If it's as you say historical problems. Why is it necessary to go on a local radio to talk about them.
If you are going to be specific about an airline then His identity and experience is totally relevant. No one knows who or what he is. Or more importantly his experience. Again, very important before someone goes public with their opinion.
The CAA, AAIB and flight safety department can ask questions. Again it doesn't need a local radio DJ to do that.
Anyway, don't reply to this. I'm not going to respond further to your drivel either.
