The nuclear submarine USS Nautilus (SSN-571) became the first vessel to reach the geographic North Pole, completing a submerged transit from the Pacific to the Atlantic beneath the polar ice cap.

The Professional Air Traffic Controllers Organization launched a nationwide strike against the FAA, and President Reagan responded by ordering military air traffic controllers from the Air Force, Navy, and Coast Guard to help keep the national airspace system operational.
