A career Army officer I once met was jumpmaster for his unit and was taking up a few novices for a drop. The flight was pretty rough, and after a while, the jumpmaster called off the jump because of high winds. As the plane headed back to base, and the pilot pulled off an unusually smooth landing, two of the neophytes got airsick.
"How come you could take that rough flight, but you couldn't handle the smooth landing?" asked the jumpmaster.
"Well, sir," one trainee explained, "We've always jumped out of planes. We've never actually landed before."
