At the age of 30, Glen found his passion in aviation when he received his initial pilot's license. He flew his first solo flight after only 9 hours of instruction. His love of flight led to a career with Western Airlines where he served as a Flight Simulator Instructor for Western Airlines pilots.

Glen and his wife Betsy, first purchased property in Paso Robles in 1970 but did not move there full time until four years later. Glen and Betsy established the first commercial pistachio ranch in San Luis Obispo County.

Glen Thomson, along with Betty Miller had a dream of building an aviation museum in Paso Robles. The two were very instrumental in founding the Estrella Squadron of the Confederate Air Force. Feeling compelled to do more for the community they became the initial founders of the Estrella Warbirds Museum. Last September, Glen helped celebrate the Museum's Twentieth Anniversary.

Glen Thomson was very instrumental in helping to build the museum, and will be sorely missed. His expertise in construction, aviation, power plant maintenance and his willingness to sacrifice both physically and financially, played a key roll in the success of the museum. Several years ago, Glen founded The Gooney Bird Corporation, which had a sole goal of obtaining and restoring a Douglas C-47. He realized that goal at the museum when he recently received license from the FAA to bring the C-47B "Betsy's Biscuit Bomber" to full flight status.
