It was snowing that day
The issue was sheet ice under the snow. Once it was plowed, it flash froze. I would think that folk would be happy that all persons involved, were and are, concerned for the well being of the passengers!!!

Interesting. Was the Urea which is laid out after plowing/sweeping the runway not working? Usually takes about 20 minutes on the ice to see some progress. The wind even gusting at 30 knots would not blow the urea away. You seem to be in the know so i am curious.
