Heathrow has no conscience. The CAA is pretty toothless for example helicopters are suppose not to fly below 500 feet but this is never monitored and it has no powers to monitor noise levels at the London City Airport. If the third runway is built at Heathrow there will be 50% more flights over this area. The London City Airport is being expanded and there will be more takeoffs when completed. Those residents who have dismissed this petition should perhaps think again or do they intend moving in the next few years? I don?t think I should have to move to accommodate aircraft pollution instead Heathrow and the London City Airport should be moved to the Thames estuary.
