Why are you guys getting so spun up over D-0? How many times has a flight ever been delayed because of us? It is not your job to go throw luggage... seat passengers... etc etc... why worry about it? The ONLY thing of concern that I can personally think of that might be of concern would be non revs... but other than that.. wot, me worry? When the jet is ready, we will turn on the light, and off we go.
