In Memorial

Karl D. Stoltzfus - Founder

Karl was born September 15, 1940, in Parkersburg, PA to the late Christian David and Irma Hess Stoltzfus. Karl’s father, known as “Airplane Chris,” was an aviation pioneer, and he instilled into Karl a love for all things aviation. At a young age, Karl developed a deep desire to operate a fleet of aircraft. After graduating high school, Karl began working at his father’s aviation business as a pilot and fabricator. On August 3, 1963, he married the love of his life, a young nurse named Barbara Sue Beiler.

In 1967, he and his twin brother, Ken, moved with their families to the Shenandoah Valley to attend Eastern Mennonite College, from which he graduated with a Bachelor’s degree in Business. To pay their way through school, Karl and Ken founded K & K Aircraft. Seven years later Karl and Barbara purchased Bridgewater Air Park, and K & K relocated there. This business became Dynamic Aviation in 1997.

He was an avid pilot with 6000 hours total in multiple types. His depth of knowledge regarding aircraft parts, maintenance, and modifications was unparalleled. He bought and sold many aircraft throughout the years, including the purchase of 124 King Air 90 aircraft from the US Army in 1996. In 2016, Karl led the purchase of the First Air Force One and poured his heart into the restoration process.

He was a voracious reader of both aviation and history and loved to share what he learned with everyone he met. Karl demonstrated integrity and taught others to do the job well. He taught them how to laugh, how to learn, and how to begin everything with “yes.” He had a distinct love for Jesus. His compassion and selflessness extended past the familial bounds to all those he came in contact with, and because of this, many people came to call him brother, father, or friend.
