Susan Horstman, CEO and Co-Founder

Susan began her flight training in Honolulu, Hawaii where she obtained her Private Pilot Certification island hopping. She later attended Embry-Riddle Aeronautical University, in Daytona Beach, Florida. There she received her Bachelor of Science in Aeronautical Science. After graduating, Susan began an extensive flight instructing career, during which she managed several flight schools throughout the mid-west. Susan culminated her flight instructing career at Flight Safety International, where she became their Chief Flight Instructor for the Cessna Citation program. Susan then moved into the aircraft manufacturing industry, where she became an experimental flight test engineer on the Cessna Citation jet for Cessna Aircraft Company. Afterwords, Susan was hired by National Airlines and became the company’s first and only female airline pilot. National merged with Pan American World Airways and, once again, Susan became that industry giant’s first female pilot. Upon the bankruptcy of Pan Am, Susan retired from the airline industry, after accruing more than 17,000 hours, in order to spend more time at home raising her son. In 2003, Susan and her son, Christon, founded Cornerstone Aviation. Acting as the active OWNER and CEO, Susan now integrates her vast knowledge and experiences to bring you the best in aviation education.

Christon Horstman, President, CFO and Co-Founder

Christon co-founded Cornerstone Aviation in 2003 with his mother, Susan. After completing both a B.S. in Finance and B.A. in Accounting at nineteen years old, Christon completed his MBA at Westminster College while still only twenty years old. Christon has accrued over 2,500 hours of flight instructing, acting as one of CSA’s senior instructors. Christon specializes in instructing advanced multi-engine, mountain flying, tailwheel and aerobatic students. In 2005, Christon was hired by ExpressJet Airlines (Continental Airline’s regional carrier). Christon upgraded to Captain on the ERJ in 2007, becoming ExpressJet’s youngest Captain at only twenty three years old. Since Christon’s first solo at sixteen years old, he has accrued over 8,000 hours of total flight time.  Christon upgraded to United Airlines in September 2013 and is now flying the Boeing 767.  Christon remains active managing CSA, while still maintaining a full airline flight schedule for United Airlines.
