KSJC - Early 1990s shows American Airlines MD-11 N1751A *48420/451* at the hold bars at 30L for Tokyo-Narita for the apprx 1:00pm PST flight. Many times the NRT flight would sit here on the pad with engines turning for 30 minutes- only to go back to the gate and leave later. I never knew why - this all pre Internet days. photo from the old San Jose State Aviation School parking lot - I had an 8ft ladder in the back of my pickup truck to clear the fence line and GA planes parked in the foreground. N1751A was sold to FedEx in 1996 and this jet was converted to a freighter and still flying as such.
