During the 1950s we were spoilt for choice. 24F squadron ATC organised at least 2 weekend trips a month for those who cared to go aloft. My first trip was in a Lancaster, followed the same day by an Oxford. I couldn't go often enough and was staggered when other cadets declined trips by saying "Oh, not another bloody Shackleton, we flew in them last time"! They usually attended summer camp though as the aim was to get more types in the little book we were issued with. (Wish I had kept mine).
