HC Deb 31 March 1971 vol 814 c386W
149. Mr. Crouch

asked the Secretary of State for the Environment to what extent he has taken account of the decision to proceed with further studies for the construction of a Channel Tunnel, and of the fact that such a tunnel should be in operation by 1978, in his consideration of the decision on the size and siting of the third London airport and also on the timing of the need for the airport.

Mr. Graham Page

The possible effects of a Channel Tunnel on air travel were examined by the Roskill Commission; they are being taken into account in the Government's study of the third London airport.
