I think that I understand you, Whale . . . and as I possibly become sympathetic, and also while Atlas operates military charter classic's that masquerade in Polar call signs while uncompensated Polar FE's sit at home
Sorry, I've flown dozens of military flights in the last two years and have NEVER seen nor used a Polar call sign. Fantasy is a wonderful thing.
I know, I know, a friend of yours saw a Atlas plane use a Polar call sign once at RMS, but Polar is operating planes in Atlas colors, so.....?
