, the Oklahoma City of the Wiley Post Aircraft Co. We care about every owner who came before, what they flew it for, where they took it, what they loved about it. We care about the pilots who learned in it, the instructors who flew it, the photographs taken of it over years and decades. The provenance file we build for each aircraft is a real document, and the aircraft is treated as the object that ties all of those people together.
There are several paths a donor can take. An outright gift produces the cleanest tax outcome and the simplest paperwork. A bargain-sale structure gives the donor cash for a portion of the appraised value and a charitable deduction for the balance — the structure by which most major airframes actually move into serious museums. A long-term loan keeps title with the donor or the family while the aircraft lives in the collection. The right path depends on the donor's situation. We will sit at a kitchen table or a hangar bench with you and your counsel and your family and find the path that fits.
The airplane will fly. Its story will be kept. Its placard will name you. Its livery will reflect your wishes. Its presence will be on display at every event the collection attends — photographed, written about, and seen by thousands of people every year for as long as the institution stands. Its future will not depend on the next probate, the next auction, the next owner who may or may not share its purpose.
If any of that sounds like the home you have been hoping to find for it, we would like to talk. A visit to the hangar. A walk through the collection. A conversation with the founder, by appointment. A decision made well, in time, in your own hand. The Caldwell Collection at Mustang Field, El Reno, Oklahoma. The hangar is open.
Tell us about your aircraft. We'll follow up personally — nothing is committed by reaching out.
Some owners are not ready to part with their airplane, and they should not have to be. A loan keeps your name on the title and still gives the airplane the one thing it most needs: to be flown, to be seen, and to have its story told. More than a dozen of the airplanes flying here today are on loan — including aircraft loaned by the Collection's own founder and by the head of its restoration shop.

Beyond aircraft, the collection seeks aviation memorabilia, archival materials, period photographs, instruments and engines, and era-appropriate vehicles that fill out the hangar scene.
Logbooks, manuals, instruments, propellers, signage, and ephemera from the 1920s–1940s.
Photographs, drawings, correspondence, and documents that deepen an aircraft's provenance file.
Fuel trucks, tugs, staff cars, and ground equipment that complete the living-hangar scene.
Period tooling and powerplants that support both display and active restoration work.
Many of the most significant airframes in serious museums arrive through planned gifts — bequests, bargain sales, charitable trusts, and long-term loans arranged with a donor's counsel and family. These structures let you decide your airplane's future on your own timeline, in your own hand, rather than leaving it to the next probate or auction.
We're glad to sit down with you and your advisors to find the path that fits — outright gift, bargain sale, bequest, or loan.
Walk the flight line and meet the crew, Tuesday through Saturday. Meetings with the founder are by appointment.
