Why do planes have door plugs? And other questions about the Alaska Airlines blowout, answered
The landing gear was stowed, the plane was climbing to cruising altitude, and then a segment of the wall exploded out of the rear cabin of Alaska Airlines Flight 1282 on Friday night, just 20 minutes after the plane took off from Oregon’s Portland International Airport airport en route to Ontario, Calif.
No passengers were seriously injured in the incident, which occurred as the Boeing 737-9 Max was 16,000 feet off the ground, and the pilots managed to safely land it back at the Portland airport shortly after.
The event has raised a number of questions. The most crucial is just how this kind of failure, in which a door plug installed to replace an emergency exit was ejected out of the side of the pressurized cabin, could occur in a commercial plane. Federal regulators at the National Transportation Safety Board are actively investigating the incident but have not yet announced any findings.
But what exactly is a door plug in the first place? How did the cockpit voice recording end up being erased before anyone could listen to it? The Boeing 737-9 Max has been grounded worldwide pending the results of the investigation, but how can you figure out what plane your flight is going to be on in the future? And how exactly did an iPhone that got sucked out the gaping hole in the plane survive the fall to Earth?
These questions, at least, can be answered.
What is a door plug? Do a lot of planes have them?
The part of the plane fuselage that failed Friday was called a door plug and is not unique to the 737-9 Max or other Boeing planes.
The number of required emergency exits changes based on the number of passengers a plane can hold. The original design of the 737-9 Max had two additional emergency exits toward the rear of the plane, in addition to the exits over the wings, at the rear, and near the cockpit. Some international customers of the 737-9 Max have been flying the planes at maximum capacity, which requires all the original emergency exits in place.
Alaska Airlines opted to fly its 737-9 Maxes with fewer passengers, which meant it didn’t need those additional emergency doors.
Robert Ditchey, an aviation expert and former airline executive, explained the logic behind replacing the doors with a plug.
“One would think the more the merrier” when it comes to emergency exits, Ditchey said, but exit doors with embedded slides or life rafts add weight to a plane and cost extra to maintain over the life of the craft.
After the airline ordered the modified plane, the company that manufactures its fuselage, Spirit AeroSystems in Wichita, Kan., took out the original door and added the door plug in. That modified fuselage was shipped to Boeing “fitted but not completed,” according to Reuters, which allows Boeing to remove the plug and use the hole in the side to access the cabin of the plane, in order to install interior components. Boeing ultimately reattached the door plug in its facility, then delivered the craft to Alaska Airlines.
Why would a door plug just fly off like that?
The NTSB has yet to determine the specific cause of the failure, but one possible culprit is some flaw in the bolts that were holding the door plug onto the rest of the airframe. On Monday, United Airlines announced that it had found loose bolts and other installation issues on the door plugs of its own 737-9 Max planes.
“We don’t know what failed,” Ditchey said, mentioning the possibility that some bolts could have been missing, the wrong size, improperly tightened, or could have mechanical flaws in the metal. He added that there could have been a structural failure in the frame of the craft, but said that he thinks that less likely.
In his view, this points to a design flaw in the door plug itself. The doors in a commercial plane are designed specifically to be un-openable while the cabin is pressurized, and designed to withstand the pressure of the cabin. Even without bolts or a latch holding it in place, a passenger would not be able to open the emergency exit on a plane that was fully pressurized. To ensure that they can’t blow out, like the door plug on the Alaska flight, they are built like wedges: larger on the inside than the outside, so the cabin pressure fits them snugly into place.
“The plug is in my opinion a bad design, because it can blow out and did blow out in this case,” Ditchey said, since it appears to have been bolted on from the outside, rather than wedged against the frame from within. “That troubles me greatly.”
Boeing and Spirit AeroSystems said that they could not comment on the specifics of the door plug assembly given the ongoing NTSB investigation into the failure.
Accidents over the last half a century in which the airplane cabin depressurized have been mostly attributable to baggage hold door failure, particularly with the now-obsolete DC-10 airliner, and fuselage metal fatigue, rather than failures in the main cabin doors.
What’s the deal with the flight recorder?
When Jennifer Homendy, chair of the NTSB, spoke about Friday’s incident at a news conference over the weekend, she brought up a very specific frustration: The cockpit voice recorder in the plane had automatically erased the recording from the incident.
Nobody turned the recorder off for safekeeping, and they are programmed to retain only the most recent two hours of audio, which is then automatically overwritten. As The Times reported:
Homendy was visibly exasperated by the loss of the black box recording. She noted that it was a “very chaotic event” when the plane landed and officials set up an emergency operations center.
“The maintenance team went out to get [the cockpit voice recorder], but it was right at about the two-hour mark,” she said, later adding: “We have nothing.”
