You arent listening really are you JFZ90? Des said QinetiQ had said the fuel system was safe. QinetiQ actually said it was tolerably safe but not ALARP. ALARP is a fundamental part of the MoD's own definition of safe. Under those rules, a system cannot be safe without it. Tolerably safe is not good enough on its own. It must be ALARP. That's not my rules, that's the MoD's own rules.
