Interesting overview of SFO in 1948, taken from the 1937 terminal building towards the old hangars with the little tower still perched on Hangar 1. Hangar 4 stood until 1999. There's a Grumman G-73 Mallard in front of Hangar 3, a Constellation, and a bunch of demobbed WWII training aircraft. We made a crop for the C-47, NC63440. Note the United Air Lines air freight pick-up and delivery booth in the foreground. Photo from: SFO Museum
