HOOSTEN......Argue all you want and make excuses.....THE SYSTEM FAILED MISERABLY AND 4 PEOPLE ARE DEAD......
This should have been preventable, they weren’t doing 400 kts either and the system should have advised them in plenty of time to take appropriate action to avoid each other.
Remember we had 3 very experienced Pilots ( no offense to the Thai trainee ) in those two Aircraft operating in a known environment with probably excess capacity available and they were still let down.....
Now stop making excuses.....
