Long-time Slashdot reader necro81 writes: There are several companies, such as Tesla, trying to make semi trucks fully electric. The capital cost for such a truck, and the MW-scale infrastructure to recharge it, may be a hard sell for some operators. [IEEE Spectrum notes that's a charging infrastructure "that most freight corridors do not yet reliably provide."] But some companies are instead adding batteries and an electric motor to the semi-trailers that trucks haul behind them. "The Nivalis Powered Trailer Kit centers on an electric axle [rated at 50 kilowatts-peak]... capable of both propulsion assistance and regenerative braking. It draws on a 60-kilowatt-hour, 400-volt lithium-ion battery pack charged from three sources: the axle itself during braking and deceleration, a full-rooftop array of photovoltaic panels generating up to 3.7 kilowatts-peak, and a 32-amp, three-phase AC grid connection available during parking stops." This approach is more akin to a plug-in hybrid: the truck may still be diesel-powered, but the electric assist from the trailer allows the truck to run more efficiently. Replacing diesel with kWh can save operators money while also reducing emissions. This incremental approach may be more accessible and less capital-intensive than replacing the truck itself. From the article: The driver's only window into the system is a small display readable from the cab's side mirror that shows the system status and battery charge level. Nothing about the trailer's handling or licensing requirements changes. The partners project savings of up to 7,000 liters of diesel per trailer per year, which is enough to keep about 19 tonnes of carbon dioxide out of the air... Trailer Dynamics, an Aachen-based company, has conducted field tests with BMW Logistics, DB Schenker, Duvenbeck, and Volkswagen Konzernlogistik, reporting average fuel savings of around 40% for diesel tractor combinations, substantially higher than the up to 18% reduction implied by the Nivalis projection... Trailer Dynamics prices its system between €145,000 and €195,000 and targets a payback period of no more than five years. Nivalis targets five to six years at current costs.

NHTSA is ordering autonomous vehicle developers to explain by the end of the month how they will stop driverless cars from interfering with police, firefighters, and paramedics. TechCrunch reports: [NHTSA Administrator Jonathan Morrison] noted in the letter (PDF) that the agency has "identified a clear pattern of driverless AVs interfering with law enforcement and other first responders," citing instances in which these vehicles drove into active emergency scenes, blocked the paths of ambulances and firefighters, or failed to recognize and respond to basic safety conditions like flashing lights, flares, smoke, fire, and traffic cones. The agency has demanded that AV developers present their "solutions" to this problem by the end of the month. "Let me be clear: the inability to detect and appropriately respond to such situations represents a functional insufficiency," Morrison's letter reads. "Emergency scenes are not rare or extreme 'edge cases.' As such, NHTSA is today issuing a call to action for AV developers and operators to immediately focus their resources on fixing this issue." The agency doesn't explicitly call out any particular company in the letter; however, the details suggest it is directed at robotaxi operators like Waymo. [...] The agency's letter to AV developers doesn't say what the consequences would be if the request is ignored. Nor does it outline what the acceptable solutions would be. But the agency does imply it would hold companies accountable, just as it does human drivers who impede law enforcement. "Every second matters when law enforcement officers, firefighters, or paramedics are answering a call because lives are on the line," the letter states. "That is why human drivers who impede these operations are subject to fines and even jail time." The agency also noted in a press release accompanying the letter that it's making progress on updating Federal Motor Vehicle Safety Standards (FMVSS) requirements, which govern vehicle design and equipment requirements. These proposed changes could help autonomous vehicle companies like Tesla and Zoox, which are developing vehicles without steering wheels, pedals, or other features required on human-driven cars. The agency has already proposed rules that would eliminate the need for windshield wipers, sun visors, defogging systems, and tire placards. The agency released a new 2026 Regulatory Plan and Unified Agenda last week, outlining its proposals.

