Hi there
considering you don't fly and this is your 2nd post you'll be forgiven,
but had you been on freq that night especially on ground or been the pilot of the SAS down to min fuel before you'd have to go back to the gate,
OR one of the 16 odd aircraft suddenly delayed pushing back with full loads on board.
OR the ground controllers who were trying to sort out who called for push first...second etc when none of the planes could see 10ft past their noses
THEN you would have realised how all of a sudden a minor problem with 1 aircraft at the holding point leaking hydraulic fluid all over the only available taxiway and on the runway, once he went back down to vacate past the line behind.....
and once the runway had been inspected in low vis conditions at a peak arrival and departure time 2100hrs
THEN and ONLY THEN would you realise that yes it was chaos for about 2hrs trying to sort the back log out.
So i suggest that it is YOU that gets out and gets a life.
