Building Bigger Bridges?
This is a deeply mysterious report. Since most people get to airports by public transport and in London that means rail (by modern, not Victorian infrastructures).
Of course building a London to New York railway would be a tad expensive with the wrong sort of jelly fish causing some delay. The shipping alternative is not noted for its green credentials so efficient airliners maybe with some better thought out bio fuels is the best option for intercontinental travel. Instead of 'green' airline taxes that merely deny the poor, but benefit the rich, I always thought that deep and heavy taxes should only be applied to seating over 34". Highly efficient travel (bit of pain which restricts it to really valued travel) for those willing to squeeze in. And, hopefully, an end to the outrageously unenvironmental 'flying beds'. Or at least soak them to finance some decent green research.
@ FRank Bough - our new railway line opens in 12 months to relieve the growing pressure on the old. Being the East London (Overgound) Line it isn't going to displace any runways methinks ... just make London City Airport more accessible.
