Speculation that Maplin might be looked at again as an airport – ruled out for very good reasons in 1974

By 19th July, all outline proposals airport plans need to be submitted to the Airports Commission (see below). There will be a great many, some more serious contenders than others. At this stage, the Commission does not require detailed design and assessment materials and limits submissions to 40 pages. Unsurprisingly, there is speculation that schemes like Maplin could be dug up and submitted. Maplin Sands was considered as a possible airport in the early 1970s, under Edward Heath. The plan was abandoned in June 1974, after the oil price rose and the it was decided that the Maplin Development Authority should not spend any more money. Maplin was mentioned, in passing, in a reply to a question in the Lords – which did not rule it out.  In reality, it is inaccessible and in the wrong place. It would be unworkable and hugely expensive, as well as the problem of needing to move the military firing range from Shoeburyness, and clearing the site of projectiles.  Not a likely runner.



Maplin Sands back on airport shortlist

Friday 14th June 2013  (Southend Echo)

A NEW airport at Maplin Sands, off the coast of Foulness – which prompted huge opposition in the Seventies – will be considered again.

Earl Attlee, Government transport spokesman, told the House of Lords a new airport at Maplin Sands will be looked at as part of an investigation into aviation capacity in the south-east. [What he meant is more likely to be that the Airports Commission will have to look at all plans submitted; he did not mean that they will look at a plan for Maplin with any great favour. AW]. 

A new Thames Estuary airport will also be considered as part of the inquiry by the Airports Commission.

The prospect of a new airport at Maplin Sands sparked a huge campaign in the Seventies and was shelved in 1974 in the wake of an oil crisis.

Lord Higgins,a Tory peer, asked Earl Attlee in the Lords debate: “Given the legislation for a hub at Maplin Sands went through with comparatively few problems back in the mid-Seventies, is there not a case for looking at that site again?”   [ Lords discussion in Hansard on Monday 10th June 2013 ].

Earl Attlee responded: “The Airports Commission will look at all sites, including Maplin Sands or the Thames Estuary airport, and will then come up with a shortlist of which options need to be looked at in greater detail.

Rochford district councillors have dismissed the latest investigation into Maplin Sands as a “complete waste of money”, claiming none of the problems of access or cost that stopped the plans in the Seventies had been solved.

Terry Cutmore, Tory leader of Rochford council, said: “Any proposal would be incredibly expensive.

“Because of where it is situated, if any proposal did come forward, there would have to be a great deal of investment in local transport infrastructure.

“Yes, you can get there, but Maplin Sands is not easily accessible like Southend or Stansted Airport–that does not make it particularly attractive to air passengers.”

“The site is also very close to testing facilities run by the MoD that would be very difficult to replace.

“The plans are unworkable and any investigation would be a total waste of money.”

Mr Cutmore said an airport would bring extra jobs and investment to the area, but this could be at a high cost.

He added: “Much of Rochford is very green and residents have a good quality of life.

“We want to preserve that as much as possible.”

The last government considered the plans again in 2002, but they were again abandoned for being unworkable.

Speaking in the Lords debate, Lord Attlee, said: “The long-term question of aviation capacity is a matter of national importance.

“It is vital the Airports Commission has sufficient time to carry out a thorough investigation of the options, and to build consensus around its long-term recommendations.

“The timetable set for its final report, by the summer of 2015, will allow this to take place, and will enable a stable, long-term solution to be found.”





Maplin (Foulness) – from Wikipedia


One influential member of the Roskill Commission, Colin Buchanan, dissented [against Cublington) on environmental and planning grounds and proposed an alternative site at Maplin Sands, Foulness, in the Thames Estuary. This opened the door to strong political opposition against Cublington and in April 1971 the government announced that the site at Maplin Sands had been selected for the third London airport, even though it was the most remote and overall the most expensive of the options considered, and that planning would begin immediately.

In due course the Maplin Development Act received Royal Assent in October 1973. In 1973 a Special Development Order was made under the Town and Country Planning Acts granting planning permission for the project, and the Maplin Development Authority was constituted and began its work. The project would have included not just a major airport, but a deep-water harbour suitable for the container ships then coming into use, a high-speed rail link together with the M12 and M13 motorways to London, and a new town for the accommodation of the thousands of workers who would be required. The new town would eventually cover 82 square miles, with a population of 600,000 people, while the surface route to the airport would require a corridor 100 yards wide and over 30 miles long. The cost would be a then-astronomical £825 million (£7,430 million today), which many – particularly in the Labour Party, which was in opposition at the time – regarded as unacceptable.

