I do. I completely agree with the hon. Lady; she makes a good point. The environmental improvements that we are seeing in aircraft, such as the use of sustainable fuels and vertical take-off aircraft, all need to be taken into account in the modernisation. I am told by various organisations that they have not been, or that after the airport gets the latest instructions from the Civil Aviation Authority, something else is improved and, by the time they go back with the proposals, the goalposts have shifted again. It is vital that the latest technology and improvements are part of the modernisation and that we do not find that when it comes into place it is already out of date.
