===Heathrow expansion===
On 10 January 1946 the British Cabinet agreed Stage 3 of the airport, which was an extension north of the Bath Road, with a large triangle of 3 runways, obliterating Sipson and most of [[Harlington, London|Harlington]], and diverting the Bath Road.<ref>Sherwood 2009, p87</ref>

In 2009 the majority of the village was under threat of demolition owing to the planned [[expansion of London Heathrow Airport]], which would have created a third runway at the airport.<ref name="20090115announcement">{{cite web|url=http://www.dft.gov.uk/press/speechesstatements/statements/infrastructure|title=Transport Secretary's statement to the House of Commons, 15th January 2009|publisher=Department of Transport|access-date=2009-01-16|url-status=dead|archive-url=https://web.archive.org/web/20090306050807/http://www.dft.gov.uk/press/speechesstatements/statements/infrastructure|archive-date=6 March 2009}}</ref><ref name="BBC 7830275">{{cite news | url=http://news.bbc.co.uk/2/hi/uk_news/england/london/7830275.stm | title=New runway will demolish village | date=2009-01-15 | access-date=2009-01-15  | work=BBC News}}</ref> However, in March 2010 in accordance with multilateral environmental regulations and evidence that gas pollutant thresholds would be further breached within the wider area the English [[High Court of Justice]] ruled that the plan which the Department had submitted must be reconsidered.<ref>{{cite news| url=https://www.theguardian.com/environment/2010/mar/26/heathrow-third-runway-travel-and-transport | location=London | work=The Guardian | first1=Owen | last1=Bowcott | title=Heathrow protesters win third runway court victory | date=2010-03-26}}</ref> Accordingly, the Government announced in May 2010 that the third runway plan had been cancelled but that a long-term study into airport capacity in the South East and beyond may recommend expansion to any of the London Airports where the environmental constraints can all be met.<ref name="BBC 8678282">{{cite news| url=http://news.bbc.co.uk/1/hi/england/london/8678282.stm | work=BBC News | title=Heathrow runway plans cancelled | date=2010-05-12}}</ref> Since 2009 BAA have been acquiring property in Sipson and elsewhere when advertised for sale which means there will be fewer resident owners to oppose further plans for expansion with a third runway.  Contrary to this movement, opponents such as actress [[Emma Thompson]] and various others have bought land{{Citation needed|date=November 2019}} within the boundaries in 2009 with a view to preventing such [[expansion of London Heathrow Airport|expansion]]. In addition to this there has been a long term occupation of land within Sipson by climate activists on the invitation{{Citation needed|date=November 2019}} of local residents, following the latest Climate Camp. [[Grow Heathrow]] is a squatted community, opposed to the expansion of Heathrow airport and committed to finding sustainable alternatives in the face of climate change, peak oil and economic crises{{Editorializing|date=November 2019}}. 
On 2020-02-27 A court ruled the expansion unlawful in a case brought by environmental groups, councils and the Mayor of London. The court said the government would not appeal against the judgement.<ref>{{cite news| url=https://www.bbc.co.uk/news/business-51658693 | location=London | work=The BBC | title=Climate campaigners win Heathrow expansion case | date=2020-02-27}}</ref>
