You speak as if the American "FAA" [Federal Aviation Administration, Washington, DC, USA] has some sort of legal control or jurisdiction over Thai registered airplanes operating in Thai airspace.
You speak as if the kingdom of Thailand were not a sovereign nation and that its Department of Civil Aviation, and "One-Two-Go" airlines in particular, were subject to United States operating standards. . . ?
How should the American FAA have "informed the public" in Thailand? . . . By placing ads in Thai newspapers warning Thai domestic travellers that its Thai airlines, its Thai licenced crews and its Thai registered airplanes do not meet American FAA standards....?
Obviously, you're a man with a mission regarding Thai aviation. But get real.
