The case for a third runway at Heathrow will be submitted today by bosses of the west London airport. The three options which will be presented include:
1) A third runway to the north west of airport which would require part of the M25 being put in a tunnel and affect the villages of Longford and Harmondsworth.
Passenger capacity: 130m. Cost: £17bn. Starts: 2026. Demolishes: 950 homes
2) A third runway to the south west of the airport which starts over Wraysbury and King George VI reservoirs. A section of the M25 would need to be reconfigured and tunnelled and the village of Stanwell Moor flattened.
Passenger capacity: 130m. Cost: £18bn. Starts: 2029. Demolishes: 850 homes
3) A third runway close to Sipson, Harlington and Cranford Cross. It would be a shorter length with fewer planes, the cheapest and quickest option but also the noisiest and the highest number of homes would be affected.
Passenger capacity: 123m. Cost: £14bn. Starts: 2025. Demolishes: 2,700 homes
