Hi, my name is Richard J. Gross and I’m a full-time Airbus pilot and commercial drone business owner. I got into drones in 2015 when I started doing aerial photography for real estate companies. I had no idea what I was getting into at the time, but it turns out that police were called on me shortly after I started flying. They didn’t like me flying my drone near people, so they asked me to come train their officers on the rules and regulations for drones. After that, I decided to start my own drone business and teach others about the safe and responsible use of drones.
