I've been told a great story about a guy training who had a Condor flight (CFG) coming into his airspace. The trainee, who hadn't seen the designator before, rightly started asking people what it was. The guy sitting next to him didn't hesitate with the reply of "That's called Cargo-flugen".
For the couple of hundred miles of airspace, Condor was operating under the new callsign Cargo-flugen ............
