Volatile fuel vapor recommendation

On December 17, 1963, nine days after the crash of Flight 214, Leon H. Tanguay, director of the CAB Bureau of Safety, sent a letter to the FAA recommending several safety modifications as part of future aircraft design. One modification related specifically to volatile fuel vapors that can form inside of partly empty fuel tanks, which may be ignited by various potential ignition sources and cause an explosion. Mr. Tanguay's letter suggested reducing the volatility of the fuel/air gas mixture by introducing an inert gas, or by using air circulation. Thirty-three years later, a similar recommendation was issued by the NTSB (the CAB's successor) after the TWA Flight 800
