Does anyone have doubts about the Malaysian flight MH370 having crashed into the Indian Ocean, as opposed to "some other scenario"?

What is everyone's opinions on this issue? What does it say about the technology we use in aviation? Do you think that the Malaysian Government Officials are withholding information that we could use to help find this airplane?

I believe that there is WAY more to this story than what we the people, and what our (the U.S.) Government is being told.
