The object moved at right angles.

I was looking out my window at night. I was looking southwest (in the direction of WPAFB). I saw a brite light that moved slowly in vertical and horizontal directions. It would move vertically, then stop and remain stationary for a few moments, then move horizontally, and stop, and it repeated that cycle a number of times. Then, in an instant, it disappeared by accelerating extremely quickly. It must have taken it less than .1-.2 of a second to disappear. A few points I'd like to make. First, when it was moving slowly and turning at what appeared bo be exact right angles, and starting and stopping, it did not appear to accelerate. This is what initially caught my eye. In other words, it moved without accelerating; it moved at a precise and steady speed and motion. Second, when it finally did 'take off' into the sky and disappear, it DID seem to accelerate, but at a phenomenal rate. Years later I was teaching in Taiwan. We had a discussion in class about UFOs. I asked my students if any of them had ever seen one. After a period of silence, one young man shared his story of having seen a UFO in Taiwan, I believe it was in the early or mid 80's. As he described what he had seen, I got goose bumps. He described exactly what I had seen in Ohio years ago. His description included elements such as turning at right angles, moving and stopping, then taking off ... it was uncanny. He was describing exactly what I had seen. Thank you.
