Maybe going slightly off thread, but I have seen this issue of Professional Pilots only on PPrune before.
Its obviously up to Danny how he plays with his own train set but I for one would welcome a public forum solely for Professional Pilots. (There is an awfully high ratio of chaff to wheat on it at the moment and has been for a long time. This problem is getting worse.) Failing that, perhaps we could rename PPRUNE as something that more accurately reflects the background of its contributors.
