I have not reported this before. I feel it should be recorderd somewhere. My friend and I used to take time-lapse photos of the stars and he was a member of the Civil Air Patrol. We were in the backyard and watching for meteors when we saw a "star" traveling from the north horizon to the zenith. It was approximatly the same brightness as Vega.

It was very high and traveling very fast. It was at a very high altitude or very small.
There was no sound. The most important part of the sighting was that when it reached straight up from us, (almost perpendicular), it made a 90 degree turn.It did not slow down, it did not describe an arc, it made a pinpoint turn like you would draw with a triangle on paper. Given what we knew at the time about aircraft and the "g" force that would be experienced inside an aircraft, it scared us back into the house. I have never been able to forget what we saw and I have yet to see any human technology that could do what we saw. I swear this is true and hope it might be of some interest to you. I can't write this in one sentence, sorry.
Date is approximate.  Witness elects to remain totally anonymous.  Please see other report from St. Louis, MO, for the same month.  PD
