Sad news indeed.
He lead a full and long life.
His name remains attached to Concorde and Air France (and Airbus by his Sud Aviation precursor)..
I cannot resist remembering how diversified and rich his life has been.
Graduating from Polytechnique (the elite maths school), he became military pilot and served during the Indochina war. He became the emblematic (and charismatic) lead test pilot of Concorde. He was often referred to as "Monsieur Concorde". These were the glorious days of Air France.
Retiring in 2006, he started a political life as Deputy Mayor of Toulouse and member of the European parliament. He married us in Toulouse.
In the 1980s he started a more intellectual/spiritual life and got a Doctorat es Lettres in 1990. He studied theology and taught history of Christian art for many years.
I am sad and wished I had such a rich life.
