Longtime Slashdot reader Mr_Blank shares a report from Autoblog: Once a new OTA update becomes available, owners of GM vehicles have 45 days to install the update. After this date, the company will not cover any damages or issues that are caused by ignoring the update. "Damage resulting from failure to install over-the-air software updates is not covered," states the warranty booklet for 2025 and 2026 models.

This same rule applies to all GM's brands in the USA: Chevrolet, Buick, Cadillac, and GMC. However, if the software update itself causes any component damage, that will be covered by the warranty. Owners coming from older GM vehicles will have to adapt as the company continues to implement its Global B electronic architecture on newer models, which relies heavily on OTA updates. Similar policies appear in the owner's manual for Tesla. Software-defined vehicles are here to stay, even if some of them have far more tech glitches than they should -- just ask Volvo.

Elon Musk's Boring Company plans to build a 10-mile underground transportation loop in Nashville connecting the airport to downtown, with private funding and a projected launch as early as fall 2026. "If that happens, Nashville would become the second city where The Boring Company has opened such a system, with the first being Las Vegas," notes TechCrunch. "The company has spent the last few years in Sin City digging and opening tunnels around the Las Vegas Convention Center, and claims to have given 3 million rides in Teslas to date." From the report: The project will be privately funded by The Boring Company "and its private partners," according to the Governor's press release, though those partners are not named. The Boring Company and local officials will now begin a "public process to evaluate potential routes, engage community stakeholders, and finalize plans for the project's initial 10-mile phase." Construction won't begin until the project clears the approvals process. But the governor's office said the first segment of the loop could be operational as "early as fall of 2026."

An anonymous reader shares an analysis: In most major aviation markets, including the U.S. and Europe, competition is an oligopolistic affair, with several large airlines competing for market share. India's domestic sector, however, is increasingly characterized by the ascent of a single airline.

Low-cost carrier IndiGo has achieved an extraordinary concentration of the market, capturing approximately 64.4% of all passenger traffic as of May. More strikingly, the airline operates with a near-monopoly on 66% of its domestic routes, facing little to no direct competition in a significant portion of its network.

This position is the culmination of a decade-long expansion that saw the exit of rivals like Jet Airways and GoAir. Today, its remaining competitors continue to struggle; SpiceJet's domestic market share has fallen to just 2% while it operates a reduced fleet of only 19 aircraft. Air India, despite its acquisition by the Tata Group in 2022, has been slow in its restructuring and continues to cede domestic ground, with the flag carrier remaining unprofitable.

The Airbus A380, the world's largest commercial passenger jet, faces mounting maintenance challenges as regulatory authorities issue an increasing number of safety directives. The European Union Aviation Safety Agency has listed 95 airworthiness directives for the A380 since January 2020, approximately double the number issued for large Boeing aircraft during the same period.

The directives address problems including leaking escape slides, cracked seals, and a ruptured landing-gear axle. A comprehensive maintenance check of the massive plane requires 60,000 hours of labor, according to aircraft repairer Lufthansa Technik. Airlines remain committed to operating the twin-deck aircraft due to limited large-capacity alternatives, with Boeing's 777X years behind schedule and Airbus unable to produce long-haul A350s quickly enough. British Airways plans to overhaul A380 cabins starting next year, while Emirates intends to keep flying the aircraft until the end of the next decade.

Tesla open its first diner/Supercharger station Monday in Los Angeles, reports CNBC — an always-open two-story restaurant serving "classic American comfort food" next to 80-charging stalls surrounded by two 66-foot megascreens "playing a rotation of short films, feature-length movies and Tesla videos."

Tesla described the restaurant's theme as "retro-futuristic". (Tesla's humanoid robot Optimus was outside filling bags of popcorn.) There's souvenier cups, the diner's food comes in Cybertruck-shaped boxes, and the owner of a Tesla Model Y told CNBC "It feels kind of like Disneyland, but for adults — or Tesla owners." (And yes, one of the choices is a "Tesla Burger.")

"Less than 24 hours after opening, the line at the Tesla Diner stretched down the block," notes CNBC's video report. (One customer told CNBC they'd waited for 90 minutes to get their order — but "If you're a Tesla owner, and you order from your car ahead of time, you don't have to wait in line.")

The report adds that Elon Musk "says if the diner goes well, he's looking to put them in major cities around the world."

