What is this aircraft?

[WNOE]

I followed this aircraft which had squeaked 7700 around San Antonio on 3 March 2020. It made some very strange manoeuvres. Does anyone know the circumstances and the aircraft?

TATER1 is almost certainly a USAF T-38C, flying out of Randolph AFB.

Do you have a record of the hex code?

OK, I ran playback for 3 March 2020 and found it. https://planefinder.net/flight/TATER1/time/2020-03-03T21:20:00.000Z/speed/38

The hex was AE00C9, which means that it's T-38C 65-10422, from the 435th FTS, Randolph AFB.
