§ 33. Mr. John Hallasked the Secretary of State for Trade and Industry what calculations have been made of the effect on the environment of the operation of the Concorde aircraft, in addition to aircraft now in use or projected for future service, when it is in full service; and what is his latest estimate of the number of Concorde aircraft that can then be expected to be in use.
§ Mr. CorfieldI do not think it is profitable at this stage to speculate on the number of Concordes that will be sold. But all our studies indicate that even a very large number of Concordes would not have a harmful effect on the environment.
§ 81. Mr. John Hallasked the Secretary of State for Trade and Industry what is his estimate of the annual consumption of oil of a Concorde aircraft in normal operation.
§ Mr. Corfield65,000–75,000 tons of fuel, depending upon the routes and frequency of operation.
