I have a recollection that about 15 years ago, a snowstorm closed Heathrow Airport for an extended period. There was a huge media fuss, politicians got involved, Heathrow management had to grovel, and as a result, the airport invested in a new, larger fleet of snow-clearing equipment.
I doubt if it's turned a wheel in anger more than a handful of times in the last decade, if that ...
It's good to have snow clearing equipment available. Sure I see it at Doncaster. Even if it's not used very often, I'm glad its there.
