Just to save people trouble -
I have already looked for related papers from about the authors, for about half of the presentations on the WWW. None are yet there. Cox might well have been reporting on the work of the RAeS FOG group with which he has been involved. There is a report on his company's WWW site about their work on upset recovery, unfortunately undated.
It may be that AIAA requires the authors of their indexed papers to surrender copyright; this is usual amongst U.S. professional societies. In which case you generally won't find the originals elsewhere than on the AIAA site. NASA appears to be an exception. I am not a member but I can ask.
