So far four aircraft, and and up to seven ships have failed to locate the debris detected in those satellite images, according to the Australia Government.
A statement from the Australian Maritime Safety Authority confirmed that the search operation has finished for today and will resume again on Friday. No sightings were reported.
Apparently weather conditions in the area are quite rough and it may take some time until something is recovered from the sea.
