There is nothing like a spell of frost/snow to catch every airport out. I have seen total chaos from JFK to European airports at the first sign of snow. There is little to differentiate them.
The best cock-up that I ever took part in was one winter in the RAF. The snow came and every snow plan was actioned with some success. The ploughs plowed and the shovels shovelled; Sadly, not one aircraft moved as the only vehicle on the station that had not bee prepped for the cold...was the de-icing truck.
Without anti-freeze in the radiator, the engine block was frozen solid!
