For those folks flying anywhere inside the immediate Bay Area, which is pretty much all of us, the FAA has just released information on a Presidential Temporary Flight Restriction for both Thursday, October 21 and Friday, October 22.
This TFR covers virtually the entire Bay Area and prohibits all model airplane activity from taking place, in addition to the standard restriction of GA flights and training. ย It is strongly advised that you do not attempt to fly any model aircraft during this period unless you want to spend time with the Secret Service and FAA.
For details please see the FAA TFR web site.
