The hijack angle is making more sense with every passing day that the airliner goes missing.
Not at all, actually the opposite, the longer it goes unfound the more likely it crashed into the ocean. The ocean eats things. We’ve watched things crash into the ocean and had a hard time finding the actual wreckage. Break something up in deep water with strong currents and lots of stuff growing and it’s just basically gone, maybe centuries from now some very deep sea diver might find some pieces while on vacation. That’s generally how things get recovered.
