There’s always a lot of finger-pointing going on, so it really isn’t unexpected that Ethiopia accused Lebanon of misleading and hampering the investigation. We should remember that the ICAO could not be there if the investigation did not live up to the highest standard.
It is also important to remember that any speculative conclusions, or “leaks” or preliminary investigation results are just that: speculation or investigation, or preliminary. It takes months and sometimes years to get to the cause of a crash, and this one is no exception. Eventually, no stone will be unturned.
Remember that all of the parties involved will be conducting their own investigations–not only the governments, but also the plane manufacturers, the component manufacturers, (any party who thinks they may be sued), as well as attorneys who are looking out for the welfare of their clients.
Many research teams are engaged in ferreting out, determining and studying the facts of the crash.
It is a shame that after all their grief, the families have to endure finger-pointing and speculative theories masquerading as truth, smokescreens which are put out by reporters or politicians for political purposes.
These investigations take time. There are no fast and easy answers. Look at the Air France Flight 447 crash of 2009. We’re still hearing all sorts of theories, but even in that earlier crash, the investigation is still going on; we’re still looking for wreckage and black boxes.
And so, the families weather the storm, continuing to bide their time, enduring their grief, and waiting—patiently or not—for facts, for answers, for the truth to show itself.
