I need eyes on domestic traffic.
A quick perusal of such comments on twitter is that there are apparently a number of aerial formations appearing across nations worldwide to include Canada and Germany. One person thought he was tracking a German Air Force plane approaching GITMO and then said it seemed to have disappeared from radar. All lots of curiosity and speculation with others noting they’re standard drills, etc. TBD ;)