The Maplin airport project was abandoned in July 1974 when Labour came to power.  A reappraisal of passenger projections indicated that there would be capacity until 1990 at Heathrow, Gatwick, Stansted and Luton, aided by regional airports. The scheme was abandoned in favour of a cheaper plan to enlarge Stansted rather than building an entirely new airport; the requirement for a container ship harbour was to be discharged by the development of Felixstowe. The dilemma regarding the location of an additional airport, whether inland or on the coast, was summed up by an airport expert quoted by New Scientist magazine in 1973: “An inland site is not on politically, and a coastal site is not on economically.”





London’s Thames Estuary airport plans – déjà-vu all over again!

7.9.2012  (Royal Aeronautical Society, blog)


Airports in the Thames Estuary are nothing new, 40 years ago they were headline news.  A guest post from David Hurst MRAeS delves into the archives.


Tests had shown that an airport built on sand could cope with the weight of a VC-10. (RAeS/NAL photo).

Forty years ago the papers were full of stories about the need for the third London airport. Airport capacity is still news and the Thames Estuary is again being looked at as the solution.

Back in 1970 the stories largely resulted from the opinion of the late Sir Peter Masefield, a lifelong civil aviation businessman, who, depending on your point of view, was either a far-sighted visionary or had simply got his figures wrong. He showed that Heathrow and Gatwick would run out of capacity during the 1980s unless something was done. He was wrong then but maybe the crunch is happening now.

The worldwide civil aviation business has grown at an average 5 per cent a year since the 1950s and continues to do so. There are occasional recessions and wars which can delay the effects for a year or two but the trend is clear.

World air traffic growth

After 1945 the major airports were directly run by government departments. In 1966 four airports were grouped together to be run by a separate organisation, the British Airports Authority, under the chairmanship of Peter Masefield. The four airports were Heathrow, Gatwick and Stansted serving London, together with Prestwick in Scotland. Edinburgh, Glasgow and Aberdeen airports were added later. Southampton joined much later.

Masefield was convinced that the third London airport should be Stansted, then a small public airport with a large runway built for the US Air Force.

Continuous controversy resulted in the Roskill Commission which was to consider all possible sites. Roskill gave the government a choice of four: Cublington – not a million miles from the current HS2 track in Buckinghamshire; Nuthampstead, Herts; Thurleigh, Essex, and Foulness, later called Maplin for obvious reasons after sands slightly further south.

The Commission plumped for Cublington following a detailed cost/benefit analysis. There was a dissenting opinion by the transport planner Sir Colin Buchanan who favoured Maplin.


Backing Maplin

Edward Heath’s Conservative government decided to back the Maplin option. Detailed studies had quietly started in July 1971 and on September 28, 1972, the first meeting of the confidential Maplin Project Management Committee was held under the auspices of the Department of the Environment to co-ordinate the work.

A wide range of studies were commissioned but a major obstacle was seen as the moving the military firing range from Shoeburyness and clearing the site of projectiles. The Ministry of Defence were less than enthusiastic but eventually a civilian workforce of some 200 people were engaged on the clearance work. The likely location of the replacement range was Tain in Scotland. It was decided that it was only necessary to clear the sands only to a depth of 1.5 metres as tests on Concorde and VC10 aircraft had optimistically shown that, with concrete and the fill on top of the sand, the vibrations of landing were unlikely to disturb anything that had penetrated further down. The Boeing 747, just entering service, let alone the undreamed-of Airbus A380, were not mentioned.

The Maplin Development Authority, tasked with reclaiming the 30 square miles of land required for the new airport and sea port, held its first official meeting on November 6, 1973. The chairman, Sir Frank Marshall, said in his only annual report that the investigations had indicated that it was ‘an area exceptionally suitable for reclamation at a lower cost than was previously envisaged’. The Dutch were particularly helpful with their experience in such matters.

Once the land was reclaimed it was to be handed to the British Airports Authority to build the airport and to the Port of London Authority to build the accompanying sea port.

Norman Payne, then chief executive of the British Airports Authority, announced broad plans for the airport in March 1973. When it opened, it would have a single runway and one terminal but, by the late 1990s, the plan was for four runways, each of 4,250 metres, and ten terminals arranged as a spine between the runways.

