Air France plane grounded after bomb scare
Although this was a hoax, it still highlights the importance of having your staff trained in identifying and responding suitably to any kind of threat of this nature.
"The object, made up of cardboard, paper and a kitchen timer, was found to pose no danger to the aircraft or its passengers, Air France chief executive Frederic Gagey said. He said the item had been placed in a toilet cupboard by one of the passengers and said the bomb scare appeared to be the result of a 'bad joke'."
