A continuation of our discussion of this failure. Best to read the other threads first to avoid rehashing things already discussed.

Thanks, Jeff. This is an easy one..

June 18, 2023
08:00 ET Submersible dives toward Titanic wreck located at a depth of 3,810 meters at 41°43′57” N 49°56′49” W
09:45 ET Submersible implodes at ~3,500 meters, failing both comm and tracking

Per James Cameron. Time stamps from Reuters.

I did hear it mentioned that the operator dumped ballast just as comm/tracking were lost. But I don’t have a credible source.

Sorry. Somehow I ended up on the MH page so I just quickly made an archive and shared it.

The Miami Herald second anniversary articles. Titles followed by links to archived versions of the articles and a very high level summary.

Two years after Surfside condo collapse: ‘We haven’t recovered. Don’t forget about us’
Gabe Nir is struggling with PTSD.​

‘How could we build over dead bodies?’ Some Surfside families want a memorial, answers
Martin Langesfeld cannot be mollified.​

Long road to healing: Surfside marks two years since devastating condo collapse
Various acknowledgements mark the anniversary.​

Loved ones honored the lives lost in Surfside. See photos of the touching ceremonies
Grieving people and politicians.​

It is interesting to note who is not interviewed for these articles. Iliana Monteagudo, Shamoka Furman, the Vazquezes, etc.

"Oh Charlie, can't you sharpen it?" Not sure this helps...

SFCharlie, as I review the issue of the column buckling, I've realized the line you pointed to is CMU infill between column lines. The column lines are associated with the broader infills, not the narrow ones.

au contraire. So to be clear the penthouse roof is seen hinged down with the far parapet visible. I don't think this quite as discernable before this enhanced image that I can recall. I believe I tended to think that was how it was but it seems clearer now. Or looking at it with my eyes crossed, does it appear the penthouse tilted north? I think the former is the most probable case. It would seem to be one or the other. Does that affect my vision?

Yes, That why I put "columns" in quotes, I was typing architecturally, not structurally. The CMU (cinder block in my time) explains why it went all wibblily wobblily, but does point to the distress the east portion of the tower was under.

To me, the "façade" (palisade?, south parapet, what ever) of the penthouse appears to have fallen straight down one story in the "late" frame...???

That's what I was trying not to see. That was not what I was thinking I should see. What accounts for the appearance that the penthouse looks like it is leaning/moving north?

Edit. well I thought of something anyway. That' a thin section of the penthouse. It's not too much to think that the east wall of the penthouse would fall that way at that location. South wall of penthouse falls north. I don't think it's that significant. The forces that are pulling that way are possibly related to the mode of the roof failing. But that is a guess.

I think y'all are trying to extract very precise information from an extremely imprecise source.

You're never going to get precise information from the low resolution, low framerate image produced by a camera at an unknown distance with unknown optical aberration and parallax characteristics. Those images are a general guideline, not more.
