When a plane from London reached in Sydney airport, workers began to unload the number of wooden boxes where contained clothing. No one could know why one of the boxes were extremely heavy. It suddenly occurred to one of the workers to open the box. He was astonished at what he found. A man was laying in the box on top of a pile of woolen goods. He was very surprised at being discovered that he did not even try to run away. Before he was arrested, the man admitted hiding in the box before the plane left for London. He had had a long and uncomfortable trip, for he had stayed the wooden box for over eighteen hours. The man was ordered to pay￡3,500 for the cost of the trip. The common price of a ticket is ￡2,000!
