Is that reasonable?
No, because if there is a problem at the start of the flight why would taking it into the air and finding it at the end of the flight be any safer? The whole issue of loading problems started when they took away the head count requirement to help OTP. Now they have bought the headcount back. OTP is someone elses performance indicator, its definitely not mine.
Don't forget J* used to have a culture of not reporting - the YMML TOGA-Tap incident from about 4-5 years ago was one of a string not reported until much later than the rules require.
How wrong do you want to be in one statement? The incident was reported at the time it occurred. It was the subsequent discovery of the GPWS warning off FOQA that wasn't passed on and neither was there a requirement to provide additional information. The incident is now 8 years ago as it occurred in 2007. What were the other incidents that went unreported? If they went unreported how do you know they occurred?
