Timeline of airliner bombing attacks

Commercial 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.
