As ex ATC FACT, now drifter of the world, I remember an incident in 1993 when 01/19 fell apart during a Black South Easter with serious rain and wind. Work had been done on the Rwy centre line lights and the contractors had stuffed it and huge pieces of tar were lifting about 100m from the 34 intersection. Rwy was closed from, if memory serves, about 1600 on the Sunday till early the next morning and needless to say, as it was the good od DCA then, all manner of excuses/blaming done similar to what I read now and the airlines and paying public were left carrying the can. Sooooooo glad to see all has changed - not!
