Air Florida Flight 90 Crashes into Potomac River

On a snowy afternoon in Washington, D.C., Air Florida Flight 90, a Boeing 737-200 bound for Florida, took off from National Airport after prolonged ground operations in freezing conditions without proper engine anti-ice activation or wing de-icing. The aircraft stalled shortly after liftoff due to ice accumulation and thrust misreadings, striking the crowded 14th Street Bridge and plunging into the icy Potomac River. Of the 79 people aboard, only five survived the initial impact and frigid waters; four motorists on the bridge also died. The NTSB investigation later pinpointed pilot error, including failure to reject takeoff despite instrument anomalies and inadequate preflight procedures in the storm.

Space Shuttle Challenger Explodes After Liftoff

NASA's Space Shuttle program aimed to make routine human access to orbit a reality during the 1980s, with teacher Christa McAuliffe selected as the first civilian passenger for mission STS-51L to inspire students. On a cold morning at Kennedy Space Center in Florida, Challenger lifted off at 11:38 a.m. EST on January 28, 1986. Seventy-three seconds into flight, a failure in the right solid rocket booster's O-ring seal—exacerbated by low temperatures—allowed hot gases to escape and ignite the external fuel tank. The orbiter disintegrated, killing all seven crew members instantly as debris fell into the Atlantic Ocean. The tragedy grounded the shuttle fleet for nearly three years and prompted major safety reforms.

Civil Liberties Act Signed for Japanese American Redress

During World War II, the U.S. government interned over 120,000 Japanese Americans, two-thirds of them citizens, citing national security despite a lack of evidence of disloyalty. Decades later, the Commission on Wartime Relocation and Internment of Civilians documented the injustice as rooted in racial prejudice and wartime hysteria. After years of advocacy and legislation, Congress passed the Civil Liberties Act. On August 10, 1988, President Ronald Reagan signed the bill into law, authorizing a formal apology and $20,000 in reparations to each surviving internee or their heirs. The act also aimed to prevent similar violations of civil liberties in the future.
