SIN
RE: The route taken by the B777 could have been carefully planned to avoid Singapore airspace.
Agreed, the SAF will scramble very quickly and are happy to show their strength. But the same goes for India, China and a few others. Also bear in mind Singapore and it's airspace is relatively small.
However I am hopeful the investigators are close to coming to a conclusion. I will hope for the best but fear a long salvage operation.
