Clayton Scott Aviation Collection
Contents of Collection
The Clayton Scott Aviation Collection documents the aviation career and personal life of pilot, Clayton L. Scott (CLS). This collection is comprised of textual documents and visual materials that date from 1904 to 2006.
The textual documents include flight logs, certificates, awards, membership cards, business cards, a rolodex, pilot licenses, permits, bulletins, handwritten notes, clippings, passenger ticket, correspondence, price lists, flight logs, engine logbooks, financial records, certification lists, insurance policy, invoices, receipts, hangar lease agreement, product advertisements, company letterhead, poems, travel brochures, postcards, programs, invitations, dinner menu, training materials, and CLS’s Jefferson High School yearbook. The visual materials include photographic prints, photographic negatives, slides, technical diagrams, hand-drawn illustrations, and maps.
The collection has been arranged into three series: Professional Pilot Career (1927-1961), Jobmaster Company (1919-2005), and Personal (1904-2006).
Series I. Professional Pilot Career is the smallest portion of the collection, spanning five folders. The documents within these files bring to light CLS’s pilot career throughout the Pacific Northwest region. The materials consist of 44 black-and-white photographs, 9 hand-colored photographs, correspondence, flight logs, booklet, course materials, passenger ticket, takeoff checklist, CLS business cards, and clippings.
The documents illustrate CLS's early days in the field of aviation starting in 1926 when he began working for Vern Gorst’s company, Pacific Air Transport, followed by Seattle Flying Service, Gorst Air Transport's Seattle Air Ferry, and Gorst Air Transport out Cordova, Alaska. There are photographs of CLS and other pilots from this time period, images of then Pier 3 and Pier 5 along the Seattle waterfront where Gorst ran passenger ferries. In addition, there are images of CLS’s time running ferries from Cordova Bay during the early 1930s.
Following his employment with Vern Gorst, CLS became William B. Boeing’s personal pilot from 1931 to 1944. There are only a handful of records related to this part of CLS’s pilot career. Included in the file is a Douglas DC-5 booklet that contains images of the aircraft, as well as clippings and handwritten notes adhered to the inside of the cover and a card from Boeing. In addition to the booklet, there are photographs of CLS in uniform, images of Boeing’s personal Douglas Dolphin amphibious flying boat, images of William Boeing, and a photograph of Tezzeron Lake, British Columbia, with Bertha Boeing's name written in pencil near the bottom of the image.
In 1944, CLS began working as a production test pilot for the Boeing Company. The files connected to his employment with the company include correspondence, CLS’s business cards, a flight log of his flight tests of the B-29 and B-17, training material, clippings, list of flight test personnel, and images the aircraft in flight, featured with crew members, and CLS standing in front of the aircraft.
Series II. Jobmaster Company contains both textual documents and visual materials that date from 1919 to 2005. The textual documents capture the administrative operations of the company and consist of aircraft registration, certification lists, insurance policy, correspondence, certificate, invoices, receipts, lease agreement, product advertisements, company letterhead, photograph, rolodex, and business cards. There are a small number of textual documents pertaining to floatplane conversions conducted by the company such as correspondence, conversion summaries, reports, logbooks, and technical diagrams. The remaining materials are made up of visual materials, with a total of 197 photographic prints, 53 negatives, and 10 slides. These images document the conversions conducted by the Jobmaster Company, the company’s workshop, as well as products and equipment used during projects. Some key floatplane conversions illustrated are of the Cessna 195, the de Havilland DHC-2 Beaver, and conversions of Howard DGA aircraft.
Series III. Personal makes up the bulk of the collection, with 208 photographs, 53 negatives, and 10 slides, as well as certificates, awards, a typed speech, identification records, financial records, a radio permit, pilot certification cards, clippings, correspondence, decals, membership cards, booklet of scrips, rules booklet, bulletins, invitation, programs, poems, business card, travel brochures, postcards, and a dinner menu. In addition, there are numerous handwritten notes by CLS.
The series begins with materials that bring to light aspects of CLS’s early years such images of his parents, CLS’s Boy Scotts of America membership card, and his Jefferson High School yearbook. In addition, there are materials related to CLS's father, Albert Scott, including a grocery store accounting book and personal travel notebook with pencil drawings.
