Of course, because if you have the fantastic knowledge of avionics required for all this to have been done by a hijacker, you would have no idea about the fuel capacity of a B777.
I mean if one wants to attack a target in India using a hijacked jet the obvious place to hijack the jet would be over the Gulf of Thailand in a jet flying from Malaysia to China. Because as we all know there are no jet aircraft anywhere near India.
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.
