At the age of sixteen, I went solo with the ATC at south Cerney. It took me thirty launches because I had a problem with 'Cable breaks'.
I then joined a civilian gliding club before joining the RAF & most took the piss out of my 'Two gulled' badge. In a way, they were both right & wrong at the same time. They were wrong because the air cadet organisation put many thousands of cadets to a very basic 'Solo standard' for free.
They were right in saying in saying that it was a 'Very basic gliding thing'.
I did a lot more gliding in the RAFGSA, but always hated cable breaks, once up & away, all is just fine.
