The Triplane Monster Plane, 1921.

A short article on a very big topic appeared in Illustrated World in June 1921.
The photo showed a remarkable plane constructed by aeronautical engineer Giovanni Caproni (1886-1957)–three planes, really.
Three triplanes were attached to a floating Pullman-like fuselage, making this the largest and heaviest aircraft ever built at that time.
It was 32′ high, 66′ long, and 130′ wide, and was made to seat 100 and make a transatlantic voyage.
This was the “Noviplano” (the Caproni Ca. 6c, and translated in the article as “Nine-plannen”), and presented itself in an impressive if not complicated manner–it was a prototype, though, and was crashed and finished on its second flight.
