Typo at 7:34 : as I say, at launch, the four boosters of Soyuz are at 100%, the central one is at 70%. Speech is correct, text isn't.
This video tries to decipher some of the things we see when we watch a rocket launch, more precisely when looking at the flames coming out of the rocket nozzle during the first seconds of the flight. The second episode will focus on the rest of the flight.
