LONGVIEW, Wash. (AP) -- The Washington State History Museum in Tacoma plans to open an exhibit in August of next year on the D.B. Cooper skyjacking mystery.
State Historical Society Director Jennifer Kilmer tells The Daily News (http://is.gd/PkXK5o) it's part of an emphasis on more contemporary events.
A man identifying himself as Dan Cooper hijacked a Portland to Seattle flight in November 1971. He picked up $200,000 in ransom money in Seattle and took off for Mexico, then parachuted somewhere over southwest Washington.
The skyjacking remains unsolved, but some of the marked $20 bills he was given were found in 1980 along the Columbia River.
The exhibit will include some of the money. It also will illustrate features of an old Boeing 727 that have been changed in modern planes to prevent skyjackings.
