Don't get me wrong, I hate the airport. I hate the noise, the smell of aviation fumes, etc. But thinking that an island full of runways is a sufficient replacement is a joke. Infact the mere fact that aircraft take off from LHR is not even significant in my eyes, due to all the extra businesses surrounding the airport, that don't even care about flight.Or, perhaps we are too dependant on Heathrow as it is. Yes, even though I work there, I dislike it...
