Yes, that was a 777 backtracking then vacating at B to Hold at A IIRC, shouldn't even have been attempted (check Google Earth) but easily fixable if required with a 'filet' of tarmac.
Was a lineup that had to clear on B to line up again on A.
Better to be safe than sorry, rather have a small delay than a big dent and a further very big delay
Fair point BUT the issue is that the rest of the airfield shouldn't have to grind to a halt once or twice daily for a scheduled flight, but they'll have all the pain of the MAN/LGW/LHR experience to learn from. There's not much room for wingtips towards Loganair, would it be an enter at E to vacate F and line up at G if they're departing 05?
