Giant in the Mist

 Actually its not mist but fog since the visibility is less than 1000m. A TAP A340-300 is holding short of Lisbon's runway 21 in LVO (Low Visibility Operations). We too are holding at the lighted stopbar in front of us with A319 CS-TTP bound for a return flight to Madrid. These weather conditions require an increased separation between aircraft which is why delays are almost always associated to them.
