Somebody earlier brought up the Titanic as an analogy, and others have said that Ryanair has an impressive safety record. Some words to consider...
"When anyone asks me how I can best describe my experiences of nearly forty years at sea, I merely say uneventful. I have never been in an accident of any sort worth speaking about....I never saw a wreck and have never been wrecked, nor was I ever in any predicament that threatened to end in disaster of any sort."
Captain Edward J Smith, RMS TITANIC
Time will tell.
