I am almost too ashamed to admit it, but I have to agree with Zac Goldsmith on something; a third runway at Heathrow would be a very expensive mistake. (Cameron would pay a high price for a Heathrow U-turn, 08/09/12) More sensible routing of planes and more use of other airports would free up money for more essential infrastructure expenditure. If more money must be spent, yet again, on London,why not improve the public transport access for the disabled,as the brilliant Sophie Christiansen suggests? (London is horrendous, says triple gold medallist, 08/09/12) Why is it necessary, all of a sudden, for extra planes to be required for businessmen to go about their work? Video conferencing and emails have surely diminished the need for business travel, and further technological developments will undoubtedly reduce it further.Fancy a Tory MP suggesting the government has "been seduced by vested interests". Whatever next?
