§ Mr. Russellasked the Minister of Aviation if he will state the cost of operating escalators in the No. 1 Passenger Building in London Airport; and what would be the additional cost of operating a series of trav-o-lators on the horizontal corridor along which passengers have to walk to go to and from the building and to aircraft.
§ Mr. MartenThe annual cost, including charges on capital, of operating the existing escalators is about £1,200 a unit. The use of trav-o-lators in the airside gallery has been considered but rejected as not practicable.
