Malaysia is under fire for its handling of a missing airliner.  

Analysts voiced concern today over information gaps and contradictions during the massive search effort.  

But Malaysian transportation officials say they're satisfied with the level of cooperation surrounding the unprecedented search.

"This is a multinational operation. We are thankful for the cooperation of our friends and neighbors which is unwavering and quite overwhelming and we welcome even more expert assistance," an official said at a press conference. 

As you know, Malaysian Airlines Flight 370 vanished from radar on Saturday while en route from Kuala Lumpur to Beijing with 239 people aboard, including several Americans.

Malaysian officials say the U.S. stepped in quickly to aid in the search for the flight.

An international effort has been unable to uncover any clues about the flight's fate.
