Obs Cop, your facts re military pilots' qualifications are wrong, at least for the Navy and RAF. For these you will need
at least two A-levels, as well as the five GCSE's, which must include Maths and English, at grade C or higher. A degree is not yet required, but may well be before long.
I'm not so familiar with Army requirements, but I'm sure their website will provide the latest info. As Army pilots need not be commissioned (and may spend a very short part of their career in aviation), I would expect the minimum qualifications to be lower.
