Needs to be going pretty fast for that to happen at lower altitudes to overcome gravitational pull (centripetal effect). Higher up there are a couple of "sweet spots" where lunar and terrestrial gravity cancel each other out. Beyond those you'd probably be captured by Lunar gravitational force and head that way. There's a formula for those who wear coke bottle glasses involving mass and distance which would probably give you a better idea.
There's no clear boundary between Earth's atmosphere and space, says Dr Kevin Pimbblet, lecturer in astrophysics at the University of Queensland.
"As we go up and up and up and up, through the atmosphere, it just becomes less and less dense," he says.
Luckily, we humans like drawing boundaries so you can choose between several that claim to mark the 'edge of space'.
The most commonly accepted boundary of space, says Pimbblet, as defined by the World Air Sports Federation (Fédération Aéronautique Internationale), is something called the 'Kármán line', 100 kilometres above Earth's mean sea level.
"This line is where the atmosphere becomes too thin for aeronautical flight to happen," he says.
After this boundary, you'd have to travel very fast horizontally (faster than the speed at which the Earth orbits the sun) to gain altitude vertically, something that isn't possible in your average aircraft.
If you're too busy looking out the window and miss this boundary, there's another at 118 kilometres above the Earth just above the Kármán line. This boundary, measured and drawn up just recently by a group of Canadian and US scientists, marks the spot where ions charged particles created by solar radiation begin to take over the atmosphere in earnest.
Ions beyond this boundary can travel up to something like 1000 kilometres per hour or thereabouts, says Plimbblet.
The test demonstrated that not only did the capsule system function exactly as planned but the giant stratospheric balloon did as well, as balloon expert Ed Coca confirmed. The delicate giant, which was inflated overnight before the start with 14,000 cubic meters of helium, was remotely deflated exactly as planned at an altitude of just under 30 kilometers. The space capsule that Baumgartner had been riding in was detached with an explosive device from the balloon descended under a parachute and later landed undamaged in the desert.
