Pro ski jumper Daniel-Andre Tande suffered serious injuries in a terrifying crash caught on video Thursday ... but thankfully, officials are now describing his ailments as non-life-threatening.
Tande, a 27-year-old who won a gold medal at the 2018 Winter Olympics, was competing in a World Cup event in Slovenia ... when one of his jumps went horrifically wrong.
You can see in video of the crash ... midway through his flight, he turned sideways and landed HARD on the snow below.
The Norwegian then violently plummeted hundreds of feet down the mountain .
