There was two airplanes in http://www.imcdb.org/movie.php?id=87527

A Partenavia P.68B which had an important "role" in the movie.

There was also a Douglas Skyraider AD-4 W (Civil Registration: SE-EBB)

Please excuse the low quality of images, thought it was better tan no photos at all

This is some stuff for Impdb : can someone add it there (sixcyl?) ?
