I am an electrician in Fort McMurray Alberta I was going out for a cigarette at exactly 907 pm ( iPhone was in hand) I always look up just to check out stars / northern lights etc. as I was staring almost straight up the object broke the edge of the roofline above my head and proceeded above cloud cover in a northerly direction. It made exactly five course corrections at speeds far beyond anything I am aware of ( live near Canadian AFB see a lot of fighters etc. ). Object was above light cloud cover and gave off a diffuse pale yellow light ( no smaller details visible . The object then vanished over perceived horizon provided by town house across the backyard ( sub division ) the object went in and out of sight in approx 1.5 seconds so quickly It was comparable to at least 20 times the speed of a commercial jet. As I have already timed a commercial flight at high altitude in relation to sighting and it was at least 23 seconds for the flight to come in and out of sight. Speed and handling that was quite frankly awe inspiring. I have seen many things in the sky and this was with out a doubt an object we have no direct knowledge of under intelligent command. unreal experience. Gave me butterflies and scared me half to death. I am privileged to have seen it. I have made a crude drawing of flight path etc and would be happy to forward.