American Airlines Chief Executive Robert Isom criticized the use of AI in setting air fares during an earnings call, calling the practice "inappropriate" and a "bait and switch" move that could trick travelers. Isom's comments target Delta Air Lines, which is testing AI to help set pricing on about 3% of its network today with plans to expand to 20% by year-end.

Delta maintains it is not using the technology to target customers with individualized offers based on personal information, stating all customers see identical fares across retail channels. US Senators Ruben Gallego, Richard Blumenthal, and Mark Warner have questioned Delta's AI pricing plans, citing data privacy concerns and potential fare increases. Southwest Airlines CEO Bob Jordan said his carrier also has no plans to use AI in revenue management or pricing decisions.

A new video shows flames emanating from one side of a Boeing 767 moments after takeoff, reports LiveMint.com. "Delta flight 446 was forced to make an emergency landing in Los Angeles," they report, adding "No one was injured. The fire was extinguished upon landing." According to a report by Aviation A2Z, the plane (24-year-old Boeing 767-400 with registration N836MH) had just departed from Los Angeles International Airport when its left engine ignited. The pilots promptly declared an emergency and requested to return to the airport.
Delta faced a similar issue less than three months ago. The article notes the engine of an Airbus also caught on fire in April when pushing back from the gate for departure. CBS News describes that incident: Delta said crew members evacuated the cabin when flames were seen in the tailpipe of one of the plane's two main engines and fire crews quickly responded. According to Delta, the plane, an Airbus 330, had 282 passengers, 10 flight attendants and two pilots on board...

The engine fire marks the latest aviation scare involving the airline in recent months. In February, 21 people were injured after a Delta plane flipped upside down while landing amid wintry conditions at Toronto Pearson International Airport. All of the injured passengers were later released from the hospital. In January, several people were injured after a Delta flight aborted its takeoff at Hartsfield-Jackson Atlanta International Airport, forcing about 200 passengers to evacuate the plane through emergency slides. ["A passenger says the engine on the Boeing 757 caught fire," according to CBS's video report in January.]

An anonymous reader shared this report from the Washington Post: Ships trigger seafloor methane emissions while moving through shallow water, researchers report in Communications Earth & Environment. The scientists say the unexpected discovery has nothing to do with the type of fuel used by the ship. Instead, "ship-induced pressure changes and turbulent mixing" trigger the release of the gas from the seafloor. Bubbles and gas diffusion push the methane into the atmosphere, where it acts as a greenhouse gas...

Container and cruise ships triggered the largest and most frequent methane emissions, but the study suggests that ships of all kinds, regardless of their type of engine or size, trigger methane emissions. Researchers said they observed emissions that were 20 times higher in the shipping lane than in undisturbed nearby areas. Given the number of ports in similarly shallow areas worldwide, it's important to learn more about emissions in shipping lanes and to better estimate their "hitherto unknown impact," study co-author Johan Mellqvist, a professor of optical remote sensing at Chalmers University of Technology in Sweden, said in a news release.

ABC News reports: Dialogue heard on a cockpit voice recording indicates that the captain of the Air India flight that crashed in June, killing 260 people, may have turned off the fuel just after takeoff, prompting the first officer to panic, according to The Wall Street Journal, which cited sources familiar with U.S. official's early assessment... The president of the Federation of Indian Pilots condemned the Wall Street Journal report, saying, "The preliminary report nowhere states that the pilots have moved the fuel control switches, and this has been corroborated by the CVR [cockpit voice recorder] recording."
But meanwhile "India on Monday ordered its airlines to examine fuel switches on several Boeing aircraft models," reports Reuters, "while South Korea ordered a similar measure on Tuesday, as scrutiny intensified of fuel switch locks at the centre of an investigation into a deadly Air India crash." The precautionary moves by the two countries and airlines in several others came despite the planemaker and the U.S. Federal Aviation Administration assuring airlines and regulators in recent days that the fuel switch locks on Boeing jets are safe... [The preliminary report] noted a 2018 advisory from the FAA, which recommended, but did not mandate, operators of several Boeing models, including the 787, to inspect the locking feature of fuel cutoff switches to ensure they could not be moved accidentally... Some airlines around the world told Reuters they had been checking relevant switches since 2018 in accordance with the FAA advisory, including Australia's Qantas Airways. Others said they had made additional or new checks since the release of the preliminary report into the Air India crash.
The web site of India's Financial Express newspaper spoke to Mary Schiavo, who was Inspector General of America's Transportation Department from 1990 to 1996 (and is also a long-time critic of the FAA). The site notes Schiavo "rejected the claims of human error that a pilot downed the Ahmedabad to London flight by cutting off the fuel supply." Schiavo exclusively told FinancialExpress.com that this is not the first time fuel switch transitioned from "Run" to "Cutoff" on its own. It happened five years ago, too. "There was an All Nippon Airways (ANA) flight in 2019 in which the 787 aircraft did this itself, while the flight was on final approach. No pilot input cutting off the fuel whatsoever," Schiavo told FinancialExpress.com... "The investigation revealed the plane software made the 787 think it was on the ground and the Thrust Control Malfunction Accommodation System cut the fuel to the engines," she told FinancialExpress.com, before adding, "The pilots never touched the fuel cutoff..." Both engines flamed out immediately after the pilot deployed the thrust reversers for landing. The aircraft, which was also a Boeing 787 Dreamliner, was towed away from the runway by the authorities, and no injuries were reported.

