I wonder how much has been spent on LHR R3 planning, appealing, lawyers fees, public inquiries, impact assessments etc in the last 30 years? I've lost count of the number of times it has been given the go-ahead, challenged, appealed, shelved....then repeat those 4 stages over and over again with every election and change of government
Meanwhile many other countries just get on with it, ie France / Spain / Italy / Germany / China for high-speed rail and China for new airports.
Getting anything done in this country seriously beggars belief at times
