In my mind this was quite quite deliberate. This was engineered by Egyptians in the control tower and maybe even higher up. It probably had 3 purposes: 1.to provoke Israel into reacting by maybe shooting down the plane. 2.To deliberately cause a crash 3.Maybe someone was on board who wanted to film something in ISrael or maybe the plane had been covertly fitted with a spy camera by Egyptian maintenance workers working at the airport who are sympathetic to Iran and the Muslim cause. Either way, Israel must act immediately with a very strict warning to the British aircraft carrier organisation that this will NOT be tolerated. Same goes for Egypt.
