Indeed, I do want air support like you have artillery support. I have a few books about 1914 and 1915 written in 1915 and 1916. They are speaking about the great impact of airplanes, and their expectations that it will be the most important weapon in wars to come. They are especcially very positive about the German 'Teube' and are speaking about its effect on especcially the Galicia area, but also in northern France. They claim that without the Teube's the Germans and Austrians would have lost the battles for Galicia and that would have meant an early end to the Austrian activity in the war. As it was now, it was 3 times very close, and only the 4th Russian attempt was a major failure. The book is about the history of the Great war, and is about as close to the period you can get, except for diaries, in which is spoken about the great fear for the planes as well. So, I do dare to claim that at the places where airplanes where used during WWI it was more effective then artillery. Artillery was only so well known because it was used much more often, but still the airplanes impacted WWI.
