I'm sure it is because of his celebrity status. This is, after all, Massachusetts. If a kennedy can't get elected here, he moves to Rhode Island! The newshounds were on his butt the second they announced he was leaving the hospital. They had a large contingent of State Police at the door to keep them at bay.
Though my friends disagree with me, I think the TFR is unwarranted. What they should do is enforce the rules the FAA has. Smack them news hounds hard for violations and they won't ever do it again. (by hard, remember what the FAA did to Southwest.)
My problem with all this is that it isn't like the man is convalescing at home. He is out sailing on his boat; not trying to hide. He is milking this for all it's worth and the FAA has just fallen for it hook line and sinker. He'll grand stand this for all the attention and free publicity he can get.
Do not get me wrong. I wish him well as I do most people suffering from such an insidious malady. I know too many people who have passed on because of cancer and many who are receiving treatment for it not to. But please, the TFR is totally unwarranted. See and avoid!
