Changing of the guard

While a USAF Northrop Grumman RQ-4B (reg. 09-2039, callsign FORTE12) returns to Sigonella after a mission of about 21 hours, another USAF Northrop Grumman RQ-4B leaves Sicily for the Ukraine.

Also in this case, as yesterday, both drones have the same callsign, FORTE12.

Unusual but, at this point, not so unusual.
