Comparing apples and oranges with your analogy.
Actually travel by air is far safer than automobile transportation.
For these pilots to be "perplexed" means that there are serious unanswered questions...so terrorist/criminal causes cannot be ruled out until a full report is done.
Just trying to put things into a perspective you might understand since you clearly are not familiar the commercial aviation environment. Maybe it would help if you considered the recent accident in Toronto. Pilots were "perplexed" about the sequence of events there too. Nothing earth shattering about that, and it certainly doesn't imply there was anything sinister involved in that accident. The simple fact is, there are always "serious unanswered questions" at the start of an accident investigation. This latest mishap in Greece is no different. Therefore.....as we both agree, it is better not to draw any conclusions until a full report is done.
