Aviation enthusiast here…that distinct whistling is the T1-A…they had two doing night hours tonight.

If you ever want to know what 99% of planes overhead are go to www.globe.adsbexchange.com. They don’t filter out military (fighters are rarely seen) or LADD opt out biz jets…FR24 and others filter that out. VANDY is there normal call sign from Vance if a T1.

We actually get a surprising amount of military traffic here…rarely fighters/bombers but I did see a 767 variant refueler for the first time ever this past week…at about 2000’ over town.
