Flight line Safety
Airmen walk in a line as they pick up trash and debris during a foreign object damage walk on the flight line of Joint Base Elmendorf-Richardson, Alaska, May 9, 2014. During a FOD Walk, Airmen spread out and walk along the air ramp, picking up any loose objects they see, such as small rocks, which can be transported onto the ramp in the tire treads of vehicles.
