Italian Giant

The Caproni Ca.90 was a prototype Italian heavy bomber designed and built by Caproni. When it first flew in 1929 it was the largest aircraft in the world.
A six-engined inverted sesquiplane the Caproni Ca.90 was designed as a heavy bomber and first flew in 1929. It had two tandem pairs of 1,000 hp (746 kW) Isotta-Fraschini Asso inline piston engines mounted above the lower wing, each pair drove a four-bladed pusher and a two-bladed tractor propeller. Another pair of engines was mounted above the fuselage.
Only one Ca.90 was built. Although the Dornier Do X flying boat that flew later in 1929 had a larger wingspan and weight it remained the largest landplane until the arrival of the Tupolev ANT-20 in 1934.
