Zeppelin-like rigid airship in the distance, as seen from an airplane, a typically European patchwork of fields below, and a few farm buildings.

Two biplanes in sky as seen from another airplane, one on right closer with pilot's head visible, as well as the circular blur of the propeller, one much smaller, top left. No markings on the closer plane evident, perhaps because of the lighting.

"Taken from an Aeroplane" (top) and "The Scouts" (bottom) by A. L. Hitchin, ca. 1918–19.
