En-Route
Yesterday while on a x/c with a private student, we crossed paths with a flight of C130 about 500' above us. While the C130s passed by our right wing the lead aircraft flashed a red light at us several times.
Several of the other CFIs have noticed the same time lately. Is this a new way of communicating with civilian aircraft or is the flight crew just messing with the passing aircraft?
