Unknown (cn Unknown) A recently acquired postcard showing 56th FIS F-86L's on the flight line at WPAFB, mid to late 1950's. WPAFB operated the F-86D's with the 97th FIS (Those markings can be found on the F-86D at the AF Museum) and then later on flew F-86L's with the 56th FIS. The 56th traded in these F-86L's for F-104's in the late 1950's.
