I do think it is absolutely necessary to speak from personal experience when criticising a company's product. We can all trawl the press and blogs cuttin' 'n' a pastin' stories about how airline this and company that have failed a customer's expectations.
I appreciate that 10secondsurvey values his life, but who has died? If you've justified concerns about safety then why not register them with the authorities, or are they just stories you've heard from friends of friends?
I can only repeat that I've used Ryanair dozens of times and they've been OK and their destinations are ideal for me. If this changes then maybe I'll look to SNCF as an alternative. Meanwhile I honestly can't see the point of complaining about a company you never use and never have to use.
