I've about had it with them..the controllers that is. Some of them aren't good at life and have apparently been sheltered. We had a pattern full of A-10s when a Cessna just off of Tucson airport wanted to fly over the boneyard which isn't allowed. After denying the request he then said that he had a rough engine. My local controller just rogered him and went into why we can't allow civil aircraft to fly over the boneyard during wing flying. The Cessna came back with, "I have a rough engine and would like to be handed back off to Tucson." I told the coordinator to tell Tucson the Cessna had a rough engine and wanted to go back to them. Then I told the local controller to hand him off. Local, coordinator and ground control all looked at me like I was nuts for showing a sense of urgency. "What's a rough engine?" they ALL asked and said they'd never heard that phrase before. Its time to retire...again.
