    Hypersonic plane to fly at 20 times speed of sound

    The US military aims to fly a hypersonic plane at 20 times the speed of sound by 2016.

    The X-plane will travel at Mach 20 (roughly 20,900 km/h), which means it could fly to any place on earth in less than an hour.

    They've been talking about stuff like this for a LONG time.

    The economics just aren't there. It's half-plane/half rocket. Which makes it hideously expensive, and only worthy for rather niche applications.

    On the bright side, much will come from research into the materials required, hypersonic aerodynamics, and a few other branches of applied science.

    Soon it will take less time to travel across the country than it does to both get to the airport and get through security.

    this is the U.S. military we're talking about. the air force has spent ~$45 billion on B2 bombers alone. I bet they'll develop the thing and it'll be outrageously expensive and there won't be any practical use for it except to make the military look good.

    e.g. Space elevators. If they can get away from the amount of energy that needs to be burned to move out of the atmosphere, that would probably be a cheaper more viable option.

    Well, if they do accomplish this, time travel will happen simultaneously.

    I can confirm this. I remember a conversation with my brother's roommate, an aerospace engineer working for NASA, in 1988 about something like this. A half-plane/half-rocket vessel that would launch into the stratosphere and fly commercial passengers anywhere in the world in under an hour.

    Obviously that was 24 years ago and that scenario is no closer to reality today than it was then, and likely won't be reality in another 24 years.

    The concord couldn't stay around in the civilian realm so I assume that if this flavor of plane ever comes to pass it wont see the light outside of the military$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$

    These types of craft have literally one application in the current world - delivery of weapons..

    Still I'm excited to think they can achieve this - it will be amazing to see how it changes the world..

    Due to the impending energy crisis' of the next 40 years or so its likely we'll see a lot less travel - or it becoming horrendously expensive.
