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.
