Well, I said I was no expert on military aircraft. I know Canada does have other F type fighter jets [? F16], as I have seen them landing/takeoff at CYYC before. And the one landing had only one tail. smason, you should have stayed until 1630 as I heard a fighter jet take off about that time on runway 16 and then saw one about a minute later. As I live directly south of 16/34 if the winds are from a northerly or southerly direction, a lot of airplanes fly right over my house. Unfortunatetly, I have a lot of trees, so my field of view is very limited. However, I heard what I thought was another fighter jet take off about 1630 [second one] while I was outside and saw it banking from due south to east over McKenzie area. However, too far away to see much other than it was "moving" and was "loaded". Unfortunately, I wasn't monitoring any of the usual airport frequencies nor military-air frequencies. I don't usually monitor military-air frequencies as generally quiet in Calgary area. Darn those trees, but sure like to have them for shade on a warm day like today.
