Satellite-like object alters speed and does 90 degree turns as it crossed the skyKoblevo is a beaachj resort on the Black Sea coast of southern Ukraine. I worked as a Peace Corps volunteer in nearby Nikolayev (Mykolayiv), and a Ukrainian friend of mine and I went to the beach for a weekend. At approximately one AM, as we sat on the beach with a third individual, we saw what we believed to be a satellite moving from southeast to northwest in the sky. In the dark skies away from Ukrainian cities, satellites can easily be seen tracking across the sky. This appeared similar in color and in speed as it crossed the sky, until it began doing 90 degree zig zags and altering its speed several times, occasionally coming to a near stop. It had to have been very high or very far away, but it was obviously very fast and very mysterious. This incident was witnessed by me and two Ukrainian friends/acquaintances.((NUFORC Note: Date is approximate. PD))
