long line of men standing along the side of a road or airport runway. The men are wearing a variety of clothing, including traditional Afghan clothing, western-style clothing, and some are wearing yellow safety vests. In the background is an airport control tower and a red fire truck. The weather appears to be overcast and the ground is wet, suggesting it has recently rained. Some of the men are standing still, while others are walking slowly along the line. The overall impression is a scene of order and organization.
