I've read articles that reckon these 'MagLev' trains will hit 4000kph.
Until some kid works out how to cross polarise the tracks!
How about we take an A380 type aeroplane - fill the bottom deck with enough fuel tanks, multiple crew rest stations, food, and **** cans to fly it non-stop from Sydney - London or Sydney-New York? What does that sucker cruise at 500 kts? I figure that's about 18 hrs to London!
I wouldn't want to be cleaning said '**** cans' after that flight!
