Don't you think that if there were safety issues something would have happened?
I visit PPRuNe regularly in order to check if something has happened yet, although my focus isn't Easyjet or Ryanair, it's all flavours (not just low cost) of another shambles I'm very familiar with. The pressures of the low cost version must inevitably stack the odds higher, though.
Beats me why there aren't craters everywhere. There have been a few, for reasons never properly revealed, I think. They've come close on other occasions, but got away with it. Maybe it's like buses.....none for ages, then a whole bunch at once. It's certainly an ongoing mystery.
Of course, the CAA (or whatever) won't be doing anything about it. "No prangs, no problem" is the perfectly understandable easy option. Being proactive requires an incentive and the public sector doesn't work like that.
