Story on the back:

"Under orders from the White House, a squadron of jet planes was sent up to try and locate the enemy saucers which had attacked a U. S. military base. For the first hour there wasn't any sign of a spaceship. Just as the pilots headed back to their base, radar revealed four saucers soaring toward the jets at fantastic speeds. The U. S. planes fired at them, but the ammunition bounced harmlessly off the metallic exteriors of the saucers. Returning the fire, the alien ships sent two jets crashing to the Earth in flames. One of the pilots tried to get a look at the inside of a spaceship. Seeing this, the saucer smashed itself in the jet without any damage to itself."
