Reason Heathrow open and Gatwick closed is obvious when you consider the weather. There was heavy snow over southeast England but virtually none around Heathrow. Simple - not rocket science!
Ha ha.
This is not heavy snow, please get a grip.
]All over the world airports close because it is difficult to clear.
This is true, but it is the speed of recovery that is telling. The UK is very good at making excuses, this snow should have been cleared quickly, but no, the airport is closed for a long time.
If you watch the snow ploughs in the video, they are clearing it easily and the roads have self cleared.
Just more excuses from a country that cannot manage normal winter conditions and prefers to wimp out.
