100 years ago he went down over Poelkapelle, not the French ace with the most kills (That's Fonck) but to the French he's still the more popular Ace of WW1. In part due Fonck's reputation of arrogance and some suggestions of collaboration of Fonck during WW2, as he was linked to Petain.
He once had the upper hand over Ernst Udet when Udet's guns had jammed. But in those days they still had some notions of chivalry and he did not kill him.
Tomorrow they will fly over town with the Belgian AF, Patrouille de France and Escadrilles de Cigognes (The Storks), his old squadron.
I expect the French AF to go above and beyond for this event, it's the rememberance of their biggest hero.
Every year the French AF has a ceremony in every one of their bases where they read read Guynemer's inscription in the Panthéon in Paris.
"Dead on the field of honor, September 11, 1917. A legendary hero fallen in glory from the sky after three years of hard and incessant struggle, he will remain the purest symbol of national ideals for his indomitable tenacity of purpose, his ferocious verve and sublime gallantry. Animated by an invincible faith in victory, he has bequeathed to the French soldier an imperishable heritage which consecrates the spirit of sacrifice and will surely inspire the noblest emulation."
His old squadron currently flies one of their Mirages in rememberance colors:
This is the Guynemer monument :
My distant uncles are in running the local Guynemer comité, and i'm helping out coming night, they needed help for security of the static F16 that the Belgian AF will put on the town square..
