lomapaseo says NTSB people are biased. I have read NTSB reports that are more outspoken against the industry norm & the FAA than any I've seen in the UK for example.
Look up their report on the Korean crash at Guam & see how they ram home the fact that they have written to the FAA, made recommendations about fatigue and over how many years. Look at the website & see how they display the status of Fatigue & other issues. They leave one in no doubt that they try everything within their power to get change and that they are unable to shift the FAA.
The CAA, FAA & too many regulators are in the grip of the industies commercial priorities and will not change unless something comes down from above - maybe this should be on Obama's hit list?
