Talking about OZ flight strips.. does anyone recall the game of 30 years ago where strip holders were placed side by side in a long line with every other one upside down so they all locked together.. then you inserted your finger nails in the end ones and tried to lift them?? I recall the record was held by an Oz ATCO who lifted 43, which means he was Superman! My Supervisor at the time tried it with about 30 and pulled all his finger nails off. We laughed all night!!!
