Malaysia delays
Two points:
(i) It is a frustrating thought that the Malaysians knew the plane was missing while it was still in the air and potentially still discoverable and interceptable! With the benefit of hindsight, if only they had not waited several hours before making the inevitable announcement, it might have made a huge difference to the progress of the search.
(ii) Regarding the Inmarsat satellite that was pinged by the missing aircraft. Would the pings continue to be sent if the aircraft had landed safely? And if so, can we infer from the presumed absence of such pings that the aircraft did not land safely?
