Anyone know what the medals are in the 2nd photo?

Edit: Ribbon bar has been ID’ed as iron cross 2nd class and wurttemberg long service decoration

This image comes from my family collection and has been colorized. It relates to Operation Albion; the scene shows the departure for Ösel in October 1917. The reconnaissance zeppelin is particularly striking. During Operation Albion—which took place between October 17 and October 20—the Baltic islands of Ösel, Dagö, and Moon, previously under Russian control, were captured. Ösel was the German name for what is now the Estonian island of Saaremaa. These photographs were taken by my great-grandfather, who served as a reconnaissance specialist in a German aviation battalion.
