From the PBS website:
“When filmmaker Ken Dornstein was 19 years old, his older brother David was one of 189 Americans killed in the bombing of Pan Am Flight 103 over Lockerbie, Scotland.
Nearly three decades later, only one suspect, a Libyan man, was ever convicted of the terror plot, which killed 270 people in total. Abdel Basset Ali al-Megrahi was sentenced to life in prison but later released; who else was involved remains an open question.”
