A glider is about to attempt a record-breaking flight to the edge of space  

In a place in South America, where powerful winds blow, scientists are preparing to launch an attempt to fly a glider and its human pilot all the way up to the edge of space.

That’s a height of 90,000 feet.

If the flight is successful, Perlan would break the world altitude record for a fixed-wing aircraft, and do so without using so much as a single drop of fuel.
