AEROPLANES IN FOG
A paper on “Landing Aircraft in Fog,” prepared by Flight-Lieutenant H. Cooch, -was read at a meeting of the Royal Aeronautical 'Society in London, reports the Weekly Scotsman. Describing the instruments perfected for use on machines, the writer said that on a one J two hundredth scale model it had been found possible to guide a machine, and eventually land it on the model aerodrome without the operator seeing either machine or ground. The instrument in its present form consisted, of three ground glass scales over which spots of light moved. •Scales one and two indicated whether it'lie machine was directly over, or to the left or right of the correct track, while scale three only operated when the machine was over the correct landing ground. The instruments used, declared the writer, were so sensitive that they recorded signals which were far weaker than those required to give an audible signal in a telephone.