247,000 miles on an EV battery? So says the owner of a U.K.-based used-car sales company that specializes in Evs, who tells the Wall Street Journal EV batteries keep performing well even after several hundred thousand miles. "They are proving themselves to be exceptionally reliable." After five years on the road, the average EV will still be able to drive up to 95% of its original range, according to Recurrent, a data-science company that provides a battery-monitoring tool for EVs — better than many in the auto industry expected... Potential new car buyers' fear of having to pay for a battery replacement is the number one reason they choose to steer clear of EVs, according to a 2025 survey from industry research firm AutoPacific. When early EVs hit the market, buyers' concerns were well-founded. Roughly one in 12 EVs built from 2011 to 2016 have had to have battery replacements. But new data shows that more modern EVs are doing better so far. Among EVs built from 2022 on, 0.3% have had battery replacements, according to a 2025 study from Recurrent. As battery technology has advanced, EVs have avoided problems like the ones that plagued the original Nissan Leaf when it hit the market in 2010, for example. Those cars lacked the battery-cooling technology that is in newer EVs, and they made headlines for wearing down quickly. Buyer perception hasn't quite caught up, according to Scott Case, co-founder and chief executive of Recurrent... The newest battery-powered EVs have lifespans comparable to internal-combustion-engine vehicles, even when driven more miles, according to Viet Nguyen-Tien, a research officer at the London School of Economics who focuses on Evs. Improvements in car batteries' chemical contents, battery-management systems and thermal regulation have been the difference in making batteries last longer and cost less, Nguyen-Tien said. Battery prices have fallen more than 90% since 2010, according to a BloombergNEF report from late last year. Industry analysts say battery-replacement costs are also improving as more EVs are designed for repairability in the long-haul. An out-of-warranty battery replacement can cost anywhere from $5,000 to $16,000, depending on the manufacturer, according to Recurrent. But many EV manufacturers have shifted to allow smaller components of their battery packs to be repaired, which can allow owners to avoid the full costs of a battery replacement, Case said. EV batteries aren't without their challenges, though. A battery that is frequently fast-charged with high power loses its range, on average, at twice the rate of a battery charged at a lower power, according to telematics company Geotab. Frequently charging a battery to 100%, or letting it rest at 0% for extended periods, can also reduce range long-term. And EVs regularly deliver less range in extreme cold or heat. The article also includes two new projections on EV adoption: "The share of new EVs sold is expected to nearly double to 11% of new-car sales in the U.S. by 2030, according to industry consulting firm AlixPartners." "Globally, EVs already make up 15% of new-car sales and are expected to form nearly a quarter of the global market by 2030, according to AlixPartners."

The FAA plans to replace its 1973 ban on civilian supersonic flight over U.S. land with a noise-based standard, potentially allowing aircraft to exceed Mach 1 as long as they stay below certain sound limits. The agency aims to finalize the rules by mid-2027, opening the door for companies such as Boom Supersonic and Spike Aerospace to operate quieter next-generation passenger jets over land. Longtime Slashdot reader schwit1 shared the notice (PDF) published Tuesday by the FAA. Forbes reports: Technological advances "will eliminate the old sonic boom," FAA Administrator Bryan Bedford said in a statement. "This means we can ultimately repeal the ban from the 1970s on supersonic flight over U.S. territory while minimizing noise impacts to residents in communities along the route and near airports." The primary reason was public opposition to loud sonic booms. In the 1960s, a plane flying faster than the speed of sound -- about 660 mph at high altitudes -- created shock waves that traveled to the ground and reached human ears as a loud gunshot-like crack or thunder-like boom. Tests during that decade, including the Oklahoma City sonic boom experiments, found repeated booms broke windows, damaged property and generated thousands of public complaints. In its 1973 ruling, the FAA stated that due to the limits of technology at that time, "a prohibition was needed to protect the public from sonic boom .... by preventing operations of a civil aircraft at a true flight Mach number greater than 1." Several years later, Air France and British Airways introduced Concorde, and were allowed to serve New York's John F. Kennedy International Airport as long as flights remained subsonic over U.S. land. Notably, "the prestigious London-New York service was the only truly profitable [Concorde] route, supported by high-powered business and celebrity travel," wrote a former British Airways network planner for Forbes in 2021. Several U.S. companies are working on a new generation of luxurious supersonic passenger aircraft with much quieter sonic booms and improved fuel efficiency. In particular, Colorado-headquartered Boom Supersonic says it has pre-orders from United Airlines, American Airlines and Japan Airlines for its Overture jets, which will carry 60-80 passengers. Atlanta-based Spike Aerospace is developing smaller Diplomat jets for up to 18 passengers. Both companies' websites tout future transatlantic flights in under four hours.

