There had been many injuries caused by letter bombs. A very famous letter bombmaker is Ted Kaczynski, the so-called "Unabomber", who sent a series of letter bombs between 1978 and 1995, killing three people (all men) and injuring 23. One package, however, exploded onboard an airplane, which could have killed all the passengers and personnel, but it only caused an emergency landing. He stopped sending bombs after the New York Times accepted to publish a text he had written called "Industrial Society and its Future".
