Not surprised that something like this has finally happened. - there is no smoke without fire though. I suspect that there will be elements of fact and fiction in the show. Either way publishing these letters will do only one thing and that is make sure that many more people will watch the program than might have done without all the extra publicity. I would think Dispatches will be delighted.
I also wonder what it would actually take to convince a bully like MOL that there might be something wrong with his airline and the issues of fatigue that the program appears to be about raise are very much part of the industry today. People should be aware that those at the pointy end are often shattered and fatigued - most airlines seem to see legal limits as targets rather than guidelines but I am sure that debate has been had somewhere else before on pprune.
