The debate over a third runway for Heathrow has raged for a decade. But now there are controversial plans for a fourth. One of two different proposals were today presented to the Government's commission looking into airport expansion in the south.
A controversial proposal to build a fourth runway at Heathrow Airport is causing concern and anger in the Thames Valley. It is being put forward by a former Concorde pilot from Buckinghamshire and is now being considered by the Government.
Our Transport Correspondent Mike Pearse spoke to former Concorde pilot John Lowe, John Lenton from Windsor and Maidenhead Council and John Stewart, who is a Heathrow Campaigner.
The one presented today would extend the two existing runways towards the M25. It could mean parts of the M25 being put in a tunnel to create two extra runways. The rival scheme would see two runways built towards Windsor with claims up to 600 homes in the Horton area may have to be demolished.
Other options include new runways at Gatwick, Stansted and the so-called Boris Island scheme for a new airport in the Thames Estuary. The move would extend the airport closer to Windsor and increase flight numbers by up to half a million a year.
The man behind the latest plan - a former Concorde pilot from Marlow - spoke exclusively to our Transport Correspondent Mike Pearse.
