Lightning struck the right wing. A fire broke out. The right wing separated from the aircraft, and part of the left wing separated as well. The structural failure was catastrophic and rapid. Flight recorder analysis placed the breakup at approximately 12:45 local time.
For those aboard the aircraft in those seconds, the experience was incomprehensible. Juliane Koepcke has described the moment of breakup as a transition that happened faster than understanding could follow: one moment the normal noise and sensation of flight, and then — in her BBC account from 2012 — “Suddenly, the noise stopped, and I was outside the plane.”
She was still strapped to her seat. In the sudden absence of the aircraft around her, she was falling through a thunderstorm, in her seat, in her graduation dress, over the Amazon.
## The Fall
What happened between the moment of breakup and the moment she regained consciousness on the forest floor the next morning is, by definition, mostly beyond documentation. She was unconscious for much of it. What is known is what she has described and what can be reasoned from the physical circumstances.
The fall was approximately three kilometers — roughly 10,000 feet, or just under two miles of vertical distance. This figure is a reported estimate, not an instrument-measured certainty, and the exact altitude of the breakup and the exact point of impact cannot be reconstructed with precision. What is clear is that she fell from a substantial altitude through a thunderstorm and landed in rainforest.
The question of how she survived the fall has been the subject of sustained speculation in the decades since, and the honest answer is that the specific combination of factors is not fully knowable. Several hypotheses have been proposed, and Juliane herself has articulated some of them:
