NASA crews today took the Columbia through a simulated countdown after a two hour delay due to a fuel leak. The test, in which both the oxygen and hydrogen sections of the external tank were to be filled with super-cold liquid fuels, was instead carried out with only the oxygen tank filled with liquid oxygen and the hydrogen tank filled with gaseous hydrogen; the problem was due to a leak in a hydrogen fuel line.
