A Navy airship rests immobile at its mooring mast, engines idle, as its crews walks forward in a floodlight's illumination.

Meanwhile the ground crew, hands in pockets against the sharp night air, idle alertly in position until they are called to the handling lines. (http://www.naval-airships.org/page-770913)
