Twenty-eight years for Pan Am 103, fifty and counting on the Kennedy assassination, just fifteen with the downing of TWA 800. That one may get resolved before all he!! breaks loose in the next and final ME conflict, although I have my doubts.
Col. "Bo" Gritz, no flaming liberal he, had it pegged within days of the bombing as Iran's doing, in retaliation for the accidental shoot-down of an Iranian civil aviation Airbus by our Navy six months earlier. But then nobody would take seriously a "conspiracy theorist."
CORRECTION: That would be 18 years this coming July for TWA flight 800. (memory lapse)
I thought the same thing: tit-for tat.
