Passenger aircraft don’t fly with full tanks, only enough to get to their destination + 45 minutes.
How would the pilot explain the need for more fuel? Once the payload is determined by the weight of the passengers and freight, the fuel amount is determined by the ground crew fuelers. Excess fuel would only increase the payload for no reason.
No, the pilot was stuck with the fuel onboard, it was always an iffy mission to India.
Why not hijack the plane in India, or Bangladesh, or Pakistan, or Afghanistan, or Sri Lanka? All countries with plenty of jet airliners and millions of disaffected people with experience in terrorism.
Why hijack the plane in Malaysia a country half an ocean away?
People really need to engage their logic in this case, they are letting their imaginations run wild over what I suspect will eventually turn out to be a run-of-the-mill plane crash.
Does anyone know if there is any crowd-sourcing of satellite image searches of ocean photos going on? It would seem if the right software was implemented to spread the effort evenly and prevent repetition, this might be useful, given the number of people online willing to check 10-50 photos for any sort of debris field.
