The 27th successfully brought down four enemy balloons, and an advance flight also moved forward to an airdrome west of Verdun. It was at this time, the actions of Lt. Frank Luke were at their height. Each day, he attacked balloons at dawn and dusk and in one instance he shot down three balloons in less than 10 minutes time. In addition to the balloons, he also shot down an enemy biplane and a Fokker. However, on 28 September he was reported missing, and unfortunately was confirmed to be killed about a month later.
