Last flight from Saigon relived after 30 years
This weekend, the crew of "Clipper Unity," Pan Am's familiar Flight 842
and their Vietnamese baby refugees -- most of whom are now in their 30s
-- will reunite at the Crystal Gateway Marriott Hotel in Arlington for
a tearful anniversary of the celebrated evacuation, dubbed "Wings of
Freedom."
