This was a proposal to extend the current runways westward. It was being proposed by a consortium that is independent of Heathrow Airport Ltd and is not currently being supported by them as an alternative to their own proposal. A couple of members of the Residents Association committee have met with a couple of their representatives who gave a short presentation about their proposal. This presentation can be viewed here. They also produced a brochure with a similar set of messages and that is available HERE.
