§ Mr. Croninasked the Minister of Aviation what investigations he is now making into fog dispersal on airport runways.
§ Mr. ThorneycroftNone. As I explained in reply to the hon. Member for Gillingham (Mr. Burden) on 28th March, 1961, it was then decided that no useful purpose would be served in attempting to install F.I.D.O. at Heathrow. I am sending the hon. Member a copy of that Answer.
