This Day in Failure: September 29

1982: The first of six people die from cyanide poisoning in Chicago. Two days later, police determine that the victims ingested the lethal compound by taking Tylenol tablets laced with the poison. The perpetrator is never found, but the incidents lead to the introduction of effective, albeit expensive, product safety seals.

1957: A passenger train traveling at full speed collides with a stationary oil-tanker train in the Gambar province of western Pakistan, killing 300 people and seriously injuring 150 more.
