Susie Millar on her Titanic engineer great-grandfather
It's 100 years since the launch of the Titanic in Belfast.
Susie Millar's great-grandfather helped build the Titanic and was also on board when she sank, killing 1,517 passengers and crew.
"We can look back on the achievements of the engineering that went into Titanic," Millar told BBC Radio 5 live.
"[But] two weeks after she left Belfast she was at the bottom of the ocean," she explained to Rachel Burden on 5 live Breakfast.
