In the modern world is it not amazing that a busy international airport like Heathrow who has just spent 6 million pounds on de-icing and snow moving equipment is still shut except for a few flights leaving today? Of course planes shouldn't fly if it could be dangerous but surely this situation shouldn't haven't arisen as we haven't had that much snow yet.
PS Thank you to all the people that worked through last night trying to clear the runways etc.
