A tragedy in the sky was reported just recently. An airplane owned by a small Swiss company crashed into a mountain yesterday, leading to fatality of all of passengers and crews. The victims counted twenty.

This airplane was 79-year-old. I am not sure if such an old aircraft is utilized for usual flight. According to the company, there might be no troubles regarding the maintenance of the plane.

On the other hand, it is a little odd that this plane did not carry a black box. The lack of flight recorder will make it difficult to discover the cause of this accident.

Anyway, pray for the victims. I hope similar tragedies will never happen.
