Where did the flight attendant fall from?

Adéla Babanová and her brother Džian Baban, a screenwriter and musician, are exhibiting a fictitious interview with the flight attendant Vesna Vulović, who in 1972 was the sole survivor when an aeroplane exploded over Česká Kamenice. She is the only person in the world to have survived a fall from such a height.
