I live about 19 miles from the airport. Today I flew at an early time than I normally do. ADS-B on the MA2 alerted me 3 times as morning departures were head out from my regional airport. I followed the aircraft on the FLY app and watched it pin point the aircraft as they flew over one an a time. I was just taking off with the MA2 when I got the first warning. I stopped and hovered at 50 feet so that I could track the commercial flights as they passed over head. I know it is a simple technology but it just amazes me how it all just works.
