The M62 coach bombing happened on 4 February 1974 on the M62 motorway in northern England, when a Provisional Irish Republican Army (IRA) bomb exploded in a coach carrying off-duty British Armed Forces personnel and their family members. Twelve people (nine soldiers, three civilians) were killed by the bomb, which consisted of 25 pounds (11 kg) of high explosive hidden in a luggage locker on the coach. Judith Ward was convicted of the crime later in 1974, but 18 years later the conviction was judged as wrongful and she was released from prison.
