On December 29, 1975, a bomb detonated near the TWA baggage reclaim terminal at LaGuardia Airport in New York City. The blast killed 11 people and seriously injured 74. The perpetrators were never identified. The attack occurred during a four-year period of heightened terrorism within the United States: 1975 was especially volatile, with bombings in New York City and Washington, D.C., and two assassination attempts on President Gerald Ford.The LaGuardia Airport bombing was at the time the deadliest attack by a non-state actor to occur on American soil since the 1927 Bath School bombings, which killed 44 people. It was the deadliest attack in New York City since the 1920 Wall Street bombing, which killed 38 people, until the September 11 attacks in 2001.
