How many runways for Heathrow ?

RE: How many runways for Heathrow ?
LHR was conceptualised during WW2 with the vision of the needs of the 70s. I reckon we need to do the same. Start again on a new site. Build something with enough runways and terminals, and large enough gates and public areas to handle the aircraft and passenger needs to sustain the capacity to enable it to be the best european hub throgh 2040 - and preferably owned by and generating revenue for the british taxpayer.
