Not to worry, that image was shared with the press. Sat images were made public 1-2 days after the collapse, only I don't know exactly which days they were taken. I suppose only paying customers get to know that...
There are only a handful of 30-50cm imaging satellites, and depending on...
How so? What's the peak transient force coming from a jackhammer removing old roof material that contacts bare concrete? Wouldn't that force transmit down the whole column? It would seem to me that an anchor test would at most place 5000 lbs of lateral load on the roof slab, even if one of the...
I see no issue with stairs exiting directly to the pool plaza. Having to go through the lobby interior is more dangerous in a fire. In collapses/quakes, the front lobby doors wouldn't have been safe because there'd be a building above you; pool plaza would be the fastest way to get away, and...
14 miles away is the Miami International Airport weather station. Preceding the collapse there was about 1/3 inch of rain in the 5-7pm timeframe and a mild <10mph easterly breeze (that means going from east to west). Air temperature was a pretty constant 81 F...
There was lack of emergency notice. We know the silent alarm was triggered by 1:16:39 am courtesy of the 911 alarm company call. The building didn't collapse until ~1:22:20 am. Usually those alarm systems progress to full alarm within 3 minutes. It's possible someone silenced it seeing as it was...
Probably not; Prieto is a common Spanish surname. The owner of the adjacent unit 1112 is better known, though. Annette Goldstein, former board member ca. 2019, daughter of builder Nathan Goldlist ... Nathan Reiber and the Goldlists met up in Canada.
Missing/disorganized building records at a commercial storage facility rented to former Surfside inspector... the plot thickens

Looks too thick to be a floor or balcony slab. I'm thinking it's part of the eastern sheer wall with the 13th floor being thinner just the way it is on the west. That would imply the 2nd portion of the collapse - the north side - also ripped part of the east wall just as the 1st portion ripped...
@spsalso got me thinking:
I'm more inclined to believe the power was out than Eric Zion was making this all up for insurance or whatever. The primary reason was that Eric & wife were renting. Additionally, it seems other Zions had rented the place and seemed to be on good terms with the...
What a good interview... (incognito if you have to)

Vach almost makes it seem like we handled the concrete debris and they handled recovering the people. I hope we...
The type of enhancement is critical. Knowing the context of an image or video and the mechanisms of each enhancement is part of being a photo forensic analyst. Otherwise one could generate highly misleading pictures by blindly using the same tools the professionals use. In recent years AI-based...
Well, I felt most of us already saw the penthouse roof shape in the original Twitter video...
The TODAY video is just a reproduction of the same phone recording that WSVN published, but zoomed in slightly and color adjusted. I think the dead giveaway is that you can still hear the "botanical...
It's just dust, same on hood & side panels. Airbags aren't supposed to deploy on parked cars - no electrical power to the triggers. Though there are explosives within airbags, the plaza collapse air boom would hardly register, wouldn't even crack the windshield.
cl = centiliter?
Then 1 cl = 10 cm^3
Your calculations were otherwise correct for the density of that mix. Keep in mind powder contains some air. It's typically 1-1.3 g / cm3 for blasting powders, 1.57 for C4.
I'm not sure how the bomb techs miscalculated by 3x after x-raying. It's possible...

Another condo evacuation over questionable garage columns. Three-story, built 70 years ago, 93rd & Collins... Evacuation wasn't mandatory; residents are just going ahead with it. The...
I don't get the purpose of the Powerpoint. Wouldn't it be better to interview all the workers/inspectors up there in the 1-2 weeks preceding failure, ask them how many people were up there, what were they doing, what equipment they brought up/down, and cross check with notes, communications...
So many seem to conflate temporal proximity with causation. Anchor load testing is not column load. It's tying two roof points with a chain hoist, thereby compressing roof slab laterally. If it doesn't crack then, it's really hard to believe it would crack with no load that very night. Anchors...
You make excellent points about snapshot/narrative and cohorts, though to me it's clear Gabe and Chani are English native. Only their mother isn't. Times of Israel is a news aggregator; sometimes editors at such sites will add their own spin... but their primary source could as well have been...
It's right around the intended maintenance parking:
