Pacific Southwest Airlines Douglas DC-3

N95487, c. 1952. Ed Coates Collection. Notes: By the early 1950s Pacific Southwest Airlines was known universally as PSA.  Many passengers did not even know (or probably care) what the initals stood for.     This also was the era of the impossibly tiny registrations painted on the fin.   This DC-3 was built as a US Navy R4D-1 (BuAer 3134) and civilianized in 1948.  PSA sold it off to Piedmont Airlines as N57V.  This shot was taken at San Francisco, circa 1952.
