155. Mr. De la Bère
asked the Minister of Supply whether, in view of the fact that during the period of hostilities the Government were prevented from making any public pronouncement regarding the development of devices used by the Service Departments on the general progress and improvement in apparatus to counteract fog, he will now make a comprehensive statement on this matter and indicate the methods by which it is proposed to utilise the knowledge gained for the benefit of the public; and whether there is any additional progress to report as a result of research since the cessation of hostilities.
§ Mr. Leonard
The only practicable method developed during the war for dispersing fog on airfields was that known as F.I.D.O. Owing to its cost it is not likley to have much application in peace-time, and development work on the system has ceased, although installations are being retained at a few R.A.F. airfields, and we are keeping in close touch with experimental work proceeding in America. The regular landing of aircraft in fog is more likely to be achieved successfully by radio, radar and instrumental aids which are being actively developed.
