Mother sacrifices own trip on Titanic sub for son's dream

Christine Dawood, whose husband and son died on OceanGate's submersible that imploded on-route to the Titanic wreckage, revealed in an interview that she had planned to be on board but let her teenage son go in her place. Dawood said she is "coping" but not doing very well after living through the horrific tragedy of losing both her husband and son. Authorities are investigating OceanGate's operation since the submersible went missing on June 18, and it was confirmed on June 22 that all those on board died in a catastrophic implosion near the Titanic wreckage.
