No matter what time or date that it is there is always some activity even when it is minimal, but currently the closest spot with a military transponder switched on is Brazil/Europe and a US Herkie over Okinawa...........
Something is definitively up!!
A T-6A Texan is buzzing around south Florida now but that's it. I don't look every day but there are always more birds up. Hard to fathom a Texan is the only military aircraft in North America up right now.
