"Plane Safety" [Run Time 2:36]

Beginning shots include boats on a rough sea, a wrecked ship in a storm, and a crashed plane. A narrator talks of navigators piloting their craft without any outside aid while at the mercy of the elements. A blind man is seen walking along a pavement with a cane, as the narrator says that radio direction-finding helps to find a way for unseeing eyes. An airplane takes off from Le Bourget for Amsterdam. On board, the navigator taps out signals by Morse code for a ground control station. The pilot flies into low-lying clouds and a co-pilot taps out a message to ask for a fix. Men in direction finding stations listen on radio sets and mark positions on large maps. Position fixes are radioed back to the planes. The concluding shots feature airplanes flying, superimposed over a spinning globe.
