We all remember that magic day last September, when we all climbed onto our work roofs or stepped out onto the street and our porches to see the space shuttle make piggy-backed laps on a NASA 747 around the city. Well, most of us, anyway. We Instagrammed. We Tweeted. We even Facebooked as we ooh’ed and ahh’ed, with some even tracking the red-eye voyage from LAX to its home at the California Science Center.
