I was supposed to be flying my checkride today. It was really foggy when I got to Tradewinds at 11:30am, but the TAF’s for SJC were forecasting it burning off by 1pm. It never happened, the Pilot Examiner called me about 1:30pm and called off the flight. He’s going to call me back later with another date. I headed home really disappointed. Guess what, the fog finally cleared about 3pm, damm I should have told him to give it another hour and then see if we could fly.
