Bad news: The crazy Sukhoi Su-35 stunt was not entirely true. The pilot flew without canopy, but the ejection was on the ground. Dangerous, but not that dangerous. We tracked down the video, which shows how the eject seat works.
The clip is from Mirror Wars, an unwatchable Russian action flick about some plot to steal a secret plane to kill the President of the United States onboard Air Force One. Or something like that, who cares. Oh well, at least we don't have to watch a similar craptastic movie hoping to find the actual jump. [Thanks Dan]
