Plane collides with ball of light

Was woken up by a noise like a plane.  Looked out my window, which I slept by in the summer to see a dot of line moving across the sky.  Movement was slow at times, then it would speed up and move in a different dirrection.  I remember becoming very scared and not knowing what was going on.  I then saw what appeared to be a plane, had all the proper flashing lights on it, and I could hear the roar of the engines, heading toward this other ball of light.  As the two got closer, the light became brighter.  Eventually the two seemingly ran into each other, there was a bright flash, all white.  And the dot of light just kept on moving across the sky.  I had checked the papers but there were no reports of a downed plane or a crash.
Date is approximate.  PD
