Timeline of airliner bombing attacks
Passenger airliners as well as cargo aircraft have been the subject of plots or attacked by bombs and fire since the near the start of air travel. Many early bombings were suicides or schemes for insurance money, but in the latter part of the 20th century, political and religious militant terrorism became the dominant motive for attacking large jets. One list describes 86 cases related to airliner bombings, 53 of them resulting in deaths.
List of incidents
- United Airlines Chesterton Crash 1933 Boeing 247 was destroyed by a bomb, with nitroglycerin as the probable explosive agent. A Chicago gangland murder was suspected, but the case remains unsolved. It is thought to be the first proven act of air sabotage in the history of commercial aviation.

Due to lack of evidence, the suspect was never charged in the alleged bombing, and no probable cause for the crash was found.
- Continental Airlines Flight 11, registration N70775, was a Boeing 707 aircraft which exploded on May 22, 1962 in the vicinity of Centerville, Iowa, while en route from O'Hare Airport, Chicago, Illinois, to Kansas City, Missouri.
