On September the 15th, 1976, the Belfast Telegraph offices in Belfast centre was bombed by the Provisional IRA.
Journalists were clattering at their typewriters when the second evacuation warning of the day went out on the Tannoy. Following the evacuation, a bomb in a van exploded in a loading bay, before many employees had the chance to get out.
One of them – 64-year-old production worker Joe Paton - who'd been in a locker room above the bay - died from his injuries four days later.
Ciarán Dunbar is joined by former Belfast Telegraph journalists Billy Graham and Alf McCreary, who were there on the day.
