If everybody on this forum is united in their view that it is unacceptable to cross a red stopbar.....
I`m always surprised when I`m at LHR. During daylight, in the queue (weirdest English word BTW) for departure I see everybody crossing the holding point markings to line up long before the a/c on the runway has departed. I mean they sometimes crawl straight in the tailpipes!
Now I know that it`s all for expediting the departures, but my surprise comes from the fact that apparently during night hours it is a big nono to cross a stopbar, but during daytime it is common practice, at least at LHR. Where`s the difference?
