Millions of dollars of additional investment have been ploughed into airport security since the 11 September terror attacks.Security officials at airports have little tolerance for passengers joking about "bombs" in their luggage and airlines can refuse to take such travellers on board. 'Tis a matter of grinning and bearing the theatre.
Paul Zanetti