The remaining materials in the series reflect upon CLS’s relationships with his wife Myrtle Irene Scott, other family members, his close friends, and his participation in aviation associations like Quiet Birdmen and the OX5 Aviation Pioneers within Seattle. The images capture candid moments of CLS’s social life, from his travels with family, his many fishing and camping adventures throughout the Pacific Northwest with other pilots like Dick Taylor, Don Knutson, and Palmer Lewis, to his CLS’s 80th, 95th, and 99th birthday celebrations with the many people in his life. There is also a sampling of aviation events that CLS attended like the World Aerobatic Championship, Oshkosh, Wisconsin in 1980.

Biographical Note: Clayton Scott
Clayton Scott was a Pacific Northwest aviator and test pilot for the Boeing Company during the early to late 20th century.
Clayton Leigh Scott (CLS) was born on July 15, 1905, in Coudersport, Pennsylvania to Minnie Laverne Clark and Albert Scott. When CLS was fifteen a barnstormer stayed on his uncle’s farm in Coudersport running passenger rides out of the hayfield. The pilot parked his Curtiss JN-4 Jenny by the house. At night CLS would sneak out to climb in the cockpit and pretend he was flying. This is when CLS first began to think about becoming a pilot. His family moved to Portland, Oregon, where CLS graduated from Jefferson High School. In 1924, while walking with his then girlfriend along the beach at Seaside, Oregon, CLS spotted a pilot giving rides in a Curtiss JN-4 Jenny. CLS and his girlfriend went up in the aircraft together. This event solidified his interest in aviation.
CLS began taking classes at the Adcox Aviation Trade School in Portland in 1925. In 1926, he began working as a field attendant and mechanic for Vern Gorst’s company, Pacific Air Transport at Pearson Field in Vancouver, Washington. It was during this time that CLS began taking flying lessons in a Waco 9. On February 25, 1927, he soloed his first flight out of Pearson Field. Gorst sold Pacific Air Transport in 1928 and established Seattle Flying Service out of Seattle, Washington. CLS followed and became an OX-5 Travel Air pilot for the company. From 1928 to 1932, CLS remained with Gorst throughout his various aviation ventures in the Pacific Northwest region. Following Seattle Flying Service, CLS worked as a pilot for Gorst Air Transport's Seattle Air Ferry and Gorst Air Transport out of Cordova, Alaska where he flew a "Boeing Boat" aircraft, as well as Keystone–Loening Amphibians. CLS flew along the Alaska frontier and was the first pilot to carry passengers across the Gulf of Alaska to Cordova on May 11, 1929.
In the early 1930s, CLS met William E. Boeing while he was refueling his commuter plane and Boeing was refueling his yacht at a marina in Alert Bay, British Columbia. The two became good friends, and Boeing soon hired CLS as his personal pilot flying a Douglas DC-5 amphibious aircraft. CLS worked for Boeing in this capacity from 1933 to 1941. During this time period, from 1933 to 1934, CLS also flew as a copilot on Boeing Model 247 aircraft for United Airlines.
In 1941, due to the beginning of World War II, CLS took on a job running production flight tests for the Boeing Company's military aircraft. He flew the B-17 Flying Fortress, B-29 Superfortress, B-47 Stratojet, B-50 Superfortress, B-52 Stratofortress, C-97 Stratofreighter, and the KC-135A Stratotanker. Later, CLS worked on Boeing’s commercial Model 700 series. CLS was the Chief Production Test Pilot for the company until his retirement in 1966.
In 1954, CLS developed an aviation business, Jobmaster Company. The company was based in Renton, Washington, with its first headquarters in a hangar that CLS built next to what is currently Renton Airport near Lake Washington. Jobmaster Company’s function was to adapt various aircraft into seaplanes through modified Edo float conversion kits. This became CLS’s sole work after retiring from Boeing but he still maintained a connection with the company. Under contract with the Boeing Company, CLS built a replica of their first airplane, the Boeing B & W, and flew it to celebrate the company's 50th anniversary.
