Since the thread has diverged a bit into all questions and answers about aviation out of YYC I thought I'd put up some links that I use to get info on the interesting stuff flying out of our airport:
http://flightaware.com/live/airport/CYYC FlightAware page for YYC, good to catch "rare birds" coming through. Military flights don't show up though.
http://atm.navcanada.ca/atm/iwv/CYYC NavCanada wind information, also showing which runways are currently active.
http://twitter.com/WeeinYYC Tweeter WeeinYYC, works at Westjet and has some good connections to get the scoop on rare visitors. An amazing photographer also.
