I don't recall a requirement for A levels at all let alone one in Maths or a science. I managed to get on the course with only an A level in Engineering drawing.
Maybe (all due respect meant), that the perceived academic level of GCSE levels by employers mean that they require A levels now, where in our day, O levels were seen as an adequate level of education.
Notwithstanding, this is going to be interesting if anybody tests the Law regarding age discrimination. After all, anybody can apply, The Air League and Bristow will still make the decision who they want. It would be impossible to prove that they were not doing anything other than a skills and aptitude based selection process.
