“Investigators believed that the fuselage, with Vulović pinned inside, landed at an angle in a heavily wooded and snow-covered mountainside, which cushioned the impact”

Again incredible that she survived but she was inside some piece of plane which sounds like it both protected her and slowed her fall.

Wikipedia summarizes what I was getting at:

“Over the years, other skydivers have survived accidents where the press has reported that no parachute was open, yet they were actually being slowed by a small area of tangled parachute. They might still be very lucky to survive, but an impact at 130 km/h (80 mph) is much less severe than the 190 km/h (120 mph) that might occur in normal freefall”
