Heathrow Expansion London Airports Virgin Hyperloop One
Instead of expansion at Heathrow, redefine the London Airports strategy as an integrated mesh service joined together with Virgin Hyperloop One. The travel time between Heathrow and Gatwick is less than 10 minutes. That is less time than terminal to gate in most instances. In the other direction add Luton and Stansted. Connections air side only to provide security and prevent massive overloading which would be detrimental to the speedy and easy joining of all of the airports runway capacity. Greener than another runway at heathrow, and then another, and probably cheaper. BAA may have to be resuscitated to make a single London strategy work. Consider adding Southend and Rochester Airports to make it a full loop, running in both directions. Perhaps not Rochester but somewhere in Kent.
Very little traction with this idea.
