Every time I read about a FOD walk I’m always amazed at how much stuff they find (usually the Air Force are happy to write about what they find).
To show the importance of conducting a FOD walk, Hood, Sigala and Llerena coordinated a base-wide FOD walk. Each of the classes — more than 100 airmen from the 571st MSAS and Honduran Air Force — participated and collected more than 50 pounds of FOD from the flightline.
