But surely, if it flies in a straight line rather than following the curvature of the earth ... :laugh:
Curve? What curve? The Earth is flat - ask DD!

You don't see the words 'flat' and 'DD' in the same sentence very often.

What baffles me is that you can locate something as small as a mobile phone anywhere on the Earth using GPS and you don't have the technology to locate an aircraft. I thought the Black Box must have a GPS transmitter that can relay the aircraft's location to the nearest satellite or ATC.
Nope. Black boxes have radio transmitters, but they are well buried in the plane superstructure to give them the best chance of survival and probably couldn't get a GPS signal. Heck, it's bad enough getting a good GPS contact when you are in a tunnel, never mind under the ocean! :laugh:

Not exactly 'Global' then is it? Should rename it. :laugh:

Just read a comment on The Times website regarding this and it says. "
Quote:
Nigel Brodrick-Barker 52 minutes ago @Peter Jordan Is it remotely possible, Peter, that a lightweight aircraft, built of composite materials and flying at great altitude, could exit the gravitational pull of the Earth? Might this lost plane actually be in orbit?
Can anyone explain to me why this is guff?

This is mutually exclusive. An object in orbit is in orbit because it is under the influence of gravity - without that, it would be flying off in a straight line. Also, an airplane with engines that breathe air (which is most of them, but not all) can never achieve orbit (not under their own power anyway). In order to achieve orbit, you need to raise your periapsis above the atmosphere, which can only do from above that altitude, which means you can't be using an air-breathing engine to do it. Achieving escape velocity with an airplane is possible if you cheat, just strap rockets to an airplane, and make it happen outside the atmosphere. Doesn't really count, in my opinion. With an actual airplane, inside the atmosphere, under its own power - not going to happen. For one, you'd need a blunt heat shield just to avoid disintegrating. Also, you couldn't have wings. And I'm not sure even a scramjet will still work at that speed (some predictions give it a maximum speed of Mach 24 - not enough).

A story just broke on Fox News. Evidently the pilot 'floored it' and the plane is currently in space. Wow, aren't you embarrassed?

99.99% of people have no clue about how a rocket _really_ works, and think it is a kind of bigger robuster airplane, with extra tanks.

I think words like 'destiny' are a way of trying to find order where none exists. - Christian Graus Entropy isn't what is used to.
