[A strike]

Well that was not the definition in the service. A FODed engine was a Foreign Object Damaged engine since FOREVER but I guess you can have your own definition (curious, in what capacity did you work for Boeing, office somewhere?)

I did some projects at Sea-Tac airport where FOD is for the debris. I don't doubt that the military has other designations. I wonder if wildlife (like the bird strikes) have another acronym?

From the web:

“Safety on the runway is expected to improve with the installation of advanced automated technology that will ‘see’ potential dangers even at night at Seattle-Tacoma International Airport. The Port of Seattle is completing reconstruction of the center runway (16C/34C) which will also include making Sea-Tac only the second airport in the country to have a Foreign Object Debris (FOD) detection system and the first in the world to integrate detection of wildlife hazards into the system.”
