2023 Board of Directors
President, Board of Directors
“We need to identify the kids with challenges – lacking confidence or motivation. Give them a comprehensive ‘mission experience’ - and help jump start their STEM or Pilot careers. Our focus should not be on quantity of students, but on the quality. Lets fill the void of a sample flight with a customized event”.
-Dave Brubaker, former USAF Fighter Pilot and STEM Flights founder.

SAM MOORE
Vice President and Secretary
Sam began flying at a young age in his uncle’s vintage Stearman. From those early days, he saw the love of flying among pilots. He also saw the great care, knowledge, and thought that went into each flight. The background and expertise in STEM and aviation was essential to each mission and to a broader and more in-depth understanding of the world. Sam believes that we are all responsible for making this knowledge and opportunity to students and youth so that they can carry it forward to the next generation.

Rick Knight
Rick found a love for flying early in life which resulted in soloing at 18 years of age. Soon after earning multiple ratings, Rick entered the military and flew the F100 and F4 for 15 years. Being an Air National Guard pilot allowed him to also fly with American Airlines where he retired after 35 years. Rick then became a Check Airman on several aircraft as well as an instructor and program developer for the Airlines Human Factors department. Had it not been for several mentors along the way, his career would not have been as fulfilling and so the values of mentorship is something he wishes to pass down. Rick says "Nothing makes me happier than inspiring young adults to throttle up."
