You could contact Dr David Newman from Flight Medicine Systems. I am sorry but I can't post links yet.
He is ex RAAF.
Even though it is an Australian company Dave is "Visiting Professor of Aerospace Medicine at King’s College London, in the Centre for Human and Applied Physiological Sciences".
He is very approachable and a nice bloke. I think he could steer you towards some names in UK that may be able to help.

Thank you kindly for the info. Another potential route for some info.
