A C-17 Globemaster III aircraft assigned to the 167th Airlift Wing flies above a group of vultures soaring in thermals over Argos Cement Plant in Martinsburg, W.Va., Nov. 8, 2018. The black vultures have been roosting at the plant for more than a year posing a threat to local aviation. The 167th AW has teamed up with the USDA and Argos Cement Plant to research the behaviors of the vultures to help mitigate the aviation threats. (U.S. Air National Guard photo by Senior Master Sgt.
