This thread was started over a year ago and contains the total postings that the OP has made on Pprune - with one exception which is the one that Bealzebub has copied in above.
It has been recently resurrected but offers no additional rational information. The only thing it has done is generate a complaint from the OP to Moderators about the negative responses he is seeing here.
Each poster is entitled to their own opinion. As Moderators we will ensure that happens without flaming or the like. To stop this thread going that way I am closing it.
