Ok maybe a bad choice of words, which has ruffled a few feathers - for the wrong reasons. But, abuse of mods via PM's will you get you nowhere except the sin bin. Mods are here to contain dubious (or libellous) posts on behalf of the owners of the site. The rules are not made by moderators - and you signed up to them when you joined PPRuNe.
The ARPI story is well known and has been discussed here a few times before. This time around a suggestion that book research is involved. PPRuNe is not for research for books. We don't allow it.
The personal attacks via PM's is a no no, and now ignored, but should they occur again the writer will be banned without any questions or answers.
Stick to debating the subject now that I have re-opend the thread but please heed my comments.
You might care to know, or not, that I started this forum many years ago so that aviation history and its nostalgic aspects could have a place to enjoy, so in answer to one particularly offensive PM that I know nothing of aviation is mistaken. My years of flying numerous types, displaying, and running airlines adds up to knowing something of the industry in the past 50 years plus.
