Ryanair is as good as any airline in the country, and I don't work for them. I commuted weekly with them and was perfectly happy, and I work in the industry.
Whilst you feel your question is necessary, that's it. There is no justification for casting doubt on their saafety. If you are too nervous, either go by train or pluck up the courage to fly, but please don't keep bleeding about it in a professional pilots forum. You have your answer- if you are still too afraid, then don't fly. It's quite simple. If you can get yourself on the aeroplane, don't make a scene. You have to remember the staff on those planes are happy to fly every day of their working lives!
