On top of the terminal building together with some other aircraft. This aircraft now resides at Hermeskeil.

Part of an aircraft collection on the terminal roof

scanned from slide , when the roof terrace at Frankfurt house various aircraft

The "N" was later removed (see here). Ex LN-KLV Nor-Fly. Purchased by a private individual early August 1976 and displayed on the spectators roof terrace. So it couldn't have long been there when I took this shot. When that spectators terrace closed down the aircraft was moved to the Visitors Park at Munich Airport and was painted as HB-IRN. Still there as of 2019. I took a photo of this aircraft still in active service as LN-KLV in July 1975 (see here).

Ex-OH-VKA, OY-KLE, OY-DCA, NC34989, 41-20058. Later N65371, "N569R", "HB-IRN"

Built in March 1939 for Alpar as HB-AME. Merged into Swissair 10.47 and later HB-APE. D-IGUN from April 1969. Displayed on the FRA terminal roof in the mid 1970s.

This was part of the Air Classic collection on the roof of a terminal at Frankfurt. It was moved to Düsseldorf in Aug 1976, then to Marl in 1985 and was finally broken up for spares in the early 1990s by Josef Koch, for the restoration of his D-ILIT (cn 6879).

This aircraft was a part of an open-air museum on the roof of the terminal. I have never properly identified it
