After the last shuttle launch, I heard that the shuttle would be visible overhead at a certain time. I went outside to check it out. Looking... looking... then straight overhead, head tilted way back, I thought I saw it... slowly moving farther behind me. I thought I'd turn around so I didn't fall flat on my back. Now where the heck did that go? Then suddenly, here comes the shuttle. Unmistakable. It was very bright and really moving along. It almost looked like an airplane cruising along - with no noise. I figured I hallucinated the "moving star." I think the power of suggestion comes into play in such an instance.
