Delays are not expected through the weekend for Thanksgiving travel. As noted in a previous column, on Thanksgiving Eve 1971, travelers were inconvenienced because of one passenger. Over the Pacific Northwest, D.B. Cooper opened the aft door of a Northwest Airlines Jet and jumped into a sky filled with cold, freezing rain. Earlier that evening, he handed flight attendant Flo Schaffner a hijacking note, opened a brief case to reveal a battery and wired red tubes. He demanded four parachutes and $200,000 in $20 bills to be delivered upon landing in Seattle. All passengers were released; the plane refueled and took off. He ordered the cabin not be pressurized. On Thanksgiving Day 1971, the rugged Washington State forest was extensively searched; Cooper was never found. Fastcast: Perfect.
