Remarks: Kittyhawk 733SF taxiing out to 28L on a gloomy evening. Kitthyhawk flew 2 daily 727s into SFO for years and years. When they got the 737-300SFs, they began just one daily 737 flight and started parking at the DHL Cargo Center. I never did know where they flew from SFO though, anyone want to give me a clue? In the background, one of Virgin America's first few flights arrives on the Airlines first day of operations.
