Thanks for posting that ST, I found it interesting to hear his view on Rendlesham. He sounded quite confident about this explanation.
Why don't you ask them using the FOIA, you probably stand a better chance as a film maker than us lesser mortals. I suspect it will be like getting blood out of a stone but worth a try.
Obs, being a lesser mortal myself, I'm not sure I would have any influence over their decision to release documents. I believe that Chuck De Caros questions relating to the whereabouts of records on this case, have still gone unanswered after all this time. Which is pretty hard to believe.
On the chemical weapons accident theory that you and Puddle have put forward, I think it would be an idea to search through Suffolk County records looking for localised contamination, if you haven't already?