"South Korea plans to train every single member of its nearly half-million-strong military to operate drones as easily as they handle personal firearms," reports Ars Technica: The goal is to make drones a "universal combat tool" for all troops by training them to use drones like a "second personal weapon," said Ahn Gyu-back, South Korea's Minister of National Defense, in a June 26 briefing reported by Reuters and other media outlets. The announcement coincides with broader plans to equip individual military units with more cheap and expendable drones for surveillance and strike missions, along with deploying more counter-drone lasers and microwave weapons. Meanwhile, South Korea's former drone operations command headquarters that used to have direct command authority over combat units will be reorganized to focus on collaborating with South Korean industry on developing and procuring commercial drone technology, according to The Korea Times. The South Korean defense minister specifically cited the conflicts in Ukraine and the Middle East as inspiring such military reforms with a focus on drone technologies... Ukraine's use of drones and military robots as a force multiplier to offset its numerical disadvantage on the battlefield versus Russia's larger military may carry special resonance for South Korea, given that the South Korean military's current active-duty strength of 450,000 personnel faces a numerical disadvantage against North Korea's active-duty military consisting of more than 1.2 million soldiers... The defense ministry is starting out by providing 11,000 "training drones" to military personnel this year, with the goal of eventually deploying 60,000 drones across the military by 2029. An additional complication comes from the South Korean military looking to procure drones with 100 percent domestically produced components and no Chinese components due to security concerns, according to the defense minister's comments reported by Reuters... South Korean companies are building new military attack drones, but the defense ministry may struggle to find enough commercial drones made without Chinese components to train hundreds of thousands of military conscripts, said Min-Cheol Jung, a cofounder of the Team Retriever counter-drone red team based in South Korea, in a War on the Rocks article.

schwit1 shares a report from The Wall Street Journal: The European Union Aviation Safety Agency has ordered (PDF) urgent inspections of 16 Airbus A380 planes operated by Emirates and Qantas, after cracks were found in a wing component on some aircraft (source paywalled; alternative source).. Cracks were found during earlier inspections of the wing spars structure, a key component of the wing, EASA said in a directive effective Wednesday. EASA determined that they "could reduce the structural integrity of the wing." "To address this potential unsafe condition, Airbus determined that an additional special detailed inspection has to be accomplished," EASA said. The first group of five aircraft, operated by Emirates, need to be inspected immediately, while the second group of 11 aircraft can be inspected later but within 25 flight cycles, EASA said in a separate statement. From the second group, 10 are operated by Emirates and one by Qantas, the aviation safety agency said.

Longtime Slashdot reader schwit1 shares a report from autoevolution: The U.S. Department of Commerce's Bureau of Industry and Security denied Polestar an authorization under the Connected Vehicle Rule. Polestar will continue to sell its existing inventory of Polestar 3 and 4 crossovers in the United States and will continue to offer support to customers and access to its service network. But no new 2027 models will set wheels on American soil. The Connected Vehicle Rule is a regulation that restricts the import and sale of vehicles equipped with Vehicle Connectivity Systems (VCS) and Automated Driving Systems (ADS) tied to foreign adversaries, primarily from China and Russia. Polestar is owned by Chinese auto giant Geely, which has also been the parent company of Swedish brand Volvo since 2010. However, Volvo has recently been granted authorization to sell connected vehicles in the United States. The rule, set out by the Bureau of Industry and Security (BIS), classifies modern vehicles as mobile data centers and is designed to protect national security by keeping sensitive driver data and vehicle control systems out of the hands of foreign governments. Michael Lohscheller, Polestar CEO, confirms that the company is well aware that the automotive industry is entering a new phase, based on regional dynamics. So, Polestar will shift its strategy to its biggest market as it is preparing its exit from the U.S. market. The report notes that Polestar sold 5,384 cars in the U.S. in 2025, with 60,119 units sold globally.