The two-hour setup of the recorders strictly follows FAA guidelines, but proposed rules would extend the recording time to 25 hours, in line with current European regulations.
How can I tell what kind of plane I’m about to get on for my next flight?
Most airlines show the type of plane that you’ll be flying in when you view the flight information on their booking site. Third-party websites such as FlightAware and FlightStats also show the model of plane being used for a given flight.
Airlines that have purchased the relatively new 737-9 Max have grounded the plane for the time being, though, so there’s no risk of getting on a similar model to the plane in Friday’s incident. The earlier version of the 737 Max, the 737-8, is in wide use in airline fleets around the world but has a notable blemish on its safety history — those planes were grounded in 2019 after two deadly crashes that killed 346 people, but they were deemed safe to fly in 2021 and have been in heavy use since.
How the heck did an iPhone survive the fall from 16,000 feet?
As Sean Bates took a walk around his home on Sunday, he stumbled upon a remarkable artifact of Friday’s accident: the iPhone of a passenger that had been sucked out the hole in the plane.
The phone appears to have been found in the grass, which made for a soft landing, but still: three miles is a pretty long way to fall.
Luckily, a little physics provides the answer. All objects have a certain terminal velocity that they reach when falling through the air, based on how their size and weight interact with wind resistance. Small, heavy objects reach a higher terminal velocity than big, lightweight ones — think a baseball versus a piece of paper.
As Wired calculated in an article in 2011 after another incident of an iPhone surviving a fall from the skies, the small weight of the handset means that its speed when falling maxes out at between 27 and 95 mph, depending on whether it’s tumbling, falling flat or falling edge-down. As anyone with an iPhone can attest, even a much shorter drop can be fatal for the phones when the target is a concrete sidewalk, but with spongy grass serving as a shock absorber, the iPhone (apparently) just didn’t pick up enough speed to be smashed to smithereens. It can’t hurt that the unlucky passenger had their phone in a protective case.
What happened to the door plug?
At Sunday’s news conference, NTSB Chair Homendy said that the agency had recovered the chunk of airplane from the backyard of a home in Portland, Ore., after the agency was notified by a schoolteacher named Bob.
“Thank you, Bob,” Homendy said. The agency later posted a photo of the debris on its Twitter account.

After Warner Bros. merger, changes are coming to the historic Paramount lot. Here’s what to expect
With Paramount Skydance’s acquisition of Warner Bros. expected to saddle the combined company with $79 billion in debt, Paramount executives are looking to do away with redundant assets including real estate — and there is a lot of that.
Chief in the public’s imagination are their historic studios in Burbank and Hollywood, where legendary films and television show have been made for generations and continue to operate year-round.
“Both of these studios are in the core [30-mile zone,] the inner circle of where Hollywood talent wants to be,” entertainment property broker Nicole Mihalka of CBRE said. “It’s very prime real estate.”
When Sony and Apollo were bidding for Paramount in early 2024, their plan was to sell the Paramount property, but there is no indication that Paramount would part with its namesake lot.
For now, Paramount’s plan is to keep both studios operating with each studio releasing about 15 films a year, but the goal is to eventually consolidate most of the studio operations around the Warner Bros. lot in Burbank in order to to eliminate redundancies with the Paramount lot on Melrose Avenue, people close to Chief Executive David Ellison said.

Paramount would not look to raze its celebrated studio lot — the oldest operating film studio in Los Angeles — because of various restrictions on historic buildings there. Paramount also has a relatively new post-production facility on site and will likely need to the studio space.
Instead, the plan would be to lease out space for film productions, including those from combined Paramount-HBO streaming operations. Ellison also is considering plans to develop other parts of the 65-acre site for possible retail use, as well as renting space for commercial offices.
The studios’ combined property holdings are vast, and real estate data provider CoStar estimates they have about 12 million square feet of overlapping uses, including their studio campuses, offices and long-term leases in such film centers as Burbank, Hollywood and New York.
Century-old Paramount Pictures Studios is awash in Hollywood history — think Gloria Swanson as Norma Desmond desperately trying to enter its famous gate in “Sunset Boulevard,” and other classics such as “The Godfather,” “Titanic” and “Breakfast at Tiffany’s.”
The lot, however, is a congested warren of stages, offices, trailers and support facilities such as woodworking mills that date to the early 20th century. The layout is byzantine in part because Paramount bought the former rival RKO studio lot from Desilu Productions to create the lot known today.
Warner Bros. occupies 11 million square feet and owns 14 properties totaling 9.5 million square feet, largely in the United States and United Kingdom, CoStar said. About 3 million square feet of that commercial property is in the Los Angeles area.
The firm’s portfolio also includes the sprawling Warner Bros. Studios Leavesden complex in the U.K. and Turner Broadcasting System headquarters in Atlanta.
