Four engine airplane

In 1913, the first four-engine airplane was first built and flown by Igor Sikorsky of Russia.  In 1910, Sikorsky was involved in a plane crash in a single engine plane when the motor died.  This convinced him that there needed to be more than one engine in case of failure.  The Bolshoi Baltisky was built with four engines and Sikorsky flew it successfully on May 13, 1913.  In recognition of his accomplishment, he was awarded an honorary degree in engineering by the Saint Petersburg Polytechnical Institute.
