FWIW, I believe this WE is the USAF Heritage Flight Training. Usually about 4-5 P-51's, a P-38 and a P-47 show up, an A-1 with a couple of F-86's train with F-15's,16's,22's and 35's with their A-10C brothers. I wish the QF-4 still showed up but not since '16 when the QF-16 took it's place. Few things sound better than a Merlin at full growl or the lumbering R-2800 or 3350. I gotta admit, I feel sorry for the residents around Luke AFB with the F-35 training ramping up. They make a F-111 sound quiet! I worked them and I thought they were LOUD! I was looking forward to a long ride on the SG but this comes around once a year soo....I guess not a long ride but, a shorter local one....maybe. Oh yeah, this happens over my yard. I will take pics and video this year.
