§ Mr. Adleyasked the Secretary of State for Trade and Industry whether he will publish a White Paper setting out the 15W scientific data relating to smoke emission and noise caused by supersonic flight.
§ Mr. CorfieldThe available evidence does not suggest that smoke emission is at all likely to present environmental problems since Concorde's engines will in service emit considerably less smoke than many existing subsonic types. As to the noise, I have nothing to add to what I have already told the House on previous occasions.