Paramount Skydance occupies 8 million square feet and owns 14 properties totaling 2.1 million square feet, according to CoStar. In addition to its Hollywood campus, Paramount’s holdings include prominent buildings in New York such as the Ed Sullivan Theater and CBS Broadcast Center.
Warner Bros. operates a 3-million-square-foot lot in Burbank with more than 30 soundstages — along with space for building sets and backlot areas — where famous movies including “Casablanca” and television shows such as “Friends” were filmed. Paramount’s 1.2-million-square-foot Melrose campus anchors a broader network of owned and leased production space, CoStar said.
Paramount’s lot is already cleared for more development. More than a decade ago, Paramount secured city approval to add 1.4 million square feet to its headquarters and some adjacent properties owned by the company.
The redevelopment plan, valued at $700 million in 2016, underwent years of environmental review and public outreach with neighbors and local business owners.
The plan would allow for construction of up to 1.9 million square feet of new stage, production office, support, office, and retail uses, and the removal of up to 537,600 square feet of existing stage, production office, support, office, and retail uses, for a net increase of nearly 1.4 million square feet.
The proposal preserves elements of the past by focusing future development on specific portions of the lot along Melrose and limited areas in the production core, architecture firm Rios said.
The Warner Bros. and Paramount lots “are two of the most prime pieces of real estate in the country,” Mihalka said. “These are legacy assets with a lot of potential to be [tourist] attractions in addition to working studios.”
Hollywood is still reeling from previous mergers, in addition to a sharp pullback in film and television production locally as filmmakers chase tax credits offered overseas and in other states, including New York and New Jersey.
Last year, lawmakers boosted the annual amount allocated to the state’s film and TV tax credit program and expanded the criteria for eligible projects in an attempt to lure production back to California. So far, more than 100 film and TV projects have been awarded tax credits under the revamped program.
The benefits have been slow to materialize, but Mihalka predicts that the tax credits and desirability of working close to home will lead to more studio use in the Los Angeles area, including at Warner Bros. and Paramount.
“These are such prime locations that we’ll see show runners and talent push back on having shows located out of state and insist on being here,” she said. “I think you’re going to see more positive movement here.”

How our AI bots are ignoring their programming and giving hackers superpowers
Welcome to the age of AI hacking, in which the right prompts make amateurs into master hackers.
A group of cybercriminals recently used off-the-shelf artificial intelligence chatbots to steal data on nearly 200 million taxpayers. The bots provided the code and ready-to-execute plans to bypass firewalls.
Although they were explicitly programmed to refuse to help hackers, the bots were duped into abetting the cybercrime.
According to a recent report from Israeli cybersecurity firm Gambit Security, hackers last month used Claude, the chatbot from Anthropic, to steal 150 gigabytes of data from Mexican government agencies.
Claude initially refused to cooperate with the hacking attempts and even denied requests to cover the hackers’ digital tracks, the experts who discovered the breach said. The group pummelled the bot with more than 1,000 prompts to bypass the safeguards and convince Claude they were allowed to test the system for vulnerabilities.
AI companies have been trying to create unbreakable chains on their AI models to restrain them from helping do things such as generating child sexual content or aiding in sourcing and creating weapons. They hire entire teams to try to break their own chatbots before someone else does.
But in this case, hackers continuously prompted Claude in creative ways and were able to “jailbreak” the chatbot to assist them. When they encountered problems with Claude, the hackers used OpenAI’s ChatGPT for data analysis and to learn which credentials were required to move through the system undetected.
The group used AI to find and exploit vulnerabilities, bypass defences, create backdoors and analyze data along the way to gain control of the systems before they stole 195 million identities from nine Mexican government systems, including tax records, vehicle registration as well as birth and property details.
AI “doesn’t sleep,” Curtis Simpson, chief executive of Gambit Security, said in a blog post. “It collapses the cost of sophistication to near zero.”
“No amount of prevention investment would have made this attack impossible,” he said.
Anthropic did not respond to a request for comment. It told Bloomberg that it had banned the accounts involved and disrupted their activity after an investigation.
OpenAI said it is aware of the attack campaign carried out using Anthropic’s models against the Mexican government agencies.
“We also identified other attempts by the adversary to use our models for activities that violate our usage policies; our models refused to comply with these attempts,” an OpenAI spokesperson said in a statement. “We have banned the accounts used by this adversary and value the outreach from Gambit Security.”
Instances of generative AI-assisted hacking are on the rise, and the threat of cyberattacks from bots acting on their own is no longer science fiction. With AI doing their bidding, novices can cause damage in moments, while experienced hackers can launch many more sophisticated attacks with much less effort.
Earlier this year, Amazon discovered that a low-skilled hacker used commercially available AI to breach 600 firewalls. Another took control of thousands of DJI robot vacuums with help from Claude, and was able to access live video feed, audio and floor plans of strangers.
