With so much being touted about multi country search, defence secrets etc. leading to lack of coordination, why is it that so far corporates are not being included in any of the searches and public releases?
AW, as the home country of the airline involved, Malaysia is in charge of the investigation and information dissemination protocols and timing are entirely up to them. Under ICAO rules and other agreements, it would be inappropriate for Boeing or any other commercial or government entity to comment without the consent of the Malaysian government.
Note: Had there been a known crash site, the country where it occurred would be in charge.
