The sound was a brief & single suddle \"crash\" (similar to a thunder bolt). While I did not have a stopwatch handy, I estimate the crashing sound to occur about 20 seconds after the impact.

The impact occurred behind a hill. I didn\'t see the actual impact, but I did see a brief bright glow coming from behind the hill, followed by the sound of a suddle \"crash\" (similar to a thunder bolt).
