I find using infopig.com to be useful on picking up tidbits of news. When you pull up the site down below the flags is a list of countries. I chose Malaysia for this. reuters.com and then up at the top there is a choice box for what country. I like UK for international news but there is lots of other ways too.
The turn around was apparently on civilian radar until the transponder and tracking devices shut down. The primary radar for the region is the Malaysian military. Apparently they tracked MH370 to the Straits of Malacca on the west side of Malaysia.
I see there is a bit of doubt cast on this report but it is being checked out.
At any rate if it went to Malacca that is a busy area lots of people on ships and on shore to eyewitness a jet off the normal course. The beaches are accessible and soon debris of aircraft would be showing up if it crashed.
