Yet more rubbish from Panorama. Last time they toid us WiFi was going to kill us now. Now it's impossible for a 450-seat twin engined aircraft.

A350-1000 - 412 passenger twin jet - near as damned 450.

David, London,

Boeing 777-300 (ER) - Twin engined with 2 Class config giving 451 passengers (is replacing a lot of 747-400s). It will be interesting to see what figures are produced and then compare them with this aircraft, but in any case it's fuel efficiency not number of engines or plane size that counts.

Russ, Reading, UK

BAA should be broken up to introduce some real competition in the industry, not pandered to.

Richard, Edinburgh,

Surely an invented aircraft is as much a lie as a ficticious arircraft?

Or am I missing something.

Could it be on similar lines as being 'economical' with the truth.

David Kinsley, Derby, UK

We should be decreasing air travel - environmental & fuel issues, and instead increasing national and intra-continental rail travel. We have a very long way to go before our rail system is as good or cheap to use as the rest of the EU.

Alistair, London,

Over 400 years ago it would have been *high treason* for any Englishman to conspire with the Spanish. Now-a-days the British Government itself conspires with Spanish owned BAA / Ferrovial to obliterate English villages - to build yet more duty free hypermarkets. That is far worse than high treason.

Chris J Brady, Harlington, UK

Does anyone seriously believe that if pollution or noise is too high then BAA will reduce flights in to and out of Heathrow? I dont think so! Once the cap is lifted to 700k flights a year then this data will also be fudged.

Everyone in London deserves to live in an suitably healthy environment.

Rich, London,

lies lies and more lies.
sipson villagers are the victims of economic bullies. Families suffering for profits of greed.

We are being governed by a bunch of liars and incompetents, but for how long are we going to let this carry on ?. They clearly dont give a damn about the public they are meant to serve and really this Govt's behaviour is disgusting.

alex, london, uk

So the data is fixed, and we have yet to even have a health assessment re pollution and noise impacts. At what point does government collusion become corporate manslaughter. This is not about 'living near the airport' this is about human rights to have kids without asthma - we fight we will win

Christian, London, UK

The British people must owe an apology to the Labour party for being such a terrible inconviennience. All this work it has to do, to hide the appauling effect their airport will have on millions of people's health & quality of life. We do get in the way don't we (apart from the crippling tax bit..)

grant, london,

Artifically reducing the Quad % is only one of the measures proposed by BAA / DfT to improve air quality around Heathrow.
Another is to reduce road traffic in the M4 / M25 corridor by using road tolls to force car drivers onto Crossrail; this will then allow for additional plane movements.

Peter Hooper, Windsor, UK

This news should come as no surprise. The Department for Transport has been the political wing of BAA, and the aviation industry in general, for many years. The only surprising point is that other government departments, notably DEFRA, have also succumbed to the aviation lobby.

Brian Ross, Bishops Stortford, UK

I remember the T5 Inquiry when BAA submitted flight growth projections - which suddenly suffered from "Brewer's Droop".
Then there were the results taken by BAA's mobile noise monitoring unit which were witheld from the T5 Inquiry on the grounds that the 747-400 aircraft were flying too low !
