I would like to see the transcripts from the tower and the CVR.
On defense of the FAA, I periodicly get info via email and snail mail about runway incursions and the like. Info on airport, taxiway and runway markings are provided in these briefs.
Until we get the final report from the NTSB, we should not run to blame anyone. It is bad enough the media likes to throw out headlines like: Control tower turned back on Comair departure. Talk about tasteless and useless, that is what that is.
