Avid Cool Like Pie Reader "Big Greg" sent us these photos of the space shuttle landing in Washington, D.C.
He was driving around the city when suddenly the loud noise of this unusual mission stopped everybody in their tracks.
Crowds of people looked to the sky and snapped pictures with their phones.
"Big Greg" just so happened to be in front of the United States Capitol when he captured these cool shots.
The space shuttle is attached to the top of an airplane.
The shuttle will never fly to space again. Discovery will make it's final journey to the Smithsonian Museum today.
It will soon be on display for all of us to see.
