A method and apparatus for reducing consequences of a bulkhead failure for a liquid methane and liquefied oxygen rocket in which the rocket has a body, an oxygen tank positioned in the body, a fuel tank positioned in the body, at least one rocket engine positioned adjacent an end of the body, a bulkhead formed in the body between the oxygen tank and the fuel tank, and a container having triethylaluminum therein. The rocket engine is adapted to mix oxygen from the oxygen tank with fuel from the fuel tank. The container of triethylaluminum is positioned between the bulkhead and the fuel tank. The fuel tank will contain liquefied natural gas therein. The oxygen tank contains liquid oxygen.
