Seems to me (as an outsider) that there's truth on both sides here. Yes, it could, and does, happen to anyone; but it does seem to me that we read about it happening to Ryanair more than most. Could be a bunch of reasons: number of flights, use of small airports, penchant for high taxi speeds, schadenfreude among the RYR haters on PPruNE, to name but a few. Take your pick.
