To set the record straight, I'm well acquainted with one of the crew involved. The item was discovered several hours into the flight in one of the many catering bins onboard a 747. It was more than a toothbrush. It was a large wrapped package all alone in a bin. Dimensions approximately 8 inches by 8 inches by 17 inches. It fitted all descriptions of a 'suspicious' object that should not have been there. It's a good idea for amateurs not to tamper with items like this. Consultation took place with head office and it was agreed with the operating Captain that a precautionary landing take place without undue delay. NO emergency was declared, the passengers were informed that a precautionary landing was to take place (and why), and after landing an orderly evacuation took place on three sets of steps, followed by transport immediately to the terminal. The Indian Airport Authorities were superb and the military team inspecting the item quickly established that it was a large box of used Qantas Club washbags, presumably dumped in a bin for shipment from Singapore back to Sydney. Crew hours problems necessitated nightstop. Big problems getting hotel rooms for all as a major conference was underway. Not much drama. Flight continued as soon as an alternative crew were available.