“The kinds of things we’re seeing today are only the early signs of the kinds of things that AIs will be able to do in a few years,” said Nikola Jurkovic, an expert working on reducing risks from advanced AI. “So we need to urgently prepare.”
Late last year, Anthropic warned that society has reached an “inflection point” in AI use in cybersecurity after disrupting what the company said was a Chinese state-sponsored espionage campaign that used Claude to infiltrate 30 global targets, including financial institutions and government agencies.
Generative AI also has been used to extort companies, create realistic online profiles by North Korean operatives to secure jobs in U.S. Fortune 500 companies, run romance scams and operate a network of Russian propaganda accounts.
Over the last few years, AI models have gone from being able to manage tasks lasting only a few seconds to today’s AI agents working autonomously for many hours. AI’s capability to complete long tasks is doubling every seven months.
“We just don’t actually know what is the upper limit of AI’s capability, because no one’s made benchmarks that are difficult enough so the AI can’t do them,” said Jurkovic, who works at METR, a nonprofit that measures AI system capabilities to cause catastrophic harm to society.
So far, the most common use of AI for hacking has been social engineering. Large language models are used to write convincing emails to dupe people out of their money, causing an eight-fold increase in complaints from older Americans as they lost $4.9 billion in online fraud in 2025.
“The messages used to elicit a click from the target can now be generated on a per-user basis more efficiently and with fewer tell-tale signs of phishing,” such as grammatical and spelling errors, said Cliff Neuman, an associate professor of computer science at USC.
AI companies have been responding using AI to detect attacks, audit code and patch vulnerabilities.
“Ultimately, the big imbalance stems from the need of the good-actors to be secure all the time, and of the bad-actors to be right only once,” Neuman said.
The stakes around AI are rising as it infiltrates every aspect of the economy. Many are concerned that there is insufficient understanding of how to ensure it cannot be misused by bad actors or nudged to go rogue.
Even those at the top of the industry have warned users about the potential misuse of AI.
Dario Amodei, the CEO of Anthropic, has long advocated that the AI systems being built are unpredictable and difficult to control. These AIs have shown behaviors as varied as deception and blackmail, to scheming and cheating by hacking software.
Still, major AI companies — OpenAI, Anthropic, xAI, and Google — signed contracts with the U.S. government to use their AIs in military operations.
This last week, the Pentagon directed federal agencies to phase out Claude after the company refused to back down on its demand that it wouldn’t allow its AI to be used for mass domestic surveillance and fully autonomous weapons.
“The AI systems of today are nowhere near reliable enough to make fully autonomous weapons,” Amodei told CBS News.

iPic movie theater chain files for bankruptcy
The iPic dine-in movie theater chain has filed for Chapter 11 bankruptcy protection and intends to pursue a sale of its assets, citing the difficult post-pandemic theatrical market.
The Boca Raton, Fla.-based company has 13 locations across the U.S., including in Pasadena and Westwood, according to a Feb. 25 filing in U.S. Bankruptcy Court in the Southern District of Florida, West Palm Beach division.
As part of the bankruptcy process, the Pasadena and Westwood theaters will be permanently closed, according to WARN Act notices filed with the state of California’s Employment Development Department.
The company came to its conclusion after “exploring a range of possible alternatives,” iPic Chief Executive Patrick Quinn said in a statement.
“We are committed to continuing our business operations with minimal impact throughout the process and will endeavor to serve our customers with the high standard of care they have come to expect from us,” he said.
The company will keep its current management to maintain day-to-day operations while it goes through the bankruptcy process, iPic said in the statement. The last day of employment for workers in its Pasadena and Westwood locations is April 28, according to a state WARN Act notice. The chain has 1,300 full- and part-time employees, with 193 workers in California.
The theatrical business, including the exhibition industry, still has not recovered from the pandemic’s effect on consumer behavior. Last year, overall box office revenue in the U.S. and Canada totaled about $8.8 billion, up just 1.6% compared with 2024. Even more troubling is that industry revenue in 2025 was down 22.1% compared with pre-pandemic 2019’s totals.
IPic noted those trends in its bankruptcy filing, describing the changes in consumer behavior as “lasting” and blaming the rise of streaming for “fundamentally” altering the movie theater business.
“These industry shifts have directly reduced box office revenues and related ancillary revenues, including food and beverage sales,” the company stated in its bankruptcy filing.
IPic also attributed its decision to rising rents and labor costs.
The company estimated it owed about $141,000 in taxes and about $2.7 million in total unsecured claims. The company’s assets were valued at about $155.3 million, the majority of which coming from theater equipment and furniture. Its liabilities totaled $113.9 million.
The chain had previously filed for bankruptcy protection in 2019.
