I'm a very, very frequent traveller with Ryanair and I've just finished reading through the downloadable letters on their site regarding this matter. I have to say, it all seems a little overblown to me and the replies given by Ryanair seem to make perfect sense - with an obvious hint of spin.
It certainly hasn't worried or discouraged me, in any way, as a regular passenger with RYR.
I think though that, one the programme goes out, "Joe Public" may be alarmed a little bit, probably thanks in no small part to a clever editing process.
I remember, not too long ago, a similar programme reporting supposed security lapses at EGCC. That went out with a damp squib too and I think this may well do the same.
