The wire you see with the parachute on the end of it is a telephone wire, being payed out from a C-47 cargo plane.
Bell Telephone Laboratories, working with the Air Technical Service Command of the Army Air Forces, developed this idea. It will save precious lives and time on the battlefield.
A soldier throws out a parachute with the wire and weight attached. The weight drops the line to the target area. From then on, through a tube thrust out of "the doorway of the plane, the wire thrums out steadily sixteen miles of it can be laid in 6-2/3 minutes. Isolated patrols can be linked quickly with headquarters. Jungles and mountain ranges no longer need be obstacles to communication.
This is in sharp contrast to the old, dangerous way. The laying of wire through swamps and over mountains often meant the transporting of coils on the backs of men crawling through jungle vegetation, and in the line of sniper fire. It is reported that in one sector of the Asiatic theater alone, 41 men were killed or wounded in a single wire-laying mission.
Bell Telephone Laboratories is handling more than 1200 development projects for the Army and the Navy. When the war is over, the Laboratories goes back to its regular job helping the Bell System bring you the finest telephone 'service in the world.
