The narrator of the documentary explains, “She mistakenly seems to think everything is OK, but in fact it’s taken longer for the message to arrive than the sound of the implosion. Everyone onboard is dead.”
The sub’s implosion occurred approximately one hour and 45 minutes into its two-and-a-half-hour descent.
At the time, it was not immediately clear what had happened, prompting a large-scale search and rescue operation.
The Titan was initially declared missing, and the U.S. Coast Guard launched a search on June 19, 2023. On June 21, sonar teams detected unexplained “banging noises” that led to false hope the crew might be alive.
However, by June 22—the projected point at which the sub’s 96-hour oxygen supply would have expired—officials feared the worst.
The wreckage was discovered on the ocean floor later that day, confirming that all five passengers had perished.
Implosion: The Titanic Sub Disaster documents not only the technical failure but also the emotional toll the incident has had on families and investigators alike.
