No one was injured. No one panicked. But you can see the moment the October 2018 spacecraft launch from Kazakhstan goes bad.
Everything seems to be going smoothly at first. But at about 0:48 seconds, with the camera focused on Russian cosmonaut Alexey Ovchinin and American astronaut Nick Hague (a colonel in the U.S. Air Force), something fails (later determined to be a rocket booster issue) and everything starts shaking.
Again, no one was injured. Watch the 1:25 video at the top of the page for the full series of events. And then you can watch the below video (direct from NASA) of Col. Hague talking about what happened.
