Leon B. Spencer - Leon Spencer graduated as a glider pilot from South Plains Army Air Field, Lubbock, Texas in February 1943, Class 43-4. After surviving an aircraft accident in September 1943 he became an instructor glider pilot at Sedalia, Missouri, and Blytheville, Arkansas, both First Troop Carrier Command bases.

After retiring from the U.S. Air Force in 1964 and Motorola, Inc. in 1988, Spencer has devoted much of his time researching and writing technical papers on the Waco CG-4A combat glider. Most of his research has been in collaboration with Charles L. Day, author of Silent Ones, WWII Invasion Glider Test and Experiment, published in 2001.
Spencer compiled a book, History of the 26th Mobile Reclamation and Repair Squadron. The 26th Mobile Reclamation and Repair Squadron was based at Crookham Common, England, during World War II. The 26th was the unit in the United Kingdom that assembled most of the gliders used in the major Allied invasions, including the Normandy invasion on 6 June 1944.

Charles L. Day- As a young boy, Wilmington, Ohio native Charles L. Day watched gliders and tugs from Clinton County Army Air Field, the Glider Branch Engineering Test and Experiment base from 1942 to November 1945. Charles is a graduate of The Ohio State University, Columbus, Ohio and retired after 35 years as a traveling salesman.

In 1997, Charles' interest in the WWII glider test base was piqued by the Director of the Clinton County, Ohio Historical Society. This renewed interest resulted in the publishing of Silent Ones, WWII Invasion Glider Test & Experiment in 2001 and the continued research of the various USAAF gliders. Charles and friend, USAAF Glider Pilot, Leon Spencer have collaborated in writing several papers concerning gliders.
