Captain-Commandant Fernand Maximillian Leon Jacquet was a World War I flying ace credited with seven aerial victories.

He joined the Belgian Army as a cadet in October 1907,[1][2] and was educated at the Royal Military Academy;[citation needed] he was commissioned on 25 June 1910 and then assigned to the 4ème Régt de Ligne.

[2][1] When neutral Belgium was invaded by Germany in August 1914, Jacquet flew reconnaissance missions near Namur, and reported the hazards of the encroaching Germans.

In the latter category, Jacquet bombed the Germans at Groote Hemme on 24 November 1914, and again on Christmas Eve at Beerst and Essen.

In the former, while brave men brought home the aerial photographs and reconnaissance sightings from the front, Jacquet penetrated past them to pierce deep into the German defenses, looking for a fight.

In the evening battle, they took on half a formation of ten enemy planes, and sent one down for Jacquet's second confirmed win.

On the afternoon and evening of 30 July, Jacquet and Robin clashed with a series of Germans, being credited with an LVG destroyed.

[8] Jacquet and Robin survived being shot down by anti-aircraft fire on 8 September 1916, they remaining uninjured even as their plane was demolished.

When Belgium's first fighter wing, the Groupe de Chasse was organized later that month, King Albert was insistent that Jacquet take command.

[10] Jacquet fought an indecisive combat on 3 June 1918, driving his enemy down out of control, an action which would have counted as a victory if the Belgian were flying under Royal Air Force rules.

[10] When the Germans once again invaded Belgium, at the start of World War II, Jacquet returned to his nation's service.
