US aircraft under snowstorm at Bagram airfield, Afghanistan.

First measurable snow of the 2013-2014 winter covered the U.S. aircraft based at Bagram airfield, in Afghanistan on Dec. 29, 2013.

Snow accumulated on A-10s, C-130s , C-17s, and F-16s but the snowstorm did not stop flying activities at the largest U.S. airbase in Afghanistan.
