In the bad designed today's effective aricraft, the system puts pilots between brackets before he is sitting in the cockpit . The system is "MASTER" in the effective aircraft , and the pilot is "SLAVE" . ECAM throws him biscuits to keep him busy .

In the 8 billions Ariane 501 crash (Arianespace 4.june1996) the initial condition had been added, to compute the ground position of the rocket. At take-off the bug needed only 37 seconds to show it was the master of the rocket.
The perfect inquiry conducted by Jacques-Louis LIONS finished in less than 24 hours, written in 15 days, published in 6 weeks, showed that in computer systems we must not trust the system if we see no failures, but we must take it for faulty so long we have not been able to Proof it is safe, with all the best knowlege at this time.
