I've always found it absolutely astounding that the most highly trained and skilled individuals in the military (pilots of course!) leave with not a single recognisable civilian qualification.
The hoops are not impossible, though, and the fact that plenty of my RW mates have made it into the LHS for (amongst others) BA, Virgin and BMI despite (in most cases) no FW* hours in the RN suggests that it's not all bad news.
Edit * Not counting the 90 odd (as it was) FW hours on Flying Grading and EFT.