UK Civil Aviation Authority, four weeks before the crash, had warned about similar fuel system issues on Boeing aircraft [on May 15, 2025]. "The FAA has issued an Airworthiness Directive addressing a potential unsafe condition affecting fuel shutoff valves installed on Boeing aircraft," the UK regulator's notice read, listing the B737, B757, B767, B777 and B787...

Thrust Control Malfunction Accommodation informs FADEC [a digital computer] about whether the aircraft is on the ground or in the air, and if it believes the aircraft is on the ground, it may automatically throttle back the engines, without the pilot's input.
Reuters notes that the Air India crash preliminary report "said maintenance records showed that the throttle control module, which includes the fuel switches, was replaced in 2019 and 2023 on the plane involved in the crash."

Felix Baumgartner has died. He was 56.

In 2012 Slashdot extensively covered the skydiver's "leap from the edge of space." ABC News remembers it as a Red Bull-financed stunt that involved "diving 24 miles from the edge of space, in a plummet that reached a speed of more than 500 mph." Baumgartner recalled the legendary jump in the documentary, "Space Jump," and said, "I was the first human being outside of an aircraft breaking the speed of sound and the history books. Nobody remembers the second one...."

Baumgartner, also known as "Fearless Felix," accomplished many records in his career, including setting the world record for highest parachute jump atop the Petronas Towers in Malaysia, flying across the English Channel in a wingsuit in 2003, and base jumping from the 85-foot arm of the Christ the Redeemer statue in Brazil in 2007.
"Baumgartner's altitude record stood for two years," remembers the Los Angeles Times, "until Google executive Alan Eustace set new marks for the highest free-fall jump and greatest free-fall distance."

They report that Baumgartner died Thursday "while engaged in a far less intense activity, crashing into the side of a hotel swimming pool while paragliding in Porto Sant Elpidio, a town on central Italy's eastern coast." More details from the Associated Press: "It is a destiny that is very hard to comprehend for a man who has broke all kinds of records, who has been an icon of flight, and who traveled through space," Mayor Massimiliano Ciarpella told The Associated Press.Ciarpella said that Baumgartner had been in the area on vacation, and that investigators believed he may have fallen ill during the fatal flight... Baumgartner, a former Austrian military parachutist, made thousands of jumps from planes, bridges, skyscrapers and famed landmarks...
ABC News remembers that in 2022 Baumgartner wrote in Newsweek that "Since I was a little kid, I've always looked up to people who left a footprint on this planet... now I think I have left a footprint...

"I believe big dreamers always win."

An anonymous reader quotes a report from TechCrunch: California Forever announced on Thursday plans to build a massive manufacturing park called Solano Foundry, the newest addition to its master-planned "utopian" city backed by a group of Silicon Valley billionaires. Solano Foundry is 2,100 acres that can host 40 million square feet of advanced tech manufacturing space. The manufacturing park will be built as part of its planned walkable city with over 175,000 homes, CEO Jan Sramek said at the Reindustrialize conference in Detroit.

Sramek tweeted that U.S. manufacturers can't win by "building factories off of random freeway exits in the middle of nowhere. The best people don't want to work there." This site will offer expedited permitting, transportation for finished goods, and plenty of power from renewable energy, he said. The hope is that it will attract hardware, engineering, and AI talent from relatively nearby Silicon Valley. Solano County is about 40 miles northeast of San Francisco.