CLS met Myrtle Irene Smith, a schoolteacher from Spokane, Washington while CLS was running passenger flights in and out of Cordova in 1930. Myrtle flew aboard one of CLS's charters on July 4, 1930 and won the distiction of being the first woman to fly across the Gulf of Alaska. The two married on October 28, 1934, in Spokane. The couple had no children together. CLS had a son, Richard Clayton Scott, who was born on December 28, 1939, in Kane, Pennsylvania. His son passed away on December 23, 1961. Myrtle Irene Scott passed away on October 2, 1998, in Mercer Island, Washington.
Clayton L. Scott passed away on September 28, 2006, at his home in Mercer Island, Washington.

Historical Note: Jobmaster Company
Jobmaster Company was an aviation business developed by Clayton Scott in 1954, although the company wasn’t formally established as a corporation with the state of Washington until 1965. The company was based out of Renton, Washington with its first headquarters in a hangar that CLS built next to what is currently Renton Airport near Lake Washington. It was when CLS retired from the Boeing Company in 1966 that the business took off.
Initially, CLS supplied modified Howard (Aircraft) DGAs as floatplanes through the addition of Edo floats but quickly expanded. CLS used his early flying experiences with floatplanes to adapt floats to a wide variety of aircraft, including the Piper Aztec, Dornier DO-28, de Havilland Beaver, de Havilland Otter, and Cessna 195. In addition, Jobmaster Company began supplying conversion kits to individuals. While the float plane, as well as conversion kits, were developed for private sale, in 1966 the Boeing Company contracted Jobmaster Company to build a replica of the Boeing B & W seaplane for Boeing’s 50th anniversary.
The main years of operation for the company were from the late 1960s until the late 1990s. Production had slowed down by the early 2000s. Upon CLS passing in 2006, the company became defunct, but it didn’t formally dissolve until 2009.

Abstract
The Clayton Scott Aviation Collection documents the career and personal life of pilot Clayton Scott (CLS). The collection contains both visual and textual materials that date from 1904 to 2006. These documents bring to light CLS’s pioneering work in the field of aviation throughout the Pacific Northwest region, beginning in the 1920s until the early 2000s. The materials illustrate his work with aviation entrepreneur Vern Gorst, his work as a private pilot of William E. Boeing, his position with the Boeing Company as a production flight test pilot, and lastly his establishment of the his aviation business, Jobmaster Company. There are also documents that reflect upon his personal life with family and friends.
Arrangement
After surveying the material, the Processing Archivist inferred that the records should be regrouped intellectually and physically into three main series: Professional Pilot Career, Jobmaster Company, and Personal. While most original folders were kept intact, the Processing Archivist imposed physical order where necessary to develop groups of related records arranged according to function or theme. Original folder titles were maintained as much as possible and are usually denoted in the inventory by quotation marks; all other folder titles have been derived by the Processing Archivist.
Custodial History
Clayton Scott willed his entire collection to The Museum of Flight prior to his passing in 2006. Museum of Flight employees documented, boxed up, and removed the collection from his office in Renton, Washington. The collection was moved to the Museum in May of 2008. A portion of the collection was stored with Bill Jepson, an employee of Jobmaster Company. Jepson donated the remainder of the collection to the Museum in 2024; those materials are maintained under accession #2024-06-05.

Processing Information
The collection was donated to The Museum of Flight in 2008, and preliminary processing was taken on by Collections Department staff in 2010. At that time, much of the collection had a variety of preservation work performed such as rehousing materials in archival-quality folders and boxes, interleaving of documents, and sleeving of some photographs. In addition to the preservation work, staff arranged parts of the collection, largely by format, and created a resource record to describe the materials. While there was a considerable amount of work done for the collection, additional rearrangement and description was still needed to align the collection organization and finding aid with professional best practices.
Therefore, in 2026, the Processing Archivist reassessed the papers for contextual information to better understand the scope of the collection and its strengths. After surveying the material, the Project Archivist inferred that the records should be regrouped intellectually and physically into three main series for a cohesive and researchable system. Elements of CLS’s original order were retained whenever possible, particularly within files, but, when necessary, related records were shifted to align with the main themes derived by the Processing Archivist.
In addition, the Processing Archivist completed any lingering preservation tasks such as sleeving the remaining photographs, negatives, and slides. Fragile paper materials were often interleaved or housed in paper enclosures.
