Space Shuttle Sonic Boom

Waah! I was just talking to my Ge Ge (well C and I have decided to become pinky sworn siblings, so he calls me Mei Mei and I call him Ge Ge) anyhoo, we were discussing legal stuff, and then we were startled by a huge, loud boom! At first we thought the building shook, then we looked out to see maybe it was thunder, but it does not rain in SoCal in the summer... it turned out the Space Shuttle just landed in Edwards Air Force Base, and it was the sonic boom, wahhhh... the govt should've told us... how are we to know what it is? Sniff sniff... life is sooo hard and somebody loves to whiiiinnnee....
