TORY conference delegates were given a rude awakening yesterday by anti-Heathrow expansion campaigners who blasted loud aircraft noises through their hotel room windows.

At 4.30am — to coincide with the time flights begin taking off at Heathrow airport — conference delegates in Manchester were subjected to noise from a sound system hidden in a wheelie bin.

Campaign group Plane Stupid said the Midland Hotel action was in protest against plans for a third runway, which would be a “huge step in the wrong direction.”

Neil Keveren, who lives near the airport, played the noise to demonstrate the daily reality of 725,000 people who live under flight paths.Around 250,000 extra flights are expected to take off from the third runway.

Plane Stupid also unfurled a large banner on Manchester Central Library yesterday, opposite the hotel, which read: “No ifs, no buts — no new runways” as promised by David Cameron in his 2010 manifesto.

Heathrow resident Sandra Davis said: “We want to send a clear message to Tory MPs, staying just over the road, that giving the green light to a third runway will be met with fierce resistance to save the future of our homes, communities and environment.

“The air my family are breathing is already over the legal pollution limit with two runways.”

And another Heathrow resident, Emily Beeson, claimed that children living and studying in schools under the flight path can be as much as six months behind in school due to the deafening sounds from aircraft.

Plane Stupid spokesperson Sheila Menon said: “There is already more than enough aviation capacity.”

“Last year more than half the UK population did not fly at all, but the long-term negative impacts of airport expansion will mean everybody pays the price,” she added.
