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!!
There's a couple more up now. A B-752 out of Elgin looks like its headed to DC. An executive jet out of San Antonio. Another jet out of Cherry Point. Looks like the skies are slowly waking up.
