On Saturday, 28 July 1945, Lieutenant Colonel William F. Smith lost his way while ferrying a 457th North American B-25 Mitchell bomber from Bedford Army Air Base to Sioux Falls via Newark Airport. Emerging from low cloud at about Smith found himself among the skyscrapers of Midtown Manhattan. His aircraft crashed headlong into the 79th floor level of the Empire State Building, killing Smith, two passengers and eleven office workers. The B-25 exploded on impact spraying burning fuel into 34th Street below, one of the engines completely passing through the building and out the other side.
