parabellum:
Shame it didn't happen this time then. There have been quite a few posters who have dismissed the idea of the RJ telling ground he wasn't clear, which surprises and disappoints me.
Perhaps he tried and couldn't get a word in edgewise? Or, perhaps he had bigger issues at the moment? Or, perhaps he anticipated clearing shortly?
It was a taxiway, not a runway.
Myself, I would reserve my disappointment toward the "hittee" pending all the crew and ATC interviews, and the transcript of the pertinent ATC and CVR tapes. (If the CVR tapes were still intact.)
