Flight MH370: The unanswered questions

The Malaysian prime minister has declared that Malaysia Airlines Flight MH370 "ended in the southern Indian Ocean", but several questions and enigmas surrounding the tragedy remain unsolved while the world waits for explanations.

Q. Why did Malaysia announce the aircraft had crashed into the southern Indian Ocean based simply on analysis of satellite data, rather than solid evidence such as authenticated debris?

A. Many people contacted by China Daily or discussing the announcement on the Internet have expressed concerns about whether the conclusion is justifiable and is based on enough evidence, given that no physical part of the aircraft has yet been retrieved.
