On the bridge of the container ship Dali, 4 minutes from disaster, there's one critical moment we haven't heard about yet.
The very moment the ship lost power the 1st time.
What did the pilot do, right then?
His first thought, apparently, was safety — the bridge looming ahead.

⤵️ NTSB photo of the bridge of the Dali...2/ The 1st 'event' leading up to the collision that the NTSB notes in its timeline is 1:24:59—when alarms on the bridge indicate power failure.
The ship was without electricity, engine power, lights, navigation, radio.
Dali was dark, literally & in terms of communications.

Sam Bankman Fried sentenced to 25 years in federal prison for the FTX crypto fraud.
Below from @WSJ — a great chart comparing him to other major white collar criminals.
SBF gets a decade more than Jeff Skilling from Enron. Twice as long as Elizabeth Holmes. 2/ Here's the WSJ account of this morning's sentencing hearing.
US Dist Judge Lewis Kaplan said he thought SBF was a risk to commit future fraud if freed; didn't seem to tell the truth on the stand; and lacked 'any real remorse.'
I was nudged to wear a pink pullover to go see Barbie yesterday evening.
Barbie was a great movie — remarkable balance of camp, satire, serious & storytelling.
Really hard to pull all that off. The actual movie-making—set design, costumes, directing—is artful & absorbing.
—>
2/ Fun movie-making, fun movie-watching, just provocative enough.
Half the people streaming into our DC-area theater were wearing pink. You could spot Barbie moviegoers 3 blocks away.
That was cool. A brief burst of community. 'They're going to Barbie too!'
And…a mystery!

James Cameron is being interviewed by Anderson Cooper on CNN now...
'It certainly wasn't a surprise today.'
The submersible apparently dropped some ballast weights, Cameron says, in effort to abort dive.
He says pilot must have heard hull starting to delaminate & took action.
2/ Cameron on the carbon composite material as the hull of the submersible:
'It's completely inappropriate for this use.'
Wow. Says carbon composite is wrong material for 'external pressure' vessels — ie, subs — v. internal pressure vessels, like scuba tanks.

US Navy heard Titan submersible implode in real time Sunday morning, using its wide network of advanced undersea listening technology.
…Huge @WSJ scoop.
Story says Navy heard implosion & notified Coast Guard commander managing the search.
Open story… wsj.com/articles/u-s-n…2/ Lots of people have asked exactly this question on Twitter:
Did the US Defense Department perhaps hear the Titan implode?
US Navy is always listening — with worldwide net of acoustic devices, and also using technology aboard nuclear subs.
So… —>

Coast Guard is able to offer a lot of detail on the implosion of the Titanic submersible.
• The ROV found two debris fields, and searchers identified 5 specific pieces of the submersible Titan — including both the front and rear curved ends of the pressure vessel
—>
2/ From CG briefing on the catastrophic loss of Titan vessel…
• The ROV that found Titan was the 1st one in water, looking around the Titanic wreckage
• It appears Titan imploded in the water column above Titanic — not caused by striking Titanic itself, for instance

The big takeaways from the Coast Guard briefing on the intense search for the missing Titan submersible:
• Noises were heard more than once, including today, & by more than one search plane.
• US Navy underwater experts are analyzing the noises—but no insights were offered.
2/ Indeed, CG Capt. Jamie Frederick & a Woods Hole official were at pains to point out that the search ships make noises, other ships make noises, sea creatures make noises — and offered no sense what the noises might mean, except that they'd be told the sounded like 'banging.'

It's Tax Day — a little late because of the Empancipation Day Holiday in Wash DC!
Here's some US tax tidbits to brighten filing day:
• 90% of Americans file their individual returns on time, on April 15. Just 10% request the automatic extension to Oct. 15.
—>
2/ (I'm impressed with that timeliness, given we are often a national of procrastinators...)
• 90% of Americans do not actually 'do' their own taxes — they either use a professional or use one of the semi-automated online services.
(A real indictment of US tax complexity.)

