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!!
First time I have seen it, low activity certainly, but not nothing, I usually check flight activity for a minute a few times a day and I'm in a different time-zone so that usually means night/morning/afternoon in the US..
What do you think it could mean ?
