in 1968, after an inconclusive public inquiry, the Government appointed Hon. Mr Justice Roskill to head the Commission on the Third London Airport (the "Roskill Commission") to review sites for a third airport. Cublington in the Vale of Aylesbury was its chosen site. It was seen offering the best access, as it was situated on the key London-Birmingham axis, it would be away from built-up areas and it would cost less than most of the alternatives. The proposal met with strong opposition from local people and more broadly from politicians and middle-class voters which made it politically untenable.
