Prospective Volume of 16-Mm Films
Major increases in the volume of 16-mm release prints made from 16-mm originals can be confidently expected. The vicious circle of "no films, no projectors" has been broken by the training and other film activities of the Armed Forces in the United States and also in other parts of the world. During World War II, along with Lend-Lease deliveries of American-made P-39 Airacobra fighter planes to the Russians, sound films describing their servicing and maintenance were supplied. Although the earlier films were merely copies of the films delivered to the American Air Forces, later films used Russian sound tracks and other editing modifications to produce a Russian version.
Conservative estimates indicate roughly a fourfold increase in the number of 16-mm sound projectors in use in the United States as a result of World War II. The number of hours' use per year per projector has also risen markedly. Well over 500 million feet of 16-mm film was manufactured and used in a single year during the war interval. Although much film and many projectors are worn out or are obsolete and should be scrapped now that their war uses have been satisfied, the volume of such material remaining is still far larger than that of all films and all projectors in existence prior to the war. Efficient utilization of such material is desirable if the nation is to realize the maximum benefit from its large war investment.
Even though most efficient utilization of the surplus films and projectors may be made, large gaps will still remain in our civilian educational and training system. Production of a large number of subjects as parts of integrated teaching and training programs is still badly needed, as are improved projectors to show such new films. Technology was accelerated by the War to a greater extent than at any other time in our earlier history. An urgent need now exists to spread rapidly and widely the knowledge gained from this growth and to capitalize upon the technological advances made.

Single System vs. Double System Sound Recording
As in 35-mm, 16-mm sound film may be made by either the single system or double system method. In the single system method, the sound is usually recorded at the same time that the picture is taken and recorded photographically upon the sound track area of the same film