Uber said Thursday it will partner with electric vehicle maker Lucid Group and autonomous driving startup Nuro to deploy robotaxis using Lucid Gravity SUVs equipped with Nuro Driver technology on its ride-sharing network. The companies plan to launch the first vehicles in late 2026 in an unidentified major US city and deploy at least 20,000 robotaxis over six years.

Uber will make multi-hundred-million dollar investments in both partners, including $300 million for Lucid to upgrade its assembly line for integrating Nuro hardware into Gravity vehicles.

An anonymous reader quotes a report from Ars Technica: For some years now, detractors of battery electric vehicles have held up hydrogen as a clean fuel panacea. That sometimes refers to hydrogen combustion engines, but more often, it's hydrogen fuel cell electric vehicles, or FCEVs. Both promise motoring with only water emitted from the vehicles' exhausts. It's just that hydrogen actually kinda sucks as a fuel, and automaker Stellantis announced today that it is ending the development of its light-, medium- and heavy-duty FCEVs, which were meant to go into production later this year.

Hydrogen's main selling point is that it's faster to fill a tank with the stuff than it is to recharge a lithium-ion battery. So it's a seductive alternative that suggests a driver can keep all the convenience of their gasoline engine with none of the climate change-causing side effects. But in reality, that's pretty far from true. [...] Between the high development costs and the fact that FCEVs only sell with strong incentives, the decision was made to cancel the production of hydrogen vans in France and Poland. Stellantis says there will be no job losses at its factories and that R&D staff will be put to work on other projects. "In a context where the Company is mobilizing to respond to demanding CO2 regulations in Europe, Stellantis has decided to discontinue its hydrogen fuel cell technology development program," said Jean-Philippe Imparato, chief operating officer for Enlarged Europe. "The hydrogen market remains a niche segment, with no prospects of mid-term economic sustainability. We must make clear and responsible choices to ensure our competitiveness and meet the expectations of our customers with our electric and hybrid passenger and light commercial vehicles offensive."

The U.S. Department of Defense has awarded contracts worth up to $200 million each to OpenAI, Google, Anthropic, and xAI to scale adoption of advanced AI. "The contracts will enable the DoD to develop agentic AI workflows and use them to address critical national security challenges," reports Reuters, citing the department's Chief Digital and Artificial Intelligence Office. From the report: Separately on Monday, xAI announced a suite of its products called "Grok for Government", making its advanced AI models -- including its latest flagship Grok 4 -- available to federal, local, state and national security customers. The Pentagon announced last month that OpenAI was awarded a $200 million contract, saying the ChatGPT maker would "develop prototype frontier AI capabilities to address critical national security challenges in both warfighting and enterprise domains."

The contracts announced on Monday deepen the ties between companies leading the AI race and U.S. government operations, while addressing concerns around the need for competitive contracts for AI use in federal agencies. "The adoption of AI is transforming the (DoD's) ability to support our warfighters and maintain strategic advantage over our adversaries," Chief Digital and AI Officer Doug Matty said.

Air India's chief executive urged staff to avoid drawing premature conclusions about what caused one of the airline's Boeing triangle jets to crash last month, after a preliminary investigation ruled out mechanical or maintenance issues, turning attention to the pilots' actions. WSJ: Campbell Wilson told staff that the probe into the crash was "far from over," according to an internal memo, reviewed by The Wall Street Journal, in which he set out some of the findings of a report issued by India's Aircraft Accident Investigation Bureau at the end of last week.

Wilson's memo didn't mention one of the AAIB's findings: that the airplane's fuel-control switches had been turned off one by one, seconds after takeoff, starving both engines of fuel. The switches, which sit between the two seats in the cockpit, were turned back on about 10 seconds later, but the engines apparently couldn't fully restart and gain thrust fast enough, the report said.

The crash of the London-bound Boeing 787 Dreamliner killed all but one of the 242 passengers and crew on board, as well as 19 people on the ground, when the plane slammed into a residential area beyond the airport in the Indian city of Ahmedabad. In the memo, Wilson said "over the past 30 days, we've seen an ongoing cycle of theories, allegations, rumours and sensational headlines, many of which have later been disproven."

"In the battle for Ukraine, the front line is increasingly at a standstill" because of "rapid innovations in drone technology..." according to the Wall Street Journal. "Each side has hundreds of them constantly in the air across the 750-mile front line."

