Will a 3rd runway get built by 2011 ? Doubtful.
If you lived in Sipson and were told that you had to leave the home in which you'd lived for the last 20 years and uproot your family away from your friends for the sake of making others richer, wouldn't you feel aggrieved by it ? Or those who get increased noise pollution ?
Some may want a 3rd runway built immediately, but we would not be a civilised society if we did not give those who see an injustice the right to be heard and challenge any decision. If that means a legal challenge to the highest level, so be it.
