In a Thunder storm OUR activity before Verdun was disturbed in the summer of 1916 by frequent thunderstorms.
Nothing is more disagreeable for flying men than to have to go through a thunderstorm.
In the Battle of the Somme a whole English flying squadron came down behind our lines and became prisoners of war because they had been surprised by a thunderstorm. During the whole day thunder was in the air. From my base at Mont I had flown over to the fortress of Metz, nearby, in order to look after various things. During my return journey I had an adventure. I was at the aerodrome of Metz and intended to return to my own quarters.
