William McRaven: We were doing a freefall. So a static line parachute is where you hook up inside the aircraft, the freefall you jump out with a parachute on your back. So I was doing a freefall operation out in Southern California outside San Diego. And as I was descending, I noticed that there was a jumper below me on my right side and two jumpers below me on my left side. And the jumper below has got — in terms of freefall they always have the right of way. So I was watching this guy over here, and before I knew it this guy here slid underneath me, so he was probably about 500, 600 feet below me and he opened his parachute. So in relative terms, he was coming up while I was going down. So as he opened his parachute, I kind of hit his parachute. It stunned me. I rolled off him. I rolled off his parachute and was a little stunned. So I pulled my ripcord knowing that I was getting to the altitude where you needed to pull it. And the pilot chute which comes out of the back of the parachute wrapped around one leg and then the risers, the webbing that is part of the parachute wrapped around the other leg and I was falling kind of head down towards the ground. The good news was that it opened; the bad news was when it opened it essentially broke me in two. So it broke my pelvis, it broke my back, it ripped a lot of muscles out. But the good news was I did get to the ground, and they came and picked me up in an ambulance and took me to the hospital and plated me and pinned me and got me back together again.
