Three years ago, OceanGate’s Titan submersible imploded while on a journey to view the wreck of the Titanic, killing all five people on board.
Christine Dawood's 48-year-old husband and 19-year-old son, Suleman and Shazhana Dawood, were among the people killed on the historic dive trip.
Dawood has since shared her story of that week, and the subsequent grief following her losses, in a new memoir - 96 Hours.
"Even though, obviously, we knew they are not here, that they were missing - sometimes, speaking out, the reality hits you and you don't want it to be true."
