gangloading
 n.— «Yesterday I joined 14 students in the altitude training chamber at the Eighty-ninth Physiological Training Flight at Andrews Air Force Base in Camp Springs, Maryland. Wearing helmets and oxygen masks that covered everything but our eyes, we were there to see how our bodies would react to oxygen deprivation. The altitude chamber simulates flight to 25,000 feet, at which point you’re instructed to remove your mask and try to complete a series of tests, such as writing your name, solving a maze, and computing multiplication problems.…I put myself back on oxygen fairly soon (it’s called “gangloading” in Air Force parlance), but some in our group stuck it out the three minutes of useful consciousness to see how they’d fare.» —“Into thin air” by Jill W.
