True, but PPL level training isn't really about commercial flying anyway.
Emayhew - your commitment to learning to fly is a positive factor so don't worry about what the military will think.
Have you passed the aptitude tests at Cranwell yet? Just because you have a PPL, doesn't mean you are suitable for military flying so get that done before spending money on PPLH. You also need to pass the Admiralty Interview Board before you can taken in and that has little to do with aviation and a lot to do with leadership and personality. Those are your first hurdles to clear.
