When I retired in 2002 the CAA wrote to me asking if they could pass on the results of all my aircrew medicals. This would have been from my initial in 1966 at Kelvin House when you spent a day with the RAF who sometimes referred people to Harley Street for a second opinion at no cost to the candidate, in my case a knee that had been embedded in a car sealed beam headlight unit. My referral took place the same day! The researchers must have had a field day.
Unfortunately I can't remember the name of the medical university that made this request but I think it might have been in Cambridge or London.
