Couple of years ago when someone was arguing with my about high speed rail a Brit piped up with how much it'd cost to build third runway at Heathrow. Something like $12 to $15 billion. Which is what convinced me the California High Speed rail a good idea. Build that and you don't need to expand about 8-12 airports.
