San Francisco Airport Commission Aviation Library and Louis A. Turpen Aviation Museum
Set up in what the airport looked like in the 1930s, this museum focuses on the development of aviation on the West Coast of the U.S. and around the world, including aircraft mockups, pins, posters, even safety cards and luggage labels reflecting the old glory of the airline industry.
SkyTerrace is a plane spotting area. An outside area has seating facing the planes without a cover overhead for inclement weather. An indoor area has exhibits on the SFO's history and some additional seating.
The SkyTerrace is before the main security checkpoint are in Terminal 2, though the SkyTerrace has its own security check where visitors walk through a scanner and a guard inspects bags.
