Yesterday, April 8, I heard a flight of F-16s take off from Selfridge using the call-sign "Mazda". Any info on where they are based? I did see them return later in the afternoon. Mazda flight consisted of 6 planes.
Mazda is a deployment callsign typically used by USAF fighters crossing the Atlantic and isn't tied to any one unit.
Did you happen to hear a Tanker, perhaps using the callsign Gold or Blue?
