This is how Navy SEALs swim out of a submerged submarine

We saw a compartment on the USS John Warner called a "lockout trunk." Lockout trunks are used as an escape hatch for the crew and to get SEALs off the ship.

During our recent tour of the USS John Warner nuclear-powered submarine, we got a chance to see a small compartment known as a "lockout trunk."

"This is actually how we would get SEALs off the ship submerged," Senior Chief Mark Eichenlaub told Business Insider.

"So you would stick a platoon of SEALs in here, 14 guys ... you fill this chamber with water until you match the outer sea pressure. Once the pressure in and outside the ship match, the hatch will lift off open, and they can swim out of a fully filled chamber into open ocean."

No one used to call Okta’s CEO before trying to squash his business — now Amazon and Google give him a heads-up and that's ‘progress’

What does it feel like when all four of the largest cloud providers decide they want to compete with you? Okta Todd McKinnon says when you are tiny, they ignore you. When you are bigger, you get a courtesy call first.

In some ways, the tech industry is like a small town, where everyone who's anyone knows each other and, sometimes, schemes behind each others' backs.

Todd McKinnon, CEO of Okta and former head of engineering for Salesforce working directly for Salesforce CEO Marc Benioff, is one of the people in that "in" crowd. And, as the years have gone by, he's been on the receiving end of much scheming.

The company that he cofounded, Okta, offers a cloud service that manages passwords and logins to other cloud services for corporate employees (known as "single sign on").

Okta had a successful IPO earlier this year and knocked it out of the park with

Trump suggests reporter be fired over inaccurate crowd size tweet he already apologized for

President Donald Trump on Saturday suggested a Washington Post reporter be fired over a misleading tweet. Trump accused the reporter of publishing "FAKE NEWS" and demanded an apology. Reporter Dave Weigel apologized immediately and noted he had already deleted the tweet.

President Donald Trump singled out a Washington Post reporter for repeated criticism Saturday evening, suggesting he be fired even after the reporter apologized for tweeting a misleading photo he had already deleted.

The reporter, Dave Weigel, had posted a photo of a near-empty stadium with the caption "Packed to the rafters," inaccurately suggesting it was taken during Trump's Florida rally on Friday. In fact, the photo was taken before the rally began.

"@DaveWeigel @WashingtonPost put out a phony photo of an empty arena hours before I arrived @ the venue, w/ thousands of people outside, on their way in,"

The Manhattan club counts bigwigs from the city's major industries as members, including NFL Commissioner Roger Goodell, billionaire fashion entrepreneur J. Christopher Burch, former White House communications director Anthony Scaramucci, and Blackstone Group CEO Stephen Schwarzman.

But don't mistake it for the stuffy Upper East Side clubs that have defined New York City's 1% for more than a century, founder Jennie Enterprise told Business Insider. CORE: Club seeks to be "the anticlub."

We recently spent the day at CORE to see what it's all about.

CORE: Club is located in midtown Manhattan, a short walk from Fifth Avenue, Grand Central, Rockefeller Center, and dozens of corporate HQs. A perfect location for the 1% who form the club's core membership. The entrance is tucked into a bui...

Decades after World War II and the Cold War, the world is agonizing over nuclear threats from North Korea.

The country recently tested its most powerful intercontinental ballistic missile to date, which leader Kim Jong Un claims can reach the United States. North Korea's foreign ministry also said on Wednesday that war on the Korean peninsula is "inevitable."