joshuark shares a report from Car and Driver: A new study conducted by the New York Times shows that the increase in vehicle hood height seen over the last two and a half decades, mainly due to the rise in popularity of large SUVs and trucks, has resulted in several thousand deaths that otherwise may not have happened. The study shows that while automakers and regulators have focused on occupant safety, they have turned a blind eye to pedestrian safety, which has fallen since around 2009. Researchers looked at four main datasets in their investigation: crash test data from the National Highway Traffic Safety Administration's (NHTSA) Crash Report Sampling System (CRSS) from 2016 to 2024; NHTSA's Fatality Analysis Reporting System (FARS); vehicle measurement data from Expert AutoStats; and vehicle registration data from S&P Global from 2002 to 2024. The researchers concluded that the increased danger to pedestrians is caused by two main culprits. First, large SUVs and trucks have taller hoods, raising the point of impact above most people's center of gravity and pushing them to the ground, typically hard asphalt, rather than up and onto the hood, which is designed to absorb impacts. Second, with larger A-pillars designed to protect occupants in rollover crashes, modern cars tend to have larger blind spots than cars sold at the turn of the century (presuming the 21st century). The shift toward vehicles with taller hoods led to roughly 3000 deaths between 2016 and 2024. This number is conservative because it does not include crashes that take place in parking lots, driveways, or private roads, which aren't part of the federal database. The data also showed an estimated 2.8 percent increase in the odds of a pedestrian fatality for every one-inch increase in vehicle hood height. Between two different scenarios, one decreasing the hood height of every vehicle in the dataset by 3 inches, and the second using a random sampling of hood heights from 2002 across 10,000 simulated crashes, between 2624 (for scenario two) and 3077 (for scenario one) lives could have been saved from 2016 to 2024.

Slate Auto says its stripped-down electric pickup will start at $24,950 before fees, with the base model's estimated range increased from 150 to about 205 miles. The company has started taking preorders on Wednesday. "The aggressive pricing -- half the average cost of a new car in the United States -- puts Slate in position to capture a share of the lowest end of the new car market, which has few gas and fewer electric options these days," reports TechCrunch. From the report: The price reveal comes more than a year after Slate Auto emerged from stealth. Since then, the company has been steadily detailing the extremely basic, transforming EV, which starts as a two-seater pickup truck, but can be modified into a five-seater SUV. The SUV version will start at $29,950, Slate said Wednesday. Slate has said the conversion can be done by professionals or by owners themselves. On Wednesday, it finally showed off some of the first of its "Slate University" how-to videos, which guide people through the steps for doing everything from the SUV conversion to adding headlight covers. Everything else about the truck is bare, though it's customizable. It has hand-crank windows, lacks an infotainment system, and all orders start with the same gray composite material, with no paint options, as Slate plans to let buyers order customizable wraps for the vehicle. That likely helps cut out a major cost center, as factory paint shops can run in the hundreds of millions of dollars. The company did not offer more details about the buying process. Slate has said it "won't have traditional dealerships," and plans to sell directly to customers, similar to other EV companies like Tesla, Rivian, and Lucid Motors.

An anonymous reader quotes a report from Ars Technica: The driving technology company Mobileye plans to launch a robotaxi service in an as-yet-unnamed US city in 2027, it said earlier today. The service will be vertically integrated, using Mobileye's Moovit mobility platform to interact with customers booking rides, coordinate drivers, and so on. The Israeli company, which was bought by Intel in 2017 before going public again in 2022, says it will start with around 100 robotaxis early next year. The company first rose to prominence in the mid-2010s, when Tesla began using Mobileye's advanced driving assistance systems (ADAS) as part of Autopilot. That relationship lasted until 2016, when Mobileye dropped Tesla as a customer after being alarmed that a driver assistance system was being sold to end users as driverless technology. Since then, Mobileye has continued to work with other partners on ADAS and autonomous vehicles. It has developed a new "SuperVision" ADAS that combines cameras and radar sensors, used by Porsche and Polestar, among others. On the robotaxi front, it has partnered with Volkswagen Group's MOIA to develop a commercially available robotaxi based on the VW ID. Buzz minivan, and last year, Mobileye revealed plans to work with Lyft to deploy robotaxis in Dallas, "as soon as" this year. [...] If Mobileye's experience with the initial 100 robotaxis goes well, it says it will scale up to around 17,000 robotaxis within the following five years. "The robotaxi revolution has only just begun, and its potential for transforming how we travel around the world continues to increase," Shashua said. "This initiative is not a replacement for our existing partnerships; it is an extension of them," said Amnon Shashua, founder and CEO of Mobileye. "We remain deeply committed to enabling automakers and mobility providers with Mobileye Drive. At the same time, operating our own service allows us to accelerate adoption, gain direct operational experience, and showcase the full potential of autonomous mobility."

