As an intrested and sympathetic ATC person, I wonder if we are not getting sidelined whether pilots should or should not be armed, and whether the flight deck door is locked or not.
The important thing is to make all efforts with the regulatory and airport authorities to make sure that these hijackers do not get on the aeroplane in the first place by the use of increased security, surely if these hijackers are on board the aeroplane then the battle is effectively lost.
