BOEING 727-200 (N7443U)

KOAK - you're not going to believe this but this series of 727 N7443U is all true. I've been going through boxes of negatives from the last 50 years and I rarely took photos at Oakland because it has few photo vantage points so I rarely went there. This day I was up to help work at the WAM Western Aerospace Museum at North Field OAK, and arrived early to I went over to the Terminal to see what I could get through shaded windows and rain. I just happened to get N7443U at the gate - believe me, this is so weird that I have N7443U in 3 different colors, I do not think I have very many others jets in 3 different colors schemes by chance, and find them all on the same day. This photo would have to have been late 1989__?... is all I have. yes, I did play the Lotto tonight and the combination on N7443U is 7-11 which has always been my lucky numbers combo...