And drones "now bring everything from food and water to ammunition, power banks — and, in at least one case, a fire extinguisher — to the front, sparing soldiers trips through the most dangerous part of the battlefield where enemy drones might pick them off." Drones can lay mines, deliver everything from ammunition to medication and even evacuate wounded or dead soldiers. Crucially, drones spot any movement along the front line and are dispatched to strike enemy troops and vehicles. When Russia sent tank columns into Ukraine in February 2022, Ukraine needed to find out where they were headed — and fast. Enter the humble "wedding drone," available in stores for about $2,000 and repurposed to scan for enemy units rather than capture nuptial panoramas. Deployed by enthusiasts acting independently or attached to army units, the drones helped Ukrainian forces, which were vastly outnumbered and outgunned, to know exactly where to deploy to counter Russian arrowheads.

Surveillance drones quickly became a necessity rather than a luxury. Often provided by charity funds, they were used to scan enemy positions for equipment, stores and headquarters.... A cheap and simple tweak made the so-called wedding drones deadly. Tech buffs realized that a simple claw-like contraption, created using a 3-D printer, could be activated from the radio controller by turning on the drone's light, causing it to release a grenade. The explosion could wound or kill a soldier or even detonate an armored vehicle if dropped through its hatch. Over time, soldiers experimented with ways to add more explosives, for example by melting down explosives garnered from Soviet-era munitions and pouring them into new, lighter plastic casings.

No innovation has had a bigger impact on the war in Ukraine than first-person-view, or FPV, drones. With explosives strapped to them, FPVs fly directly into their targets, turning them into low-cost suicide bombers. Though FPVs don't deliver as much explosive punch as rockets, they are far more accurate — and the sheer volume that Ukraine has manufactured means they can be deployed to similar effect... Sitting in a bunker several miles behind the front, a drone pilot slips on FPV goggles to see the view from the drone's camera and fly it into an enemy position or asset. The Russians have since adopted FPVs en masse. Their abundance has played a central role in slowing down the movement of the front line. Anything within around 12 miles of the contact line can now become a target for FPVs. They are so cheap to make that both sides can expend them on any target — even a single infantryman.

Because they are so small and fast, FPVs are difficult to shoot down. The main defense against them has been electronic jamming systems, which disrupt the communication between the drone and the pilot. Though most drone innovations in the war have come from the Ukrainian side, the Russians pioneered the most important adaptation for FPV drones — the addition of a fiber-optic cable connecting the drone to the pilot that can overcome jamming.
Benjamin Franklin once predicted flying machines might "convince sovereigns of the folly of war... since it will be impracticable for the most potent of them to guard his dominions..."

Electrek reports on the new Omo X, a scooter planned for release in 2026 that's "full of premium tech features that blur the lines between e-scooter and self-driving EV." At its recent launch in Jakarta, the Omo X didn't just sit pretty center stage, it actually drove itself onto the stage using its "Halo Pilot" system, which apparently comes complete with adaptive cruise control, remote summon, self-parking, and even automatic reversing and self-balancing at low speeds. This is legit autonomous behavior previously reserved for cars, now shrunk down and smoothed out for a two-wheeler. Under the hood — or rather, behind the sleek bodywork — Omoway's Halo architecture delivers collision warning, emergency-brake assist, blind spot monitoring, and V2V [vehicle-to-vehicle] communication.

The frame is modular, too. It can be reconfigured in step-through, straddle, or touring posture to suit casual riders, commuters, and motorcycle wannabes alike. That kind of flexibility isn't just a marketing gimmick, but rather it looks purpose-built to capture diverse motorcycle-heavy markets like Indonesia, which counts over 120 million two-wheelers and is quickly transitioning to electric models... It's tech-rich, head-turning, and seems built to evolve with software updates. The remote summon and AI-assisted features could genuinely simplify urban mobility, and tricks like automatically driving itself to a charging station sound legitimately useful...

[But] Omoway's vision here will have to carry extra sensors, actuators, and redundant systems to support those smart functions. With added costs and complexity, will riders in developing markets pay a premium, carry extra maintenance risk, or worry about obsolescence? Much hinges on Omoway's software support and local service networks.
The article reports a projected price around €3,500 (roughly $3,800). "And while Indonesia may have been the launchpad, global markets aren't off the table..."

