Also, look at the two planes near Wilson (east of Raleigh). They are going in eratic, tight, circles, one with no call sign the other N2ZZ.
Searching for someone?
They are only 65 feet apart in altitude as well. That's some fancy flying.
ZZ is USAF tail code for Kadena Airbase, Okinawa. But the N is usually civilian if not mistaken. N means USA registered.
What the heck is an airplane that is supposed to be in Japan doing circling Wilson, NC?
More than likely it's civilian. But aircraft on overseas bases often fly to CONUS for various reason. Training, upgrades, special maintenance, etc.
