I doubt he explicitly gave permission for that either.
I'm sure Tony Blair gave express permission for the medical records to be released and no doubt used the spin to his advantage somewhere along the line.
What I am worried about is the "yea but no but bloke in the pub told me, this geezer right, he had an XYZ done on his heart and he flies the space shuttle...." gets translated to "The medical records were made public"...
I should have asked if there was any hope of getting cleared after demonstrating a degree of fitness, because writing this has just shattered a dream of wnnng the Lottery and flying my own Mosquito.
You can always come and fly mine if I win the lottery, but if not, have a look at the FAA who have a pragmatic view on conditions like these. You can even get back your class 1 FAA (after various tests) and fly a United B777 from LHR to LAX as Captain after all sorts of heart surgery, including conditions mentioned in these threads.
