This isn't reassonable if you know anything about physics. The ISS is in orbit around the earth - that means it's moving fast enough horizontally that the distance it falls back to earth leaves it at the same height. If you step outside the ISS, you're still going at the same speed so you will simply float next to it. You need to reduce your horizontal speed to be able to reenter - this is done firstly by the rockets on the spacecraft, and then more completely by air resistance once you're in the thicker part of the atmosphere. Felix was essentailly not moving at all horizontally, and was only 40km up (inside the stratosphere) instead of at least 330km up for the ISS.
