Even modern 0/0 seats (i.e. theoretically survivable for zero airspeed and zero altitude ejections) carry inherent risk. When I was in the military a friend of mine was killed ejecting in an emergency shortly after takeoff. You're sitting on a loaded and primed tube of explosives; there's no way to make that totally benign. Just a few days ago the Iranians lost two pilots when their ejector seats malfunctioned in a hangar and catapulted the occupants into the roof of the hangar.
