Although there has been much criticism of Malaysia's planning and coordination of the SAR, the planning is only as good as its execution and this Reuter's note suggests that whatever the Satellite images are, it was the Vietnamese who searched that grid reference. That is not surprising given it is within its territorial waters.
PHU QUOC ISLAND: Vietnam has already searched the area where Chinese satellites showed objects that could be debris from the missing Malaysia Airlines (MAS) flight MH370 but a plane has been sent to check the area again, Vietnamese military officials said.
“We are aware and we sent planes to cover that area over the past three days," Deputy Transport Minister Pham Quy Tieu told Reuters. “Today a (military) plane will search the area again,” he said.
Another military official said Vietnam was waiting to see photographs taken by a Chinese satellite on Sunday in waters northeast of Kuala Lumpur and south of Vietnam in order to identify the exact location for further inspection. – Reuters
