Saw/flew with lots of politicos into/out of DCA. Not sure that counts. (It

Ran into Tina Turner at Brussels in the EuroClass lounge some years back. Wasn't sure if it was her (pix always seem to emphasize the long legs) so asked, "Excuse me, you look familiar - aren't you Margaret Thatcher?" She was amused; her bodyguard, lurking in the vicinity, wasn't. Really a gracious person.
And philforest, if you sat up front with your wife in steerage and are still alive, you must have a most understanding frau.
