Yes. Most of 'em.
Most squadrons had 1 or 2 star scorers at any given time; maybe half a dozen at most throughout the war. That goes for Germans and Allies alike. The Germans tended to give their top guns the best and latest equipment available so that they could continue to mount their victories. The British and French awarded "roving" commissions for their stars to wander the skies at will in search of easy prey. Germany, France and England (to a lesser extent) all tried to concentrate their top pilots into single units and send them to the hot areas of action.
Having more than 1 or 2 aces in any squadron at any given time was a rarity... having half or more of the pilots in any given squadron with even a single confirmed victory was even more rare. The average pilot in WWI, IMHO, did not score a single confirmed DES kill.
Maybe that's why it rubs me the wrong way to hear any particular ace getting defrocked. Whether or not you liked his style, having any of the aces on your tail - even the so-called minor aces - was a virtual death sentence.
Howard Burdick of the 17th was a great example. "Only" 8 kills, but a brilliant flyer and an outstanding man to have on your wing. Drop your D7 in front of Burdick's Camel and you had about 10 seconds to live. Shooting down aircraft in WWI (DES, not OOC) was not a simple task, and very few had the knack.
