Acronym for Washington DC Special Flight Restrictions Area. Excessive restrictions on General Aviation flight within 60 Nautical Miles of DC enacted temporarily after 9/11, then made permanent at the end of the Bush Administration. A useless bureaucratic circle jerk that inconveniences GA pilots while doing little to make us safer from terrorism.
Pilot #1: "Did you hear that the DC SFRA is now permanent?"
Pilot #2: "So some politicians got together and had a little circle jerk and decided that my routine GA flight is now a matter of national security based on an imagined threat?"