An anonymous reader shared this report from Jalopnik: On July 2, the 88th anniversary of famed aviator Amelia Earhart's disappearance, Purdue University announced an expedition [which will launch in November] to confirm whether or not the wreckage of her plane has been found.

Satellite imagery from a decade ago indicated the presence of something that sure looks plane-like under the waters of Nikumaroro Island, an uninhabited spit of land in the middle of the Pacific Ocean that just happens to be near Earhart's intended flightpath...

This isn't the first time Earhart investigators have been to Nikumaroro. Human bones were recovered from the island previously, which scientists determined with 99% confidence to belong to the beloved pilot, per the university's student newspaper the Purdue Exponent. The investigators also found some women's beauty products from the 1930s. If that is indeed where Earhart died, it stands to reason that her Lockheed Electra 10E, nicknamed the Flying Laboratory, wouldn't be far away. Since nobody noticed any aircraft wreckage on the island (which isn't very big), it would probably be under the water.

Recovering such a legendary airplane will be a multi-stage process spanning years. This expedition, which will embark in November, is only planning to verify what's actually there, not retrieve anything. Recent satellite imagery doesn't show the object anymore, meaning it might have become buried; in fact, it was only ever visible in 2015, right after a cyclone blew threw and shifted a bunch of sand, as NBC News reports. The team will start with non-invasive procedures, such as sonar and magnetometers, before drilling through the silt with a hydroglobe to make physical contact with the object. Lastly, they will use a suction dredge to pull off loose sediment. If they're lucky, that will be sufficient to actually see part of the Lockheed Electra.

Lucid Motors set a Guinness World Record for the longest journey by an electric car on a single charge, covering a distance of 749 miles (about 1,205 km), reports New Atlas. "In doing so, Lucid broke the 1,045-km (649-mile) record previously achieved by the Mercedes-Benz EQS450+ in June 2025 by the Japanese car website www.webcg.net/articles/-/52268webCG." The electric vehicle covered this journey between St. Moritz, Switzerland, and Munich, Germany, traveling through highways, secondary roads, and alpine roads — all without a single halt for charging. Given that the vehicle has a 960-km (596-mile) WLTP range, my guess is that the test team must have made good use of favorable road and weather conditions to make the feat possible. With a net elevation decrease of just over 1,310 m (about 4,300 ft) throughout the drive, the EV most certainly benefited from regenerative braking, a rather useful feature that turns downhill momentum back into battery power. Lucid has yet to release official data like average speed or total drive time, but what is apparent is that this was not a high-speed dash but rather a well-planned route to achieve one impressive result...

The Air Grand Touring has two all-wheel drive electric motors with a combined system output of 611 kW (819 horsepower) and 1,200 Nm (885 lb.ft) of torque. Power is provided by an NMC battery, which has a gross energy capacity of 117 kWh (112 kWh usable). Best of all, it can go from 0-60 mph in just three seconds flat... For reference, the almost half-priced BMW i4 and jazzy Porsche Taycan offer less than half the WLTP range of the Lucid Air GT. So, it's not like there's a head-to-head competition out there. Lucid is miles ahead in its class (pun intended!)

Starting at US$112,650, the Air Grand Touring is among the most luxurious sedans on the market right now. But as you can see, it comes at a price. Still, knowing that there is technology to conquer range anxiety is comforting. It might take a while, but there's no reason why we can't expect such range figures from reasonably priced EVs in the near future.

Slashdot reader hcs_$reboot shared this report from NPR: A pair of switches that control the fuel supply to the engines were set to "cutoff" moments before the crash of Air India Flight 171, according to a preliminary report from India's Air Accident Investigation Bureau released early Saturday in India... Indian investigators determined the jet was properly configured and lifted off normally. But three seconds after takeoff, the engines' fuel switches were cut off. It's not clear why.

According to the report, data from the flight recorders show that the two fuel control switches were switched from the "run" position to "cutoff" shortly after takeoff. In the cockpit voice recording, one of the pilots can be heard asking the other "why did he cutoff," the report says, while "the other pilot responded that he did not do so." Moments later, the report says, the fuel switches were returned to the "run" position. But by then, the plane had begun to lose thrust and altitude. Both the engines appeared to relight, according to investigators, but only one of them was able to begin generating thrust.

The report does not draw any further conclusions about why the switches were flipped, but it does suggest that investigators are focused on the actions of the plane's pilots. The report does not present any evidence of mechanical failures or of a possible bird strike, which could have incapacitated both engines at the same time.
