Olson also developed and sold Winglet and Performance enhancement systems for Boeing 727 and 737 aircraft and the ballistic proof cockpit security doors. Olson was also a Captain in U.S. Air Force and a recognized expert in global flight support services. Craig Stewart, President of Butler National's Aerospace Division said, "This is another step in our three-prong aerospace growth strategy that includes our rapidly growing small and medium aircraft MRO business, mergers and acquisitions, and new growth. Mr. Olson will focus on the commercial aircraft marketplace. Mr. Olson brings another strong presence in the air transport business." Olson added, "I agree that Butler National is one of the fastest growing companies in the aerospace industry. They are well positioned to leverage the expected $3.2 trillion growth in the aerospace market.