Riverside County has launched an 8-mile "smart freeway" pilot on northbound I-15 near Temecula, using roadway sensors and an algorithm to coordinate ramp meters and suggest speeds rather than widening the freeway. Officials say the $33 million project could reduce stop-and-go traffic and travel times. According to SFGATE, similar systems in Australia and Denver reportedly cutting delays by 20% to 65%. From the report: Unlike typical on-ramp stoplights that run on a timer lasting a few seconds, Interstate 15 drivers could find themselves waiting up to four minutes or even longer while the system determines the necessary speed for traffic entering the freeway. By spacing out the cars, transportation officials hope to improve traffic flow, reduce stop-and-go traffic and decrease the amount of time that travelers have to spend on the freeway. The transportation commission spent $33 million to build the project, which will run for two years. Riverside County Transportation Commission spokesperson David Knudsen told SFGATE that if the program is successful, the agency will work with Caltrans to deploy it elsewhere in the county and then potentially to other traffic choke points in California. "This system is a lot less expensive than trying to build new lanes, and so the idea here is let's make the system that we have work better," he said. Knudsen said the program is not managed by artificial intelligence but instead uses advanced sensors in the roadway to monitor real-time traffic conditions and make adjustments. The stretch of freeway that connects Temecula at the Riverside/San Diego County line to the Interstate 215 interchange in Murrieta can be notoriously clogged. What can be less than a 10-minute drive with no traffic can take between 25 and 45 minutes during the afternoon peak period, according to the transportation commission. "The intent is to create a consistent flow of traffic on the freeway system, and the coordinated ramp metering among the three on-ramps ... will help do that," Knudsen said. "If we can manage that, then we can help prevent that stop-and-go traffic frustration that so many people feel ... on the freeway."

Sales have increased for Hyundai's under-$35,000 IONIQ 5, totalling 18,395 for the first five months of 2026, reports Electrek, "up 16% from the same period last year." But meanwhile BYD's overseas sales surpassed 160,000 for the first time last month, "up 80% from May 2025 and 19% from the previous record of 135,098 set in April." Through the first five months of 2026, BYD sold 616,263 vehicles overseas. In May, overseas sales accounted for over 41% of BYD's total sales. In several major markets, including the UK, BYD surpassed Tesla and Kia to become the best-selling EV brand through April. "With fuel prices remaining high, more drivers are turning to electric vehicles as a smarter and more economical choice," Bono Ge, BYD UK's Country Manager, said last month. Elsewhere Electrek notes that Toyota's bZ (starting at under $35,000) was the third-best-selling EV in the U.S. in the first three months of 2026, behind only the Tesla Model 3 and Model Y. "Last month, bZ sales doubled from May 2025, with 2,646 units sold." And meanwhile the first Volkswagen ID.

An anonymous reader quotes a report from Wired: Aerodynamic drag is a major "barrier" in high-speed airplanes, automobiles, and bullet trains. This is because a design with less aerodynamic drag allows the aircraft to move at higher speeds with less energy. When an aircraft or car body moves at high speed, a thin layer of air called the "boundary layer" is formed on its surface. This boundary layer has two states: laminar flow, in which air flows in an orderly fashion, and turbulent flow, which involves turbulence. The longer the air stays in the laminar flow state with low friction, the smaller the air resistance becomes, but as the air speed increases, it transitions to turbulent flow. The key to reducing aerodynamic drag is how to delay this transition to turbulence. For more than 80 years, the principle of "the surface of an object must be smooth" has been the basic premise of aeronautical engineering throughout the world in order to suppress the transition to turbulence and reduce aerodynamic drag. This premise was based on the results of a 1940 study by Ichiro Tani, a Japanese aerodynamicist who quantitatively demonstrated the relationship between "surface roughness" (an indicator of the state of the machined surface) and turbulent transition, arguing that surface roughness, which was unavoidable with the manufacturing technology of the time, prevented laminar flow from being realized. However, in 1989 Tani reinterpreted the experimental data on rough-surface pipes obtained by fluid engineer Johann Nikulase in the 1930s, bringing a new perspective that "roughness may not necessarily only promote turbulent transition and increase fluid resistance." Inheriting this idea, a research group led by Yasuaki Kohama of Tohoku University experimentally demonstrated in the 1990s that fibrous rough surfaces, which have fine fibrous irregularities on their surface, have the effect of delaying transition under certain conditions. The same Tohoku University research team recently announced a discovery that significantly advances this trend. Aiko Yakino, associate professor at Tohoku University's Institute of Fluid Science, and her research group were the first in the world to demonstrate that aerodynamic drag can be reduced by up to 43.6 percent simply by applying distributed micro-roughness (DMR), a surface roughness so fine and irregular that it cannot be distinguished by the naked eye. This technology is fundamentally different from the "rivulet (shark skin) process," which is known as a typical aerodynamic drag reduction technology. The rivulet process mimics the fine longitudinal grooves in shark skin, and by carving grooves approximately 0.1 mm wide along the direction of airflow, it aligns the vortices that occur near the wall surface of turbulent airflow areas. DMR, on the other hand, delays the switch from laminar to turbulent flow by means of random and minute irregularities. The flow zones it affects and the mechanisms it employs are based on completely different concepts.

