The biplane part (Caproni ca 161) right after the "you should put on a spacesuit" comment got my notice, so I checked. Actually vaguely fascinating that in 1938 the Italians had Mario Pezzi wear an electrically heated pressurized suit [1], an airtight helmet [2][3], and sit inside of a pressure cylinder [4] to fly at 17,083 m (56,047 ft) in a propeller-powered biplane. Seems to have barely been mentioned afterward though, as it's difficult to even find imagery.
