So there they were, rocketing towards a jagged metal resting place by way of fiery explosion, trying to find a flat surface to write on. Then, just as impact seemed imminent, the pilot said, "LOLZ, just kidding about that emergency, folks" and righted the plane. Once safely back on the ground, we like to think the soldiers showed their appreciation for this fine joke by repeatedly sodomizing the pilot with their rifles.
What was the point? To see how extreme stress affected a person's "cognitive ability," measured in this case as the ability to do paperwork.
Also, we might as well test out the new puke bags.
In a revelation that surprised no one ever in the history of anything, researchers determined that errors in cognitive reasoning occur more often if a person is being exposed to unusually high levels of stress. So under no circumstances should you whip out a job application in the middle of a car accident or attempt to file a tax return while being stabbed to death.
It's worth noting that the researchers were unable to repeat the experiment because the soldiers involved had written warnings to future subjects on the plane's airsick bags. The only option at that point would have been to collect all the bags and then crash the plane for real. Which they probably would have done, if they could figure out how to make sure the paperwork survived.
