Who will spare me from this turbulent moderator?
The thread has not been hijacked. It has gone off at slight, but more interesting tangent. This is how conversation works in real life and is one of reasons that pprune is such a good site. When the thread gets boring, people will stop reading and it will die its own little death. It doesn't need intervention from any control freaks who think they know best.
If the original poster wants to put a reply asking people to get back to his topic, then fair enough. (Although what more can be said I don't know).
Yellow card indeed.
Now about that crap magazine....
