A TITANIC submarine with five passengers on board also vanished for HOURS on another expedition last year.
An ex-passenger who embarked on a voyage to see the wreckage of the Titanic said the vessel was “lost” because of bad weather last summer.
Passengers on the trip, including CBS Sunday Morning reporter David Pogue, never had the chance to see the shipwreck after they lost communication with the surface ship.
"You may remember that the @OceanGateExped sub to the #Titanic got lost for a few hours LAST summer, too, when I was aboard," Pogue said on Twitter.
In the resurfaced clip of the expedition, Pogue says: "There's no GPS underwater, so the surface ship is supposed to guide the ship to the shipwreck by sending text messages.
“But on this dive, communication somehow broke down. The sub never found the wreck."

Pogue had raised safety concerns about the now-missing vessel, commenting that it appeared "improvised".
Asked on Monday if the five people on the current trip could survive, Pogue said: "Communication with the sub is lost... AND they don’t know where it is.
"Yes, they could still be OK. They have 4 days of oxygen, and 7 ways to rise to the surface. The question is, why HAVEN’T they?"
In the CBS clip, investment firm CEO Shrenik Baldota - who was on the 2022 voyage - can be heard saying: "We were lost. We were lost for two and a half hours."

Rescue crews are now frantically searching the Atlantic Ocean after the submarine again vanished on Sunday.
The sub set sail from St John's in Newfoundland at around 4am on Sunday.
Just one hour and 45 minutes into the expedition the submarine lost contact with its transport vessel - the Polar Prince.
Last on Sunday night, the vessel was reported “overdue”.
It’s believed this is when the alarm was raised and the Coast Guard were notified.
OceanGate, one of few companies offering trips to see the ruins, confirmed a major search mission has been launched to "bring the crew back safely".
