After the war, he started to fly a lot of gliders and even won the Siretta cup in 1947 :

In the 1950’s, Pierron was hired by the SNECMA and worked at the Centre d’Essais en Vol of Melun-Villaroche on the Emouchet SA.104 glider, that needed to be equiped with two groups of three pulso-reactors.  

He quickly got a position as a flight test engineer at the CEV in the team of Andre Turcat, the legendary flight test pilot of the Concorde.

The Nord 1500 Griffon II was a supersonic fighter prototype, developed in the 1950s in order to provide to the French Air Force a fighter capable of Mach 2 by 1960. The Griffon used mixed propulsion by turbojet and statoreactor. The turbojet allowed the aircraft to take off on its own and the stator provided the necessary thrust at high speeds that would not have allowed the weakness of the French turbojets of the time.

The Nord N262 was a French airliner developed in the early 1960s, which was used as a military aircraft (transport, crew training, maritime surveillance), particularly in the French National Navy.

Pierron was the most recognized expert in the N262 engine.

Here’s a picture of the inaugural flight of the N262, Pierron is on the top right wearing a flight jacket :

Here’s another picture taken at the Centre d’Essai en Vol in Istres in 1957 in front of the Fuga Makalu (Pierron is the fourth man starting from the left, wearing his flight jacket again) :

During this period, Pierron travelled to Japan, the USA, Canada, Madagascar,…

In 1969, he was appointed Chevalier de l’Ordre National du Mérite for serving his country:

In 1972, the Air Crew Association of the C.E.V offered him an Omega Flightmaster and had the caseback engraved on this occasion :

Later during the 1970’s, Pierron became an engineering consultant for the french firm Aérospatiale, in order to work on rotary valve engines. At the time, the Aerospatiale was developping the Concorde and Pierron participated to a test flight of the legendary Concorde n°1 in september 1977 :

After a lifetime of hard work and more than 5250 hours spent in aircrafts of all sorts, Pierron retired together with his Flightmaster, as shown on this picture taken in Tahiti in the late 1970’s :
