A Group of Pilots and Professionals Dedicated to STEM and Aviation Education

“We need to identify the talented and motivated students.  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.

Retired Brigadier General and F-16 Pilot, Bobbi was the first female fighter pilot selected by the Iowa Air National Guard after the law was changed in 1993.
