FACT: GW Bush disobeyed a direct order from his TANG superior officer to report for his annual flight physical. As a result of not taking the physical, he was removed from flight status. Oddly enough, any documentation regarding any disciplinary action taken against him for disobeying that order has been strangely lost in the National Guard archives.
I don't know how they do things in Texas, but I do know that, throughout my service, if I had ever disobeyed a direct order from my superior officer, there would be a record of that in my service record and my career would have been over as of that moment.
