=== Launch failure ===
The committee investigating the failed launch on July 26, 2006, concluded that the failure was caused by a malfunctioning of the pumping hydraulic drive of combustion chamber #4. The control malfunctioning brought about the disturbances, which led to the roll instability, excessive dispersions of the yaw and pitch angles. Thrust termination occurred at 74 seconds after lift-off. The crash site was located 150&nbsp;km from the launch pad in an unpopulated area of Kazakhstan. Toxic propellants polluted the crash site, forcing Russia to pay US$1.1m in compensation.<ref>{{cite web|url=http://www.iht.com/articles/ap/2006/11/03/news/AS_GEN_Kazakhstan_Russia_Space.php|title=Russia to pay Kazakhstan over US$1 million in compensation for damage from rocket crash|publisher=[[International Herald Tribune]]|date=2006-10-03}}</ref> The rocket used for this launch was more than twenty years old.
