Have you, personally, had experience of snow clearing operations from runways?
Who me? No!
Im not knocking anyone, if that what you are implying... Its just sad news to see the airport closed and hopes it don't cause issues with easyJet at the airport!
I was hoping incidents like this could be avoided as LTN does see its fair share of closures, and I remember the chaos in February...
Also at this time of night you have all the Ryanair, Monarch and easyJet aircraft returning to base... If they divert their could be chaos in the morning wth aircraft been in the wrong location.
