Malaysian plane mystery is like trying to solve a crime without a body, witness, motive

Solving the mystery of the missing Malaysian plane is proving to be as easy as cracking a homicide without a body.

Or a witness.

Or a motive.

Eleven days after Flight 370 took a sudden, and still unexplained, left turn over the waters between Malaysia and Vietnam, a sense of bewilderment and frustration has settled in among not just the family members of the 239 passengers and crew, but also within the worldwide aviation community.

Basic questions remain unanswered.

Why was the plane commandeered, as investigators from Malaysia and other nations aiding the search have concluded?

What happened to the passengers?

And, fundamentally, where is the plane?

Meanwhile, foreign governments including the United States offer Malaysia help, hoping the small Southeast Asian nation accepts. The results have been decidedly mixed.
