On this day (April 29th, 1903) Frank Slide

Frank, NWT (now Alberta) thrived because of its coal mine, a prosperous enterprise that ripped deep seams into the mountain that loomed over the town. At 4:10 a.m. on April 29,1903, the side of the mountain unexpectedly disintegrated, depositing 90,000,000 tons of debris on the sleeping people of Frank, and claiming 76 lives. In some cases, entire families were destroyed with their residences, while others on the edge of the devastation lost only 1 or 2 of their family members. Miraculously, a whole shift of miners in the mountain survived, 1 rushing home to find that his wife and 5 children had perished in the slide.

On this day: Red River Flood (April 15, 1950)

The city of Winnipeg is built at the confluence of two rivers, and every so often the Assiniboine and Red overflow their banks and transform the city into a disaster zone. Although only one person has ever died as a result of the floods - a volunteer pump operator in the 1950 flood - these events have deeply marked the city of Winnipeg and its residents. The 1950 flood was caused by heavy snow cover and sustained for 51 days by heavy rain in May. In low-lying areas the water actually reached a depth of nearly 15 feet, covering a full one tenth of the city in water. In 1965 the city built the Red River Floodway to divert the worst of future floods, but in 1997 even those safety measures could

On this day: The Moose Jaw Air Crash (April 8th, 1954)

The Moose Jaw Air Crash: On April 8, 1954, a Harvard RCAF trainer and a Trans-Canada North Star collided over the city of Moose Jaw, killing 36 passengers and 1 woman on the ground. The largest fragment of the airliner narrowly missed an elementary school. Bodies and debris littered the city's fair grounds and golf course. In the days following, there were charges and counter charges surrounding the RCAF's contention that the air above the city was theirs and the TCA's claim that the RCAF's aircraft routinely buzzed commercial flights. While the inquiry reached no solid conclusion, commercial flights above Moose Jaw were rerouted and the city's air space was deemed off limits to passenger
