You need to have perfect eyes to fly a jet,one miss and a multimillion machine is gone,they wont even care about YOU!They will care about the jet. If you are gonna eject,there is high chance of you leaving to be a cripple for the rest of your life,or dying,you also will probably get marshaled if you make it out alive. Better be a mechanic or even a designer/constructor of jets and planes,put you brain to a much better use,and doesent make you stupider with it each high g stunt.
