I had to look up the Caproni ca.60. OMG. You've provided my morning's entertainment.
Calling it a bad idea is insufficient. It is like some sort of drunken assault on the laws of aerodynamics, not to mention esthetics. Those aerodynamic laws were pretty well understood by 1921, when they built the ungainly contraption, but anyone who has stood behind a wall to get out of the wind can at least suspect that those front wings are going to reduce the air flow over the middle wings, and that the rear wings will be in even worse shape.* I did about 30 seconds of research to determine that by 1921 the triplane concept was a dead duck for reasons directly related to this and this is a ....a ....is there even a word? Nonaplane? This picture suggests the designer knew this, too -- those things that look like office dividers in the rear wing must be the rudders. It looks like there are about a dozen of them! They must have built a model and quickly found out yaw was almost impossible to control without huge amounts of control surface.
It is so obviously unworkable it makes me wonder if, as I suspect SpaceX is, it was a sort of
Producers style investment scam.
Almost unbelievably, it actually achieved some sort of very brief successful flight. Once. The second time it wisely stuffed itself into the lake and that was that.
* In fact, as I look at it, the thing is actually designed to attempt to fly in its own wake turbulence.
** It is weird how much aeronautical engineering one picks up just by living for 20+ years in a Boeing engineer neighborhood!
