And like others say- She was the only person of all those passengers plus crew that survived that ordeal.
We will never know if others perhaps also survived their fall, because not all the passengers and crew were found back. But she's clearly the only one that walked out of there and lived to tell.
That in itself is near to impossible- but it happened.

January 26, 1972, 22-year-old flight attendant Vesna Vulovic, was on a DC-9 which got blown up by a terrorist group. She was in the tail section of the plane, which fell 30,000+ feet, crashed onto a tree-covered, snow-covered mountainside, she was the only survivor. Severely injured, but she recovered.

//"you've won nothing" - you mean there's prizes?

"Pure conjecture. There are no facts to support it. Most people are notoriously bad at estimating height - especially when their plane breaks apart and they lose consciousness."

She never states she fell 2 miles down. The article states the following:

"Then Koepcke lost consciousness again. She fell more than three kilometers (two miles) into the jungle canopy but miraculously survived with only minor injuries. Ninety-one other people aboard Flight 508 died."

Why do people like you exist? What is the point you are trying to make? You're making a point with incorrect fact... congratulation, you've won NOTHING.

The reason why I remember it so vividly is because there were scenes where she had an infection from some insect bites, and she had to squeeze the worms out of the bites.
