The passengers that died on the Titan submersible would have been aware of the impending catastrophe for a minute before the implosion, an expert has said.
Spanish submarine expert José Luis Martín suggested the submersible lost stability due to an electrical failure that left it without propulsion, causing it to fall toward the seabed 'like an arrow vertically' with its porthole facing down.
'The Titan changed position and fell like an arrow vertically, because the 400 kilos of passengers that were in the porthole compromised the submarine. They all rushed and crowded on top of each other,' Martín added.
'Imagine the horror, the fear and the agony. It must have been like a horror movie.'
Due to the depth and the lack of both natural light and electricity, the group would have been in total darkness as they sank toward the bottom of the Atlantic, he said. He estimated that the sub began freefalling at a depth of around 5,600 feet and fell 'as if it were a stone and without any control' for about 3,000 feet until at around 8,600 feet it 'popped like a balloon' due to the rapidly changing pressure.
Martin suggested the passengers would have been piled on top of each other in terrifying total darkness throughout the fall, which would have lasted between 48 and 71 seconds.
The Titan submersible lost communications with its support vessel on Sunday, June 18, during a descent to the wreck of the Titanic 12,500 feet beneath the surface.
Days later, its debris was recovered. It was said to have suffered a 'catastrophic implosion'.
Tourists Hamish Harding, 58, Shahzada Dawood, 48, and his son Sulaiman Dawood, 19, French Navy pilot Paul-Henry (PH) Nargeolet and OceanGate CEO Stockton Rush all died on the submersible.

Amazing the pools still have water in them
E-Ticket!
My visions of this were almost on target. I saw them dropping at too fast a rate which would cause the pressure change to increase too rapidly. The only other thing was I thought was that it was the thrusters that were malfunctioning causing their rapid decent. Horrific.
“’popped like a balloon’ due to the rapidly changing pressure.”
Submarine expert, eh?
Last time I saw a balloon implode was...never!
I don’t believe it either.
At that depth, 400 kilos on the nose is nothing at all compared to the outside pressure.
Not even close.
Yes
In my mind I always thought that the Thresher and Scorpion did implode. RIP sailors. This story seems well thought out and I think that it is plausible.
Perhaps instead of laughter it was a heavy sigh
“What the article says is plausible. So if there were no electrical failure leading to rapid descent”
I don’t think so. Electrics weren’t holding in position, so no electricity doesn’t mean it plummets down. Not to mention a shift in GC means nothing.
👍👍
Thresher likely sank below crush depth as near as I can tell. Probably was taking on water and couldn’t hold. Two or three garbled messages after one or two clear ones.
I saw video of the Scorpion wreckage - if she did that 180 after ejecting a hot torpedo it would make sense.

(Transcribed from the text within the 2 images at the Twitter link. I included depths in feet and rates of descent and ascent. "RTM" is the Real Time Hull Health Monitoring System.)
[07:52:34][Top] clear for descent. Enjoy the ride.
[07:54:07][SUB] Descending now
[07:58:16][SUB] Launch sequence complete, rdy?
[08:00:39][Top] all clear
[08:01:11][SUB] Proceeding.
[08:03:09][Top] Enjoy the dive gentlemen.
[08:19:53][Top] you're 15 minutes into the dive, current depth. Systems check, please.
[08:21:28][SUB] Systems check complete,all in order. All lights are green. We are 756, proceeding. (2,480 ft)
[08:22:41][Top] Thank you. Proceed.
[08:34:02][Top] 30 minutes in, update please.
[08:34:57][SUB] All systems are functioning normally. We're in good shape. Continuing our descent as planned.
[08:36:05][Top] Superb, proceed.
[08:49:10][Top] Over 45-minute mark. Current depth? Confirm status.
[08:51:30][SUB] Depth at 1934. All systems stable and descent continuing as planned. Happy crew. (6,345 ft)
[08:52:28][Top] Excellent!
[09:01:46][Top] You're at the hour mark.
[09:02:13][SUB] All is smooth sailing here.
[09:15:21][Top] You are at 75 minutes, depth? Status? Do you need to adjust velocity?
[09:17:50][SUB] All under control. At 2960. No adjustments needed. We're enjoying the ride. (9,711 ft - rate of descent approx. 2.13 ft per second)
[09:19:03][Top] Understood
[09:28:16][SUB] we're noting an alarm from the rtm

[09:57:22][Top] Please respond if you're able.
That’s awesome
I couldn’t quite make out the end of the Ben Hur joke.
Exactly. This is disaster porn. Let them rest in peace at this point.
Why does the new Spanish Navy have glass bottom submarines? So the new Spanish Navy can get a good look at the old Spanish Navy.
It was all lights were red and then it imploded. There was no fast dive.
The expert says it popped like a balloon? He is discredited right there for obvious reasons of physics.
Spanish submarine expert? Isn’t that about on par with a North Korean aeronautical engineer? I mean, their rockets fly so well.
This article and so-called sub expert is rubbish.
No kidding
I stopped reading after that...
