A) Off-loaded and probably dealt with as infidels by Muzzies worldwide.
B) Do you know how many islands there are in Indonesia and the Philippines and that region of the world? Think of the leftover, abandon WWII airfields that could be covertly repaired.
C) I haven’t seen “Non-Stop.”
It seems overly elaborate to me. The Iranians would have had to buy an old airfield (probably the whole island) and upgrade it for the size of the aircraft. They’d also have to have the pilots be in on it. Hijacking aircraft these days is a difficult task without some signal getting out, even if you get a gun on board.
