On my 13th jump on student status I dislocated my shoulder in freefall - don't know how. I tried going for my ripcord and couldn't move my right arm so I went for it with my left hand and started barrel rolling... - Smart huh. My Cyprus fired @ 700 feet and I got my breaks down just before hitting the ground. I'm not sure if this counts as a malfunction since I stupidly forgot to pull my reserve - A lesson I won't soon forget :)
