The Space Shuttle Discovery just made its last flight ever atop a 747, where it'll be laid to rest at the Smithsonian for the public to appreciate. We won't see something like this again for a long, long time.
Not bad for a little taxpayer bread and circus action, right?

CNN confirms the duo arrived safely at Virginia's Dulles Airport, concluding the most exciting 15 minutes in Washingtonian history.
Meanwhile, NASA captured the whole thing with none-other than Instagram.
