Here's an old Luce film (video) celebrating the 19th Anniversary of the Regia Aeronautica in Rome. The celebrations took place on August 1942. Japanese and German officials are present and there's also a fly-over by three P.108Bs. Also, there are some very young cadets marching, in fact they march better than adults I've seen in other films! The beginning of the video is mostly (common) footage from other films of the time so you may want to skip to 1:30min when Mussolini begins awarding medals to family members of lost pilots and personnel. Mario de Bernardi is also present to receive a medal. The video is 6 mins long.
