That report says 3.5 million people live within 60 minutes. True but the vast majority of those millions are well served by airports either side of Teesside that have bigger immediate catchment populations. Teesside's immediate catchment population is much less than a million which is exactly why the airport will not work. You cannot ignore the airports that serve Newcastle and West Yorkshire. Other than plonking another 1 million people in Darlington / Middlesbrough the writing is on the wall.
