During a training run on the Olympic luge course, Indian luger Shiva Keshavan fell off his sled before making an amazing save, somehow flipping over and regaining his position on his sled. The scene made for a pretty mind-bending GIF, which makes it look like Keshavan was aided by CGI or wire effects.
You can see video of the crash and recovery on the NBC Olympics website, which offers this fun bonus fact about Keshavan:
Keshavan, who hails from India but will be racing under the Olympic flag because of his home country's suspension by the IOC, has already achieved a measure of viral fame due to his use of a Himalayan highway as a training track.
Looks like that bootleg training track prepared him well.
