Happy 4th of July!. Im at work now but I got two flyovers today while at home. One flight was a flight of 5 Nanchang CJ-6s and the other flight was a flight of 6 RVs. All of these were streaming smoke as they flew over the Nixon Library. I live about 1 mile from the library. As it turned out, I recognized one aircraft from each flight. Both are my hangar neighbors at Chino just a few doors down in either direction.
