I'm going to give one more plug regarding maglev
Popular Science did a really crappy, IMO, rendition of a trans-atlantic maglev system, but that's another story. However, if a single maglev artery were to link JFK
, trans-Atlantic jet travel would be reduced into JFK
feeders, while a few P2P would be served with smaller aircraft. A sample itenerary might be-
onboard trans-Atlantic maglev
Later the same maglev track could be stretched to LHR
-OHR untill an arterial system of maglev links North America to Europe. At the same time, an artery through the Bering Straits could link North America to Asia. Air travel would become secondary to maglev, with the purpose of feeding these rail heads. The obvious site for rail-air integration would be beneath or within current airports.
All my humble opinion ofcourse.
