As a passenger, I'm no great fan of Ryanair. But that is purely an opionion, and has nothing to do with the professionalism of their flight deck crew.
I can honestly say that I find flying with Ryanair, no different to being on board an aircraft of any other carrier. It doesn't feel faster, the landings aren't any harder. Ok, I may have seen the odd FR taxiing a wee bit fast, but then I've also seen the same thing with EI, BA and EZY.
I'm afriad that I find all this talk about fast approaches, a little hard to believe. I'm sure that Ryanair have the same "stable approach" criteria, as any other 738 operator. The whole concept of 738's screaming down the glideslope at 300 kts just sounds a bit far-fetched to me.
My qualifications only extend to light aircraft, so maybe I'm not qualified to pass judgment, but I can't see any justification for some of the comments that I've read on this post.
