Not an explanation about why your meteorite made no sound, but an interesting discussion about meteorites that do make a sound. http://science.nasa.gov/science-news...01/ast26nov_1/ in 1719 astronomer Edmund Halley collected accounts of a widely-observed fireball over England. Many witnesses, wrote Halley, "[heard] it hiss as it went along, as if it had been very near at hand." Yet his own research proved the meteor was at least "60 English miles" high. Sound takes about five minutes to travel such a distance,
