About ten seconds before the sonic boom occurred at EAFB, I heard a very loud 'crash' in Ventura California, about 100 miles due west. Challenger was travelling relatively slowly, but still 'hopped' 100 miles almost instaneously. It was very exciting to have it fly overhead and to see it land only five minutes later 100 miles away. (The sonic boom was a quick double pulse boom.)
