If my memory serves me right, the airport commission seriously underestimated the number of passengers using Gatwick now and in the future. Didn't they forecast it would be another 10 years before Gatwick would get to the passenger levels it is now at. Their figures were wrong at the time the report was published, was it not?
Considering how important this is to the overall argument, why was the commission not asked to go away, correct their figures and rerun the report? Or would that not have delivered the right answer? Is it a case of expand Heathrow regardless, now make the facts to stick to support our decision.
