I see. If the plane maintained an altitude of ~5000 feet and bearing that took it over sultan ismail petra airport and the small island the military radar picked it up in the strait it would have struck the mountains on the northern part of Aceh. Those mountains peak between 5000 and 9000 feet.
Or was the plane taken to central Africa?
Well this, if confirmed, is certainly another twist. According to the residents in Kudahuvadhoo the low-flying large airline they saw was traveling from the North, and headed South Easterly.
Roughly 0615 local time (so, lighting conditions match for a visual sighting). Interesting. But, that location is quite some distance from the last verified position of MH370. Curious.
