...Based on the 160-second burn and understanding that the first-stage boosters usually operate around two minutes in flight, this live firing appears to be normal. Roskosmos touts a "powerful" video tomorrow.

There are eyewitness accounts of a major engine firing at the Peresvet test facility near Moscow, which I guess, could be a long-awaited qualification of the Soyuz-5 rocket's first stage with RD-171MV engine, marking a major milestone in its development: russianspaceweb.com/soyuz5-lv.html
