The annual commemorations of the crash have, over the decades, included events in the area near where the wreckage came down. The local memory of the event — the community’s relationship to what happened on that January afternoon — is a dimension of the story that sits alongside the individual narrative of Vulović’s survival. The place where the crash happened has its own relationship to the event, shaped by the generations of residents who have known about it and by the annual presence of those who come to remember.
## The Science of Falls: What Research Has Shown About Survival at Altitude
Vesna Vulović’s survival has drawn interest from researchers and physicians who study what happens to the human body in extreme circumstances. The scientific literature on falls from altitude provides a context for understanding how her survival was possible, even as it acknowledges that no complete explanation exists.
Falls from altitude have been documented in aviation accidents throughout the jet age. In each case where a person has survived a fall from significant height, investigators have identified some combination of factors that reduced the lethality of the descent: snow, trees, water, terrain slope, or structural debris that altered the dynamics of the final impact. No credible case exists of a human body falling freely from high altitude and surviving contact with a hard, ungiving surface.
The physics of terminal velocity establish a baseline: a human body in free fall reaches approximately 200 kilometers per hour (roughly 55 meters per second) in the spread-eagle position. At that velocity, impact with most surfaces is universally fatal. The deceleration from 200 km/h to zero over a very short distance produces forces on the body that exceed what biological tissue can sustain.