An anonymous reader quotes a report from Reuters: Ride-share drivers for app-based companies such as Uber and Lyft have unionized in Massachusetts, forming what state officials and labor leaders said was the first officially recognized organization in the U.S. to represent such gig workers. The newly formed App Drivers Union received certification from the Massachusetts Department of Labor Relations on Friday to represent nearly 70,000 ride-share drivers operating as independent contractors in the state. "It changes the game for ride-share workers across this country," Massachusetts Governor Maura Healey, a Democrat, said at a rally with drivers and labor activists in Boston on Tuesday. The certification occurred after voters in November 2024 approved a ballot measure that created a novel framework to allow drivers for companies like Uber and Lyft to organize and bargain collectively over pay and benefits. That vote followed a years-long, nationwide battle over whether ride-share drivers should be considered independent contractors or employees entitled to benefits and wage protections.

Tesla's upcoming Cybercab "has been certified at 165 Wh/mi," reports Electrek — which makes it "the most efficient electric vehicle ever produced — by a wide margin." The next most efficient EV on the market, the Lucid Air Pure, consumes 28% more energy per mile. Tesla VP of Vehicle Engineering Lars Moravy confirmed the figure, which represents a certified rating — not a marketing claim or internal target. It's an impressive achievement, but it comes with a massive asterisk: Tesla accomplished this by building a tiny two-seat robotaxi with no steering wheel, no pedals, and a sub-50 kWh battery pack... Even Tesla's own Model 3 — one of the most efficient passenger EVs you can buy — needs nearly a third more energy to cover the same distance... Where the 165 Wh/mi figure genuinely matters is in the economics of running a robotaxi fleet. Energy cost per mile is one of the biggest operating expenses for any ride-hailing service, and the Cybercab's efficiency gives Tesla a structural cost advantage over competitors... The small battery pack also means faster charging times and lower per-vehicle battery costs — both critical for fleet economics. Tesla has said the Cybercab will cost $30,000, and the efficient powertrain is a big part of hitting that price target. Tesla confirmed Cybercab production has started at Giga Texas in April, though the ramp is expected to be slow initially. The company still hasn't solved unsupervised autonomous driving — the first steering wheel-less unit rolled off the line in February, but Tesla's supervised robotaxi fleet currently crashes at roughly four times the rate of human drivers.

Long-time Slashdot reader UnknowingFool shares this report from the BBC: Air France and Airbus have been found guilty of manslaughter over a 2009 plane crash which killed 228 people. The Paris Appeals Court found the airline and aircraft manufacturer "solely and entirely responsible" for the incident, in which flight AF447 from Rio de Janeiro to Paris crashed into the Atlantic Ocean. The passenger jet stalled during a storm and plunged into the water, killing all on board. A court had previously cleared the companies in April 2023, but they were found guilty on Thursday after an eight-week trial. Both have repeatedly denied the charges and say they will appeal... The companies have been asked to pay the maximum fine — €225,000 ($261,720; £194,500) each — but some victims' families have criticised the amount as a token penalty... In 2012, French investigators found a combination of technical failure involving ice in the plane's sensors and the pilots' inability to react to the aircraft stalling led to it plunging into the sea. The captain was on a break when the co-pilots became confused by faulty air-speed readings. They then mistakenly pointed the nose of the plane upwards when it stalled, instead of down. Investigators concluded the co-pilots did not have the training to deal with the situation. Pilot training has since been improved and the speed sensors replaced.
