Supersonic flight "doomed"
Sceptics say plans to use aircraft that fly faster than the speed of sound to slash journey times are "doomed".
Environmental objections will severely limit the routes the futuristic planes can fly, making them uneconomic to develop and operate.
Former activists who campaigned against Concorde say any attempts to run a supersonic service would provoke the same level of protests that dogged the earlier jet.
