is the enigma of WW1 aviation. Usually described as a boastful opportunist unpopular with his comrades he also has been characterized as a man of high intelligence and quiet to the point of seeming shy. My guess is that these are probably two sides of the same coin. A matter of perspective. It has been suggested that on occasion Fonck bullied other pilots out of claims. Fact? Fiction born out of dislike and/or jealousy? I certainly don't know and from what I have been able to read, discuss, and not least glean from the forum I am not sure any living person has the answer.
Fonck's autobiography, published in the U.S. with the title "Ace of Ace's" is thin on detail and large on ME. From what I understand it was written (ghost-written?) as self-promotional material at a point in which Fonck was dabbling in politics.
Look in the forum's aces section and see the signature descriptions attributed to Fonck by his flying peers and himself to get an idea of the complexity of the man.
Fonck would make an excellent research project that attempted to clear up the confusion related to his place in Great War aviation as well as to who exactly was this man. Unfortunately as rammjaeger pointed out that opportunity, if it ever exsisted may have been lost.
