The effort to find the vessel and thereported noises resembling knockingin the search areaare also addressed in the new documentary.

In a previously-released trailer for the doc, a narrator recalled the hopeful reports of banging in 30-minute increments before playing the eerie audio.

“The symmetry between those knockings is very unusual,” former Navy submarine Captain Ryan Ramsey said. “It’s rhythmic, it’s like somebody is making that sound, and the fact that it is repeated is really unusual.”

Shortly after, U.S. Coast Guard Petty Officer 3rd Class Briana Carter told PEOPLE the notion that those noises came from inside the vesselwere not true.

“We don’t have anything at this time indicating any implosion or banging,” Carter said on June 21, three days after the submarine disappeared.

On June 22, when the Coast Guard announced that all five passengers were presumed dead, officials said that the reports of “banging” sounds discovered earlier in the week were likely not sounds coming from theTitan,asthey were not consistent with a “catastrophic implosion.”
