The best deicing I ever heard of:
n 1991, the town gained exposure to the Western world with the inauguration of Alaska Airlines flights to the United States using McDonnell Douglas MD-80 jets. According to an anecdotal story published in the New York Times, the first Alaska Airlines flight needed deicing services, which were unavailable, so the flight crew acquired a quantity of vodka and sprayed it onto the wings[1].
