§ 10. Sir Leonard Lyleasked the Secretary of State for Air whether any aerodromes and, if so, how many, have been constructed for less than 25 per cent. increase over the original estimate?
§ Sir A. SinclairIn a very large number of cases the original estimates of cost had to be increased owing to a subsequent decision to provide hard runways and later to extend the runways to meet operational requirements. Where, however, construction has proceeded on the basis of the original requirement, some 80 per cent. of the aerodromes have been completed at a cost less than the original estimate plus 25 per cent.
