This incident will make some changes of aviation security measures. For example, some companies have already changed the rule that they will never let a pilot alone in the cockpit.
I want authorities to reveal the disaster in detail and make efficient now security measures to prevent the same incident.
Airline accidents make a huge loss at one time. But airplanes are still one of the safest transportatio system. Driving a car is more dangerous than a flight. To keep the air traffic security, many people have been working hard on the industry. I have to thank their effort and hope to keep the safety operations.
