Chas.E: You apparently don’t know what you’re talking about. So let me fill you in.
First, you don’t get your license revoked for losing your medical. All you have to do is take the medical, and your license becomes automatically valid.
Pilot’s licenses are issued for life. However, in the U.S. you have to take a biennial flight review in order to keep it current. If you haven’t flown for 40 years, as far as I know all you need to do is update your medical, do the BFR, and off you go.
However, there’s another matter of whether or not Bush even has a pilot’s license. Military pilots do not automatically get civilian licenses, mainly because they haven’t necessarily learned all the civilian flight rules.
I’m not sure exactly what military pilots have to do to get their civilian licenses in the U.S., since I’m only familiar with Canadian rules. Here in Canada, they just have to pass the written exam and do a flight test.
However, another wrinkle is that Bush as commander in chief could probably fly any military airplane that he’s qualified for. In this case, that would be none. But it wouldn’t necessarily take him that long to get current - learning the new avionics would be the toughest part.
As for whether the Secret Service would stop him, I seriously doubt it. He’s not a prisoner. Reagan used to ride horses on his ranch, and that’s a hell of a lot more dangerous than flying a Cessna, which is only slightly more dangerous than driving a car. Besides, why do think that it would be dangerous for him to fly an airplane, when he flies around in military aircraft all the time? He’s a multi-thousand hour fighter pilot that could be as qualified as some of the people flying him around, if he were current.
But Bush is far more constrained by public opinion. If he is seen doing something that is considered reckless, he’d be raked over the coals for it. So it ain’t gonna happen.
