Oden, here's the link to an earlier discussion on here....
Concorde UK Observer Article.
Another way to find out if something has been discussed on PPRuNe before rather than an exploratory post, is to use the "Search" facility at the top of the page, or set your browser view back about a month.
Anyway, shutting this one down now, as it's a duplicate.
