Wow, today was a big day in history.

In reverse order:

• 1976 – The first Space Shuttle, Enterprise, is unveiled by NASA.

• 1920 – The National Football League is organized in Canton, Ohio, United States.

And God bless ‘em for it, go Pack.

• 1862 – American Civil War: the Battle of Antietam, the bloodiest day in American history.

• 1814 – Francis Scott Key finishes his poem The Star-Spangled Banner.

Which is distinctly related to this next one:

• 1787 – The United States Constitution is signed in Philadelphia, Pennsylvania.

Happy birthday, Constitution!

One more, appropriately enough:

• 480 BC – The Battle of Thermopylae, fought between 300 Spartans, led by their king, Leonidas, and the Achaemenid Empire begins.*

Spoon!

* Note: there seems to be some debate as to the exact dates of the Battle of Thermopylae, but I like the connectivity of having it begin on the same day that the Constitution was signed.
