Launch failuresEdit

Shijian 11-04 launch failureEdit

On August 18, 2011, a Long March 2C rocket failed during the launch of the Shijian 11-04 satellite. During the powered flight phase of the second stage, the connecting mechanism between vernier engine no.3 and the servo-control mechanism of the second stage failed, which led to loss of attitude control on the second stage.[3]
