Narrative:

After takeoff on skyline departure the first officer took a turn to 170 degrees that was for another aircraft. It took us right over sfo. It turned out later that I was in the first stages of the flu and I probably wasn't as sharp as usual. I should have questioned the first officer -- the call signs were probably similar.
