The backers of the “Heathrow Hub” rival Heathrow expansion scheme are considering legal action against the Government in the wake of the airport’s move to propose potential revisions to its plans. Heathrow Hub, fronted by former Concorde pilot Jock Lowe, has criticised the Government for allowing Heathrow to now consult on new ideas for its 3rd runway because this could change the eventual scheme from what was originally submitted and considered by the Airports Commission. Heathrow’s consultation (started 17th Jan, ends 28th March) is considering 3 different runway options, two of them for a 3,200 metres and one at 3,500 metres, slightly differently sited. This is in spite of the Government’s own documents on the expansion stipulating the need for a runway of “at least 3,500 metres”. Heathrow has to try to keep costs down, as its airlines are bitterly opposed to the cost of its proposals. The consultation also outlined potential plans for how to deal with the runway crossing the M25 motorway. Heathrow Hub said if it did launch legal proceedings, it would aim to get the money it spent submitting its proposals for expansion to the Government refunded. Heathrow airport said it thought that “providing some flexibility on the specification of the precise runway length would not undermine the NPS and its objectives”.