Huge moment in spaceflight this morning from SpaceX & Elon Musk.
SpaceX set to test launch huge Starship spaceship & Super Heavy rocket.
If successful—it has 33 huge engines running at launch—this would be a milestone.
T-minus 10 minutes. Watch here: spacex.com/launches/missi…2/ Starship is a marvel, once it starts flying.
It does 2 things NASA never has:
• It will be totally resuable — the upper cargo / passenger stage; the lower 'super heavy' rocket launch vehicle. Both fly back to Earth & land.
From inside the US air travel collapse of Southwest Airlines at Christmas 2022:
This airline is over. There's a single commitment of the US airline industry: We'll get you where we said, on the day we said, safely.
No one goes to Christmas, or a wedding, 'with flexibility.'
—>
2/ If you're re-booked for the big event, or the 5 day vacation, 4 days later — that's not transportation.
It's like sitting down at a great restaurant, ordering dinner, & having them tell you they can't do it — but they'll bring you exactly that food in 2 days. As breakfast.

Whoa!
Minute 35, Hannity cuts away from Trump speech.
‘We’ll get back to him for a very important ending.’
Too boring even for Hannity…?
2/ Mike Huckabee: ‘The approach of this speech was perfect. If he keeps on like this through 2024, he’s unbeatable.’
Hannity now alluding to something called ‘the failure in Ukraine.’
The only failure there is… yeah. Never mind.

Today's the day the world officially reaches 8 billion people.
Those people have the talent, energy, and spirit to solve our problems.
But the talent doesn't just come from Silicon Valley, or Austin, or Manhattan.
Just as likely from places pressed by water & food scarcity.
2/ The better a job we do taking care of everyone, the more likely all of us will thrive.
How has world population grown?

WMT CEO Doug McMillon says in earnings call:
Walmart has set prices of Thanksgiving dinner items the same as a year ago — 'including turkeys for less than $1 a pound.'
Sam's has lowered the prices of rack of lamb and lobster tails (I think the figure was 40%...)
2/ WMT's Sam's Club *lowers* the price on its hot dog combo meal — hot dog + a drink.
Was $1.50. Now $1.38.
McMillon delivers this news with straight face. Small humorous competitive shot at…Costco's famous hot dog.

A fascinating & unsettling story of how soaring bike thefts in Burlington — unsolved by police — have revealed some deeper problems in the city.
No neat ending to this one.
But we should ask police to be creative tackling ‘small’ or routine crimes.
—> nytimes.com/2022/11/12/bus…2/ A few years ago my wife’s car was stolen here in DC — right from the downtown garage where it was parked.
DC police were polite & utterly uninterested & unhelpful.
Turns out DC like many big cities is sprinkled w high tech license plate readers.
DC police could see the car!

It's been an impressive morning in the US economy. A thread of tidbits.
Southwest Air reports all-time record passengers, all-time record revenue.
CEO tells CNBC if they had the pilots they need, traffic could have been 5% to 8% higher.
'Our training faciliites are full.'
2/ McDonalds has a big quarter.
Comparable restaurant sales up 9.5% worldwide.
US comparable restaurant sales up 6.1%.
McD's said US 'visits' increased (including delivery orders). Said US restuarants increased prices 10%. Saw no weakness in US consumers.

We think of the incredibly increasing power of computer chips & their plummeting price as modern.
Price of 1 advanced integrated circuit:
1960: $1,000
1962: $100
1963: $15
1965: $7.28
From 1960 to 1965, price dropped 99.3% — while power doubled & doubled again.
Then?
—>
2/ …Price of 1 advanced integrated circuit:
1969: $1.58
1969 chip was 100 times more capable than 1960 chip.
Lighter. Smaller.
10,000 times more reliable.
…at 0.16% the cost.
How do we know all this?
The major customer was NASA & MIT — to build Apollo computers.

Twitter's former head of security says the company's management is chaotic & its security is flawed & inadequate.
Twitter doesn't have the systems or culture to protect Twitter users (it has our phone numbers & emails), or the company itself.
Bombshell. washingtonpost.com/technology/int…2/ This @washingtonpost story starts with back & forth — allegations from official whistleblower Peiter Zatko, the hacker known was 'Mudge,' and Twitter officials.
But as you read on, Twitter's defense of itself fades and Zatko's allegations gather force.

BREAKING GOOD NEWS…
Inflation cools. Consumer Price Index (CPI) lower than expected, & than last few months.
Year over year: +8.5%
expected: +8.7%
June: +9.1%
Core (exclu food & energy): +5.9%
expected: +6.1%
Month over month: +0.0%
…with gas prices still dropping.
2/ It's possible June 22 was 'peak inflation.'
Inflation still high. Rents up. Wages up 5.1% — not keeping up w/ prices in the last year.
Inflation is a real phenomenon — shortages, oil prices.
