Deset, Devyat, Vosem, Sem... That countdown in Russki brings back memories of interesting weapons test tapes during the Cold War. I'm sure my Russki opposite numbers found some of our tests just as interesting.
This attempted launch though was of a civilian satellite, from Sea Launch using a Russian Zenit booster. From the looks of it, they had successful main engine start, then a loss of thrust just as the clamps were let go. The results, as can be seen, were spectacular, and Sea Launch's one and only launch pad is going to look distinctly second-hand. Of course, in the Rocket Biz, it's not a "failure", anything at all unexpected, from a transient sensor glitch to an Earth-Shattering Kaboom is an "anomaly".
Here's an example:
Having many tons of burning solid fuel raining down in lumps like that is not conducive to the good health of anyone outside a bunker.
Another view showing the size of the explosion, taken from further away, is available here. More Fun with Rocket Failures below - including a static structural test showing that the assembly wasn't quite strong enough.
