It could be nothing but perhaps flying isn’t doing her health any good. Someone mentioned this on one of the health threads. She was flying when she commented on the NYC bombing so she has been on occasion doing so but she didn’t look too perky when she did. She was in Philly yesterday but it might have been ground transport from NYC rather than air but who knows.
At age 73 I’ve come not to like flying at all, even though much of mine is first class. One of the big problems is the air pressure changes. It’s twice as bad when I have to change planes. Now imagine a sick, old woman having to go through several pressure cycles a day for months at a time. Not a fun experience.
Oh, Bull**it. I have almost 10,000 hours as an aircrewman and know guys who have three times that total. None of us does a “Hillary!”
