GEP has said several times that the pilot/instructor told him that she had a disqualifying medical condition.
What I don't understand about this thread is why some people seem to believe that she has chosen to tell GEP something that is untrue.
I believe that Indy's medical condition is indeed confidential - up until the point where she tells others about it and particularly if she tells them that she is disregarding the consequences of it. After that, I can't see why anybody objects when her plan of action is made public. You do not sidle up to somebody who has a reputation for upholding the rules and mention your disregard for them without expecting a reaction.
If GEP has deliberately been told a falsehood in order to precipitate a response so that he can be "shot at", then there is more to this thread than the subject under discussion.
