Sonic boom

There was a sonic boom yesterday when the space shuttle landed in California. There was actually 2 of them in a row. It pretty much shook the whole house and I'm sure everyone in our neighborhood felt it and heard it. When i went to my mom to ask her if she knew what it was she said it no and looked all surprised and thought that we dropped something upstairs and i told her no that it was a sonic boom because i knew, my dad had told me ahead of time. She said really?, in a surprised tone and i said yeah. My friend came over a little after and i asked him if he knew and he said yeah that it was a sonic boom so yeah it was pretty cool. It was a pretty cool experience.
