Build an air tight Tube that goes from Point A to Point B. Inside this tube resides a railed transport. The transport is held to the tube via super slippery rails. A gap of whatever is necessary is provided between the Transport and the Tube.
Transport has Jet engine going through it. Jet engine thrust
backwards, all air not going into jet engine flows around the vehicle via the gap.
Passengers ride in the Transport, and the transport is built around this Jet engine. The Jet engine is built to rotate, allowing for the vehicle to tilt slightly for corners, directing any G forces downward relative to the Passengers 'down'.

You don't want to know what happens when something goes... wrong. |

Thing is, if you just create a vacuum in front of the shuttle you wouldn't need the jet. [link] |

I remember reading something
somewhere in my youth, ages ago, that
scientists somewhere had theorised that
if a tunnel were to be built between any
two points on earth, and a friction-free
rail carriage were to be pushed to the
other end, in a vacuum, the gravity
would pull the carriage down, and back
up again, with the additional 'push' at
the start, to make it to the other end.
They reckoned that it would take
something like 39 minutes*. From any
point to any other point on the planet. |

*I've probably remembered that number
wrong - all numbers are pretty much
the same. |
