I was letting down for a landing at Class B International in good VFR. The flight had been rather dull—my favorite—until a Learjet 60 reported airborne off a nearby nontowered airport. They were looking for their IFR clearance to a destination in the next state north.
After the usual “say again your callsign” back and forth, the controller determined there was no flight plan on file. A new voice from the Learjet, probably the captain, asked if he could air-file over the ATC frequency. The controller instead suggested the Lear could file its flight plan over the radio by talking to Flight Service. This is when it got interesting: The Learjet then asked for the Flight Service frequency and a clearance to 17,500 feet. It got even more interesting when ATC suggested calling Flight Service on 122.1 MHz. All of a sudden, here were three blatant examples of poor airmanship and incomplete knowledge.
