GUIYANG, Feb. 4 (Xinhua) -- A ceremony was held Sunday at a military base in southwest China's Guizhou Province to mourn the air force servicemen who lost their lives in a recent military plane crash.

The People's Liberation Army (PLA) air force plane crashed in Guizhou during a training session on Jan. 29. The staff aboard the plane died.

On Friday, they were honored as revolutionary martyrs by the air force of the Southern Theater Command.

The ceremony was attended by military leaders and members of the armed forces, local officials and relatives of the martyrs.

The servicemen who devoted their lives in the accident had previously completed missions in a number of military exercises and combat readiness training.

Ensuring flight safety is the common pursuit of air forces all over the world, the statement read.

The PLA air force will continue military training under combat conditions with tough and strict standards and enhance its capability to win wars, according to the statement.
