Just found the web site of the Friends of the Earth on LHR T5 -a must read, there's also a chilling map by Hacan of possible crashes on Heathrow flight paths.
Stricken jumbo flew over West London (also there)
The AIB report is here (direct link to PDF).
The Government has proposed building a third runway at the airport, which would add 1,000 more flights a week over the capital. Most other big cities have positioned their airports in places that do not require planes to approach over the centre."
FOE comment. Heathrow is by far the most dangerous airport in the country for those on the ground. This is because there are far more planes flying over far more people than anywhere else. This fact is largely ignored by the government, which takes into account only 'individual risk' as opposed to 'societal risk'.
Update: Seems Friends of the Earth moved to a proper website but did not migrate all files, this link doesn't work anymore. Fortunately,
Waybackmachine had an archived copy... Here's another link to the document, just in case.
