This investigation has not being conducted according to ICAO 13 and we should ask the last 2 questions:
Who is serving this information to the media and what is the purpose of it?
ICAO 13 cannot override a state law.
BTW, in a modern democracy, can you imagine they would answer
nothing to say to the relatives when 149 persons have been killed ?
Professionals are working for their customers, the last ones are not travelling just to make the first ones enjoy their job ;-)
