Over the weekend, I saw a group of old warbirds buzzing around downtown Tulsa on Saturday night around 17:30 and then again Sunday evening over Owasso. I didn't have a radio handy Saturday, but Sunday I ran into the house and set one of my portables to search the aviation band. I was fortunate enough to hear a pilot calling out a roll call for the "T-6 Flight" to check in. There were four T-6 Texans, a Yak, and I don't remember the others. I think six to eight total. I suspect that Saturday's and maybe even Sunday's flight was a familiarization flight for a patriotic flyby in honor of the Fourth of July. The frequency that they used Sunday Evening was 123.300 Mhz. If you plan on going to the fireworks display in Tulsa and plan to take your scanner, you might want to include this frequency. Please post any reception reports for confirmation.
