First it's and airforce jet, so no arresting gear/tailhook and wimpy gear, i'm amazed that landing that fast he held it to the end of the runway. Think the rule in navy/marines is 2 ejections then medical eval and if you pass you can fly but if you have a 3rd your done. I was one of the instructors that helped write the training program for the N.A.C.E.S system and it's much better than the ole F4U spine crusher. The one thing you have to remember is anytime you are forcefully removed from a fixed position your going to suffer some type of injury. It can be as simple as spine compression to dislocated shoulders, broken bones, ect.. The 1 ejection i witnessed happened on takeoff, the trainee pilot and instructor in the F18 ejected on takeoff roll halfway down the runway. The instructor was in rear c/p and got almost 3 swings from his chute, hit the pavement and broke his leg. The traineee in the fwd c/p got about 3 1/2 swings from his chute hit pavement and walked away sore and bruised.
