Volatile Fuel Vapor Recommendation
On December 17, 1963, nine days after the crash of flight 214, Leon H. Tanguay, director of the Civil Aeronautics Board (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 Bureau of Safety's successor) after the TWA Flight 800 Boeing 747 crash on July 17, 1996, with 230 fatalities, which was also determined to have been caused by the explosion of a volatile mixture inside a fuel tank.

Famous quotes containing the words volatile and/or fuel:
“The volatile truth of our words should continually betray the inadequacy of the residual statement. Their truth is instantly translated; its literal monument alone remains.”
—Henry David Thoreau (1817–1862)
“I had an old axe which nobody claimed, with which by spells in winter days, on the sunny side of the house, I played about the stumps which I had got out of my bean-field. As my driver prophesied when I was plowing, they warmed me twice,—once while I was splitting them, and again when they were on the fire, so that no fuel could give out more heat. As for the axe,... if it was dull, it was at least hung true.”
—Henry David Thoreau (1817–1862)
