Last year at the Reno Air Races they flew. On Sunday they did their final show and I was watching them north of us and told Mrs. rktman they were headed our way. Sure enough, right down our street headed south about 500 ft. Neither one of us could get our cameras going in time. It was awesome.
She was able to snap a couple of blurry pictures, and they were gone.
I didn't know this at the time, but apparently there's an unspoken competition between the teams, to drop smoke on one another, and that's what the Thunderbirds were doing.
