Sorry, but my jet airplane recognition is very poor. I know there have been previous posts from previous years on this, so someone can merge them if they want. Saturday 2010 May 15 around noon while talking to my neighbour, 2 jets roared overhead on their way to land at CYYC on runway 34. Now bear with me, they looked like F-18 or the fighterjet Canada has. Both were landing together. Later, while taking pictures at a baseball game near the airport, and again on the flight path for runway 34, I noticed another jet airplane banking from the east to line up for runway 34. Took some pictures that aren't very good as I mostly shot the undercarrage. However, under the cockpit was the British Air Force circle. Not sure if it was just refueling or staying here for a while if they have exercises at Suffield. One amateur radio operating has been very busy building "black boxes" for the British Army for exercises at Suffield. Thus, there may be some interesting monitoring or fighter jet plane watching over the next couple of weeks.
