ILUV2FLY,
Thanks for actually providing facts. All these "safety concerns" people apparently know about don't refer to any facts. If Ryanair's operation was as dodgy as people claim, the IAA would have stepped in long ago. This hasn't happened and according to their spokesperson there is nothing to be concerned about regarding safety.
As you say, 15 years of safe operations and 12m passengers p.a. speaks for itself.
