Norbert is in trouble.
Telling the truth obviously is not the right choice if you want to live a calm and comfortable life.
His only crime was to point out a default in a newly certified aircraft, after a first crash in 1988. The idea was to prevent other accidents, and at that time seemed pretty reasonable (and logical). It was not. He lost his job as a pilot, was put in jail, sent to psychiatry, and ruined. The lobbies won.
Today, Norbert is a tramp, has no address, no bank account, no nothing in fact. And the french administration is still after him.
A few of us, mostly ex-colleagues and friends, are trying to help him keep his head above the water. Any contribution, big or small, is helpful.
