Security is very much bluster- all show and no knickers. Look at the various catering units around the world- off airport, staffed by low paid and very dodgy looking types. How easy to slip something into an empty catering bin going to a particular flight. It will be transported (with maximun security) and loaded on that flight. Will it be checked before departure- apparently not! It is not part of the Cabin Crew checks to inspect 'empty' bins! Who is to say those oven meals contain food and not something else just waiting to be cooked? We have recently had a diversion following discovery of a suspicious package in just such circumstances. Unless Security is sensible targeted so that resoources can be put elsewhere, it will just be what it has become- a self serving empire farce.
