'Haze' is correct. The original was written for the occasion of the repatriation of the Duke of Windsor. I had to re-write it in 92 and it became Operation Overstudy because The Queen's Flight were operating 146s and we were all getting a little concerned about the Queen Mum. Little did I know that the next time it was to be used was for Princess Diana (TQF having moved in the meantime to Northolt); hence my claim to fame having been involved in Princess Diana's first military engagement as Parade Commander (Hon Air Cdre at Wittering) and her last (Op Overstudy author).
There was a suite maintained in the Officers' Mess at Benson for any of the Royal party who were likely to stay overnight and it was called the Haze Suite. Funnily enough they didn't change the name to the Overstudy Suite when the Op Order changed.
My last night in the RAF was spent in the Haze Suite before I buggered off to Oz.
