    Hmm. What the page says is
    
    "Voir le lancement (Real Video - 1,7 Mo - 74 secondes) jusqu'à la spectaculaire séparation des boosters."
    
    which is,
    
    "See the launch  (Real Video - 1.7 MB - 74 seconds) up to the spectacular booster separation."
    
    OTOH my trusty " International Reference Guide to Space Launch Systems", 3rd Edition indicates
    that the first stage separation happens at 121 sec, with the second stage igniting about four seconds
    earlier (presumably exhausting through the lattice interstage structure).
    
    Between that and the apparent confusion between Plesetsk and Vladivostok in the next pictures,
    I'm going to do a bit more fact-checking.
    
    But the video was cool, nonetheless.
