An overview of the U-2 ejection system from a
Flying magazine article:
The U-2's ejection system is not as automated or advanced as those used in most fighter jets. Whatever direction you're pointed in when you eject is where you're going to go. And since you're wearing 130 pounds of extra equipment, the rocket that propels you there is bigger than normal, generating a force of 11 to 20 Gs. The parachute is bigger as well, with a bulb-like shape. Oh, yeah. And since the U-2 is a manual airplane, don't expect the pilot to hit that ejection button for you. You're on your own -- which is why the Air Force goes to all this trouble to train you in getting yourself out of the plane in an emergency.
We progress to an egress simulator, where I don a harness and helmet and learn how I can get myself out of the airplane, space suit and all, in case we end up on the ground but away from Beale. There are a couple of "automated" handles that disconnect me from all my various safety and life support equipment. But if they fail, I have to know how to manually disconnect myself from 10 different systems and restraining devices. Hartzler closes the canopy and tilts the plane 45 degrees on its side. U-2 pilots have to get themselves disentangled from the plane in less than 60 seconds. Seconds and then minutes tick by as I struggle to release air hoses, latches and safety cables. I'm successful, but I conclude that if the airplane really crash lands and catches fire, I'm probably going to burn up with it. Hartlzer assures me that adrenaline will kick in and improve my time dramatically.
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.
I learn how I must then gain canopy control and steer the chute toward an appropriate landing site, into the wind and away from obstacles and trees. All that while opening my visor, closing my UCD valve, separating my communication cord, disconnecting my suit vent hose, removing my boot spur cables, and releasing my seat kit from my backside.
Piece of cake.
We practice the last bit of the descent and how to land properly, with feet and legs together and a rolling fall to the downwind side. O'Day then puts me in a harness and has me practice getting myself out of a 150-foot-tall tree with a PLD (Personnel Lowering Device), in case I don't quite manage to successfully implement the "land away from obstacles and trees" instruction.
