Becoming a pilot is a fun and rewarding experience. Take your friends and family on exciting adventures! Even relatively short trips that have the potential to save you hours of driving time. For example, our Cessna 172 can make the trip to Ocean City, MD in less than 45 minutes!

A Discovery Flight, or introductory flight, provides an opportunity for someone that may never have been flying, to simply try it out. The flight will be with a certified flight instructor who will be able to answer almost any flying related questions you have. We will wear headsets to communicate during the roughly forty-five-minute flight and the instructor will encourage you to participate as much as possible, depending upon your skill and level of comfort, of course. The flight is intended to be a casual and fun introduction to flying.

We understand the problem because it was our problem too. And we formed ABSI Aerospace & Defense because we are passionate about providing a solution.
