OAP, I was once snow controller at Waddo much to the annoyingly of SATCO, and I have to say I agreed with him but orders was orders.
We worked flat out from Friday night to get an aircraft back from Goose on Sunday. MT starred first clearing the western taxiway. Two perfectly cleared strips with a two foot tall dividing barrier of ice down the centre.
Then came the ploughs, they ploughed to within 5 feet of the edge of the runway clearing the lights in the process. They couldn't be replaced until the thaw. The best was the snow blowers. They cleared 90% of the runway of ice.
The captain was informed as he made his approach. "Where is the 10% remaining?"
"All over, about a square foot of ice in every square yard."
Supply Sqn really was the best, and I mean it, they provided those arctic eye shields to protect against snow blindness and blown ice crystals. They also provided pot per mag to spray the eastern snow banks that were otherwise invisible in the late afternoon sun.
Met? CAVOK.
