So according to that daft logic, we should remove Heathrow central area and flatten it, and knock down all the hotels along the north runway? And car parks? And then 'do' every other airport? And what would all that cost? The fact is aeroplanes are supposed to take off from runways and land back on them, not charge across local scrubland. If you think the world is going to pay for having surrounding areas flattened, you are more of an optimist than I am! Can we have some sensible suggestions now please?
