In the afternoon, I move on to Sr. Airman Shawn O'Day for parachute and survival training. If I have to eject from the U-2, I will stay attached to the seat until 15,000 feet. At that point, the seat will separate, and the work begins. I learn how to deal with fouled lines, a partially inflated canopy, an inverted lobe, and holes in the canopy fabric. O'Day stresses that I can only cut away a total of six tangled lines. I dutifully note the restrictions, even as a piece of my brain decides that if I find myself putting this plan into action, the "six line" restriction is going to be the least of my problems.
