'Let's go!' Elizaveta Gushchina screamed before falling 290ft from the top of an abandoned boiler tower near the Russian city of St Petersburg.
'Liza', an extreme sports fanatic celebrating her 45th birthday with her son, dived down to the base of the boiler, shouting with elation as she cut through the air.
The jump would tragically be her last. The mother-of-two climbed back up to the top of the tower without safety ropes to mark the moment with a selfie.
But in an instant, after posing for a photo before the blue skies over Petersburg, the experienced jumper slipped and fell to her death in front of her son.
23block, which operates the popular facility for daredevils, confirmed Ms Gushchina, an established member of their sports team, had tragically lost her life.
