A total of 270 people were killed when Pan Am Flight 103 exploded over Lockerbie on December 21, 1988.
Abdelbasset Ali Mohmed al Megrahi was convicted of the bombing and sentenced to life imprisonment in 2001. He was released on compassionate grounds in August 2009 after being diagnosed with terminal cancer and was returned to Libya. At the time, doctors estimated he had three months to live. He is still alive.
