Guynemer was one of the great pioneers of aerial warfare with 53 victories, some of his most notable in the skies above Poelkapelle. It was here that he disappeared on 11 September 1917 during a routine mission. His body was never recovered.

The highlight of the pavilion is a replica of the Morane-Saulnier. This replica has been constructed by the students of the Technical College in Ypres (VTI Ieper) and is a reproduction of the aircraft in which Georges Guynemer attained numerous victories.
