by O. Ryan, H. Branch, and E. Warner for the Civil Aeronautics Board, Aviation Accident Report: TWA Flight 3 (1942)
“ When it became apparent to TWA's dispatcher at La Guardia Field that the visibility at the Dayton Airport had decreased below the minimums authorized, he immediately re-dispatched the flight to Toledo and in so doing provided Captain Hortman with an alternate airport at Detroit, should the visibility at Toledo fall below the minimums authorized. The fuel on board the aircraft at the time it left Pittsburgh was sufficient for the flight to proceed to any of its alternates, and remain well within the requirements of the Civil Air Regulations. ”
