Gatwick already has half the capacity of Heathrow with only one runway, its the busiest single runway airport in the world, so its equally busy. It needs better public transport (i.e. Zone7 on a Travelcard, & frequency). It can build a new runway at less expense to the taxpayer & while we’ve bailed out the banks can we afford to bail out HAL? The worst environmental conditions at LHR are already well known, especially to locals!
