EIGHT-year-old Au Yeung Fong's dream had come true. Seated by the window in a Cathay Pacific Tri-Star passenger cabin - the primary two girl was waiting excitedly for the plane to take off. But one thing puzzled her. ''What do I do with this?'' she asked her mother next to her as she pointed to her seat belt. Mrs Au Yeung did not know, either, so she asked help from another passenger. It was the first time both mother and child had gone on a flight, thanks to Kinder Surprise Eggs. Fong was one of 125 lucky children who discovered a flight coupon inside a Kinder chocolate egg recently that entitled them to their dream prize of flying in an aeroplane, even though only for an hour. Kinder is an Italian chocolate maker. It's product manager, Ms Jennifer Leung said: ''Although Hongkong is a prosperous city, there are still many children who have not been on a plane before. To them, it's like a dream. That's why we organised the Kinder Surprise Fine Tour, to make their dream come true.'' Fifteen of the seats were reserved for the winners of a Chinese book-report contest organised by Television Broadcasting's children programme Fax A Song on Jade channel. Fong was one of them. ''She had always asked me when she's going to take an overseas flight,'' Mrs Au Yeung told Young Post . Motivated by the prize, Fong wrote her first book report about the adventure of two mice on an escapade from home. The weather was perfect on the day of flight. The children, from four to 14, were dressed in Kinder's Orange and White cartoon T-shirts and most of them were accompanied by a parent. For Primary 4 student Cheung Ho-man and his mother, it was in fact the first time they had entered Kai Tak Airport. ''It's big and it looks good!'' said nine-year-old Ho-man. Coco Chan Ching-yin, eight, on the other hand, said she felt 'a bit afraid of being high up in the air.'' But the little chocolate lover's cheerful face hardly showed it. Once airborne, many were fascinated to look down at the tiny ocean vessels dotting the sea as the plane flew over Kowloon City, Kowloon West, Tsuen Wan, and Lantau Island. After some happy munching over salmon sandwiches and almond cakes served by smiling air-hostesses, Fax A Song hosts Polly Wong Po-kwan and Rosalina Ng Ching-ching led in the singing of children's jingles. They sang ''It's a Small World After All'' but had to stop soon after because of the difficulty of getting such a large and spread-out crowd to sing together. A lucky draw followed. Winners received Kinder chocolates with an assembly of toy parts inside. When the aircraft touched down, little Isaac Tong told his mum, ''This is fun --but it's too short!''
