So, as usual it seems, we’re now being told that the bill for Heathrow Runway Three is going to be much higher than is being said. Worse, that extra cost is going to fall on the taxpayer and not on the private enterprise (the airport). Yesterday’s Guardian reported former Transport Secretary as the person raising the concern:

“There will be a number of specific things we will be doing for Heathrow. The government and Heathrow need to come clean on what the cost to the taxpayer is going to be.” … While the [Davies] commission report estimated a £5bn bill for new roads and rail links, Transport for London put the potential cost as being as high as £18.4bn.
Heathrow said it had earmarked just £1bn, and that it only accepted direct responsibility for works to the M25, which the third runway would cross, and a few minor roads. The airport contends that it will be cutting traffic, despite adding up to 55 million passengers a year, and that revenues could offset the bill.

Oh? Pray tell me how adding 55 million passengers a year will reduce traffic.
Moreover:

Heathrow confirmed on Wednesday that executives would be paid bonuses, for securing a new runway, that would be expected to run into several million pounds.

And there’s even more …

Campaigners have highlighted an apparent admission that pollution is likely to rise in parts of London with a third runway, which they say potentially makes the scheme illegal.
The report, produced by Parsons Brinckerhoff for the DfT, said that Heathrow was “at risk of worsening exceedances of limit values alongside some roads within greater London, but this would be unlikely to affect the overall zone compliance”.
However, this is likely to be contested. Legal opinion obtained by the Clean Air in London campaign, from Robert McCracken QC, states that worsening pollution in any areas that already exceed legal limits would break the law.

That’s alright then, bugger the law. Oh we’ve already done that.
And don’t you just love “at risk of worsening exceedances of limit values”. WTF language do they think they’re writing? Can’t be Vogon; we’d stand a chance of understanding that.
So as usual it seems we’re not being told the whole story; there are hidden vested interests and conflicts of interest. And the whole funding situation is being fudged so that in years to come it will be too expensive (financially and politically) to scrap the project so it is completed with money we don’t have, provided by central government and filched from the pockets of the already screwed taxpayers — or worse borrowed on the never-never. (See HS2 and London’s proposed Garden Bridge for similar current likely examples.)
It’s another plane crash (in so many ways) waiting to happen. And government don’t get it. In spades. FFS!
PS. I know I live near Heathrow (though not under the main flightpaths) but I don’t care where this runway is going to be built. We shouldn’t be doing it. And we certainly shouldn’t be doing it — like most major projects — in such an underhand way.
