Hopefully: * War * Garbage * Pollution * Taking your shoes off in airports :)

  > * Taking your shoes off in airports :) As someone who is not at all fond of flying, hopefully they'll judge the whole idea of tin cans hurtling through the sky, powered by highly flammable chemicals as being a bit primitive.

    Looking at current research I would think that in the future plastic cans will hurtle across the sky, powered by more flammable but biodegradable chemicals. ;) I think airplanes are here to stay for some time. There are few alternatives, one of them high speed rail, which has its own problems.

        I was actually thinking about the absurdly high cost of high speed tracks (tens of millions per kilometer). But yeah, oceans are somewhat of a problem.

    Airplanes are far safer, per mile, than buses or trains (about 10x less likely to die), never mind cars (60x). Edit: corrected numbers.

  Taking your shoes off in airports :) This comic comes to mind every single time I go through airport security with my laptop. http://xkcd.com/651/ http://xkcd.com/651/
