With the crash of another Malaysia Airlines Boeing 777, this one in eastern Ukraine, aviation accident investigators are again asking the same big questions as in any disaster: What happened and why did it happen? In the case of the disappearance of MH370 this spring, the answer at this point on both counts is that no one knows. This will not be the case with MH17. We already know a lot about what happened — if not why.
To start with the obvious, we already know where the airplane is. Searchers, many of them local residents, began finding wreckage the bodies of the victims almost immediately after the crash.
