During Seafair on the Sunday, I was up the tower watching the departing and returning performers. For much of the time, a Temporary Flight Restriction or TFR was in effect which meant that no one was flying in the area other than the performers. There was a part of the schedule in the middle of the afternoon that did not involve the high-performance aircraft and, during this time, the TFR was suspended so aircraft could get in or out of Boeing Field.
It was rush-hour at the airport. The first arrivals showed up and seemed to be diving for the runway. Others had been waiting to get out, so they were firing up and taxiing for departure. We had a steady stream of smaller planes and corporate jets making their moves. I don’t know whether the arriving planes had been holding somewhere or had just timed their arrivals well. Whatever it was, it seemed that everything got moved in or out smoothly before the next fast jet display was on the schedule and the TFR was reintroduced.
