Not a likely starter, but a very interesting machine. The Savoia-Marchetti S.65 has two Isotta-Fraschini engines in tandem, the pilot sitting between them.

Savoia-Marchetti S.65, entered in the 1929 Schneider Trophy contest.

AS YET UNTRIED, BUT A PROMISING EXPERIMENT: The Savoia-Marchetti S.65 has its engines in tandem, with the pilot placed between them. It appears likely that this type may be developed into a very useful speed machine.

The tandem-engined Savoia-Marchetti S.65 though originally entered was a non-starter.
