On November 24, 1971, a man known today as D. B. Cooper hijacked a commercial flight between Portland and Seattle by threatening to blow up the plane unless he received $200,000. After landing to receive a ransom, he ordered the plane back into the air. Then the rear stairs of the 727 aircraft were lowered, and he parachuted into the night. He was never captured, and the case is still unsolved. This act hastened the age of airport security in which trust and confidence have been replaced by suspicion and fear. What he did affected us all.
