A good friend of mine used to be a baggage handler with a "major Australian airline"
About 5 yrs ago, he accidentally went to work for nearly a week with a Leatherman in his side pocket. He had inadvertly put his work pants on an hr before work and did a couple of house jobs and forgot to take the Leatherman out.
Of course, he turned up to work, day after day, got a very lazy wand passed over him and after about 5 shifts realised what he had been taking to work for nearly a week.
This whole security thing is load of bull$hit.
5 years ago there used to be a woman in Brisbane, she used to snatch your paperwork out of your hands just before you went through the metal detector. She would shake the $hit out of it to see if a Nuclear Weapon fell out or something?
