Foreign Object Debris. For those of you who were in an air force(any air force, not strictly the US or Canadian's) that was a vital and necessary duty before a tactical fighter squadron's jet fighters could be launched. It consists of walking from one end of the runway to the other in search of nuts, bolts, tools ANY loose objects of any size that could be easily sucked up by the jet engines... This was not to be allowed to happen because it is dangerous for the pilot and the aircraft...
Flt/Sgt speaking to plane crew: Right, you shitbirds, Listen Closely!!! Flt/Lt Scott-Lovecraft wants a fucking excellent FOD walk down or it's your asses!!!! Dismissed!