Access would be by a non-stop rail service from Kings Cross, taking just 40 minutes There would be a motorway link from the planned London Ringway (subsequently abandoned but parts would become the M25) and both the road and the railway would enter the spine of the airport from the south and later continue from the north end of the site. The airport would handle 32 million passengers annually by 1986 and 120 million when completed in the late 90s. Cost estimates at the time produced figures of around £1,000m for the entire project, including urbanisation, by the 1990s.

Aircraft would approach and depart entirely over the sea. There would be 400 houses within the 35NNI noise contour as opposed to 250,000 at Heathrow.

The Port of London Authority had identified the potential of Maplin a decade earlier and had extended its area of responsibility to include the site. It had seen the need for a major deep-water container port and a terminal for super-tankers and were eager to start construction. The reclaiming of 30 square miles at Maplin was just part of its broad plans to reclaim some 300 square miles along the Thames estuary.

Problems arose in October 1973. As a result of the Arab-Israeli Yom Kippur war, the price of crude oil soared from $3 a barrel to $12 (or $60 at 2011 prices – today’s price is around $135 a barrel). By March 1974, petrol prices at the pump had risen 70 percent and the first fuel crisis was in full swing.

In February 1974 there was a general election which resulted in a hung parliament with Labour forming a minority government under Harold Wilson. Various reviews were undertaken and on May 8, 1974, the Department of the Environment wrote to the Maplin Development Authority instructing them not to incur further costs and to plan to shut down by 30 June. The Cabinet confirmed the cancellation at their meeting on 16 July 1974.

Curiously the sea port was not mentioned in the cancellation and even in 1976 the PLA was still hoping that it could be developed.


What if…?

If Maplin had gone ahead, what would have been the consequences? First, Stansted and Southend airports would have closed completely and would probably have been turned over for housing or industrial estates. Development of Luton airport would have been curtailed and much of its traffic would have moved elsewhere. Manston would probably have shut when the RAF moved out. Development at Heathrow would have stopped at three terminals and two runways and Gatwick would have remained with a single terminal and one runway. Their aircraft movements would be capped at 1980 levels. In 1980 Heathrow handled 294,619 aircraft movements (480,906 in 2011); Gatwick reached 143,522 (251,067 in 2011). West London and north Sussex would have been around 40 per cent quieter now.

With a major seaport at Maplin, Felixstowe docks would not have happened, and much port development on the Thames estuary may not have taken place. Plans for the estuary airports would not have even been considered.

One could surmise that London’s development towards the east would have happened sooner and, without the major airport development at Heathrow, there might have been less urban development in west London and along the M4 corridor as well as the Crawley/Burgess Hill area. East Anglia would have had much more development, especially in Essex. The airport alone would have eventually needed 60,000 staff by the 1990s. And the 2012 Olympics might be taking place in Wembley, not Stratford.

The significant question is whether the airlines would have used Maplin. Moving the infrastructure of a home base is hugely complex so UK airlines would have faced serious decisions. Overseas carriers rarely consider a particular route more than a season or two ahead so they are more flexible – note how quickly current low-cost airlines start-up and stop services. However, the large scheduled carriers prefer to work on the honeypot principle and swarm in one place even if facilities are better elsewhere.

Alternatively, airlines will always go where they think they can make money. If there is enough traffic, someone will operate an air service.

In the 1970s the government was enthusiastically interfering in business decisions. After the cancellation of Maplin it attempted to move all the Canadian and the Iberian air traffic, including British Airways, from Heathrow to Gatwick. That was only avoided by a general election. It did insist any new airline wanting to serve London should use Gatwick and not Heathrow, just at the time US airlines were expanding into Europe. Today, those airlines have disappeared or squeezed into Heathrow and there are now few major overseas scheduled carriers serving either Gatwick or Stansted.

The panic caused by the escalating oil price rise did not last. Air passenger figures for the London area peaked at 29.41 million in 1973, dropped by two million in 1974 and were back at 31.03 million in 1976. In 2011 the six London area airports handled a total of 133.71 million passengers; nearly fourteen million more than the planned capacity of the completed Maplin.

Airports Commission – 19th July deadline for submissions

Following the submission of expressions of intent in February, the next deadline for submissions will be 19 July 2013. By this date, we will need to receive outline proposals. These should give an overview of the level of additional capacity that would be provided, along with some of the key economic, social and environmental considerations. As stated above, we do not require detailed design and assessment materials at this stage; we are envisaging submissions of no longer than 40 pages. They may not need to include detailed designs for new runways and terminals, though in some cases those bringing proposals may wish to include them where they are fundamental to other areas of their analysis.
