[by Earl Blacklock] When Canadian bush pilot Robert Gauchie left Cambridge Bay on February 2, 1967, he had every reason to be confident he would arrive in Yellowknife, less than six hours away, by late afternoon. He flew a single-engine Beaver, built to be both rugged and reliable. He had every kind of communication and navigational aid available. Just over two hours later, Gauchie encountered a driving snowstorm. When he attempted to set up an instrument course, he discovered two crucial instruments – his turn-and-bank indicator and his artificial horizon – were not working. Descending quickly, he flew by sight until he spotted a stretch of clear ice. There he set his craft down.
