Liberty Magazine sponsored a song contest in 1938 for an official song of the Army Air Corps. The winning composition was a tune written in 6/8 time by Robert Crawford. It officially premiered at the Cleveland Air Races in 1939. The original title was "What do you think of the Air Corps Now?", but it was later changed to "The Air Force Song" when the separate U.S. Air Force was created in 1947.

The Air Force Song

Off we go into the wild blue younder,
climbing high into the sun,
here they come, zooming to meet our thunder;
at 'em boys, give 'er the gun!
Down we dive, spouting our flame from under,
off with one Hell-of-a roar!
We live in fame or go down in flame,
(shout)Nothing will stop the U.S. Air Force!

Minds of men fashioned a crate of thunder,
Sent it high into the blue;
Hands of men blasted the world asunder,
How they lived God only knew!
Souls of men dreaming of skies to conquer
Gave us wing, ever to soar.
With scouts before and bombers galore,
Nothing can stop the US Air Force!

Here's a toast to the host of those who
love the vastness of the sky,
To a friend we send this message
of his brother men who fly.
We drink to those who gave their all of old
Then down we roar to score the rainbow's
pot of gold.
A toast to the host of men we boast
The US Air Force!

Off we go into the wild sky yonder
Keep the wing level and true
If you'd live to be a gray haired wonder
Keep the nose out of the blue
Flying men, guarding our nation's borders
We'll be there followed by more
In echelon, we carry on
Nothing can stop the US Air Force!
