There were rumours at my flight school about the old BA scheme. Allegedly if any male cadets underperformed or failed anything, they were dismissed. The females of course, weren't.
Nonsense - there were BA selected students of both gender who underperformed but were allowed to continue. I know of one male who despite numerous opportunities to discontinue training, was allowed to progress onto type training only to be chopped early on due to unsuitability. I heard the TRI's asked how he had been allowed to get that far and it has to be said, that's a pretty poor reflection on selection and basic training.
