I'm not based in the CI and have only been copied in on some correspondance by some of the guys I know there, and, of course, could only refer to private emails in a public forum where I had the sender's explicit permission.
I have a feeling that many letters have been sent recently and don't know what replies, if any, have been received as yet. The only stuff I am aware of in the public domain is the Airport's
PR statement, and the press quotes in the last week or two.
