anyone have info if they have searched northern part of the arc south of Indonesia?
Not sure, but what I do believe is that the US military have the airborne drone technology to conduct arial drone searches quickly. Thus they could have been checking out near all of the suspect areas for surface debris fairly promptly. With a Global Hawk RQ-4A or RQ-4A BAMS drone. They have high resolution cameras, approx. 1 metre resolution capable. They can search 40,000 square miles ( 200 x 200 miles ) in 24 hours.
