Two white lights in the daytime skyI was outside of the building I work in and heard a helicoptor flying nearby. When I looked up to see where it was I noticed what I first thought to be a airliner flying at high altitude from east to west. When it stopped and appeared to be falling i realised it was not an airliner but a dot of light instead. It seamed to be falling for about ten to fifteen seconds when it suddenly moved back to the west very fast. That is when I noticed a second dot of light that the first had moved to and stopped. Both dots of light were stationary at that point and did not appear to be changing altitude. I called my co-workers to come and look but the dots seemed to slowly gain altitude and fade away before they were able to spot them. I was a clear day with scattered light clouds and excellent visibility at the time. It should also be noted that I am a former air defense crew member and have had extensive aircraft recognition training.
