Caproni was aware of the safety problems connected to passenger flights, such concerns being the root of Douhet's criticism. So, he concentrated on both improving the aircraft's reliability and minimizing the damage that could be caused by possible accidents. First of all, he conceived his large seaplane as a multi-engine aircraft featuring enough motors to allow it to keep flying even in case of the failure of one or more of them. He also considered (but then discarded) the opportunity of providing the aircraft with "backup engines" that could be shut off once the cruise altitude had been reached and only restarted in case of emergency. The seaplane configuration assured the capability of performing relatively safe and easy emergency water landings on virtually any water surface calm and large enough. Moreover, Caproni intended to improve the comfort of the passengers by increasing the cruise altitude, which he meant to achieve with turbochargers and variable-pitch propellers (such devices could compensate for the loss of power output of the engines at high altitude).
