Owner, Co-Founder & CEO
Susan Horstman, Owner, Co-Founder & CEO
Susan Horstman is the Co-Founder and CEO of Cornerstone Aviation. Susan is truly a pioneer in the airline industry. Having caught the bug of flying while she was competitively surfing and had been in two world surfing competitions, Susan received her Private Pilot in Hawaii in 1970. She decided to move to Daytona Beach, Florida and completed her Bachelor’s degree at Embry-Riddle Aeronautical University. After building her initial commercial flight experience, Susan was hired by Flight Safety International and eventually became the Chief Instructor of the Cessna Citation training program. Having so much experience in the Citation, Cessna Aircraft Company recruited Susan to become the first female Flight Test Engineer in the Citation Experimental Department.
In 1978, Susan was hired by National Airlines as a First Officer on the Boeing 727 and became the airline’s first and only female airline pilot. Some years later National was acquired by Pan American World Airways and, once again, Susan became that industry giant’s first female pilot. While at Pan Am, Susan was based in Miami, New York and Berlin. Being a trailblazer for women airline pilots, Susan became a charter member of ISA+21, the International Society of Female Airline Pilots, helping airlines develop better working conditions for female pilots which included maternity contracts, dress codes, and more. Over the years after acquiring over 22,000 hours of flight time, Susan has also been active in the 99’s and Women in Aviation, serving on a variety of committees and speaking at may events nationwide.
Having such a vast experience in general aviation and at the airlines, Susan felt the need to give back to her local aviation community and, as a result, founded CSA. She is passionate about mentoring CSA students and loves to stay in contact with students throughout their careers. Susan has made CSA a family and she is proud to help students achieve their aviation aspirations!
Founder & Chairman
Christon Horstman, Founder & Chairman of the Board
Christon Horstman co-founded Cornerstone Aviation, with his mother Susan, and was the first CSA flight instructor. Christon began flight training at 16 years old and actually passed his Private Pilot check-ride on his 17th birthday. Over the course of the next year, Christon finished the rest of his flight training and received both his Commercial Pilot and Flight Instructor licenses on his 18th birthday. In fact, the CSA training program is designed around this same training time timeline! While completing his undergraduate degree and M.B.A. at Westminster College, Christon flight instructed full time at CSA. At 20 years old, he was hired by ExpressJet Airlines as a EMB-145 First Officer and the youngest airline pilot in the company. Christon upgraded to Captain at ExpressJet immediately when he turned 23 (the ATP minimum age). Christon was then hired by United Airlines and has logged over 13,000 flight hours on airplanes including the B-777, B-767, B-757, and B-737. Christon currently flies the Boeing 777 Dreamliner from his New York base to destinations throughout the world.

Martin O’Loughlin was born in Boston, and spent most of his youth in the suburbs of Washington, D.C. He graduated from George Washington University with a Bachelor of Science in Chemistry and was later commissioned as an Officer in the United States Navy. He became an FA-18 pilot, Topgun graduate, and flew dozens of other military aircraft continuously for 20 years. Martin was the most junior pilot ever to win the Michael Hoff Attack Aviator of the Year Memorial Award. As a USAF F-16 exchange pilot, he was his squadron’s and wing’s overall Top Gun multiple times. Later, the FA-18 squadron he commanded earned distinction in combat, and was the first Hornet squadron ever to win every competitive award in the same year for personnel retention, operational efficiency, aircraft maintenance excellence, ordnance handling expertise, and safety.
In his distinguished career, Martin was awarded the Air Force Airman’s Medal for Heroism, several Meritorious Service Medals, numerous Air Medals and Aerial Achievement Medals, and many combat, deployment, and personal awards.

Martin left active duty to become the CEO of a multi-location FBO involved in the full spectrum of aviation activities – fuel sales; aircraft sales, maintenance, and rental; flight instruction; firefighting; and charter, operating more than 75 aircraft. He has had similar leadership roles with other FBO chains, aerospace companies, FAA-certified repair stations, and flight operations throughout North America and the Caribbean. Martin has founded or co-founded twelve companies, been a hands-on leader for several others as a C-Level executive, and served on university business school and charter high school Boards of Directors.
As an active pilot with over 7,000 flight hours in 100 models of aircraft, Martin has vast experience in aircraft modification, flight test, and certification. However, his greatest enjoyment comes from working with the flight instructors and aircraft technicians who are making the next generation of pilots. His recreational passions include flying, skiing, cycling, golf, and hiking in the mountains with his Golden Retrievers.
