Invented: a camera which will operate at an altitude of more than 30,000 feet, penetrating hazes and photographing in a single exposure an area of over four square miles, automatically timed and operated, electrically heated to prevent freezing, making an exposure nine by eighteen inches in size.

The inventors: the U. S. Air Service and the Fairchild Aerial Camera Corporation.

The purpose: to enable photographers in time of war to fly high above enemy territory and laugh at anti-aircraft guns popping uselessly beneath them.
