As I recall; when a Cadet completed the three solo's not only was this a real ATC qualification but also the ability to apply for the BGA A&B Cert. So it seems that the BGA and ATC actually go back some time. In fact one could wear the little enamel badge on the uniform, and upgrade to the 3 Gull version after the 'soaring' trips on an advanced course.
My goodness they really did chuck so much away, and do not deserve to be part of the future. Time for break chaps; don't let the donkeys get their way (no disrespect to donkeys)
