The reach of gravity is infinite, so there is no place where you suddenly become free of Earth's pull, but there are points where it would be cancelled out by the pull of other objects, notably the Moon. There are places around the Earth and the Moon called Langrange Points, where this happens, and the closest is, i think, 5/6 of the way between the centres of Earth and the Moon, which is 314000 kilometres above the surface of the Earth. No plane could ever fly this high as a plane. A balloon would no longer be buoyant at that height, but balloons have actually been sent into orbit, for example Echo I, the first communications satellite.
Aside from these points, there would also be the Lagrange points between the Earth and Venus, which would probably be from about 20 million kilometres up, and similar points with Mars and asteroids which approach the Earth. These points can be used in general as a way of travelling around the Solar System.

Skydiving From The Edge Of The World.
On August 16, 1960, Joseph Kittinger jumped his last ... all » Excelsior jump, doing so from an air-thin height of 102,800 feet (31,334 meters). From that nearly 20 miles altitude, his tumble toward terra firma took some 4 minutes and 36 seconds. Exceeding the speed of sound during the fall, Kittinger used a small stabilizing chute before a larger, main parachute opened in the denser atmosphere. He safely touched down in barren New Mexico desert, 13 minutes 45 seconds after he vaulted into the void.
The jump set records that still stand today, among them, the highest parachute jump, the longest freefall, and the fastest speed ever attained by a human through the atmosphere. Somewhat in contention is Kittinger's use of the small parachute for stabilization during his record-setting fall. Roger Eugene Andreyev, a Russian, is touted as holding the world's free fall record of 80,325 feet (24,483 meters), made on November 1, 1962.
Michel Fournier is trying a higher jump, 40Km or 25 miles but as at today still hasn't achieved it.

The balloon would stop rising before this would happen. Even at the edge of space (approx 100km) gravity is still effectively 1g so you would still fall. In fact you would need to be about 25% of the way to the moon to stop this happening.
This is a common mistake. Items in earth orbit are not in zero-gravity but are in "free fall" which looks like 0g, feels like 0g but isn't.
I believe that the worst highest free fall parachute jump was made from a balloon at close to 80km but you need to check that.
Hope that helps

it isnt possible, unless the plane is flying faster than orbital speed, at which point it would be upside down and you would fall away from the earth. I wouldnt fancy your chances because you would be going about 40000mph. That will play havoc with the cut of your jumpsuit!

there's an excellent type of cynicism in this internet site. people can no longer fly using fact we aren't designed (anatomically) for it. we've not got wings and hollow bones like birds do. we gained't leap somewhat severe using fact we've too plenty density. perhaps people ought to fly and leap somewhat severe, if we had somewhat frail bodies, low muscle tissues, hollow bones and small brains. could you easily need to provide up extensive wakeful concept just to be waiting to fly or leap somewhat severe? i would not.

Not possible. The thing is to put things in orbit around the Earth.

Nowhere in the atmosphere...so from a plane/ballon the answer is they can't/wont

You couldn't breathe up that high. I would say around 7 kilometres. 4.5 miles.
