Boeing's bestselling passenger jet is facing increased scrutiny after being involved in two deadly crashes in less than five months, a situation that threatens to tarnish the US plane maker's reputation for safety.Chinese aviation authorities on Monday told airlines in the country to ground all their Boeing 737 MAX 8 aircraft, citing the need for "strict control of safety risks." Some individual airlines are taking similar action elsewhere. And Boeing has postponed the debut of its new 777X jetliner, which was scheduled for this week, as it deals with the fallout from Sunday's disaster in Ethiopia.The flurry of negative headlines unsettled investors. Boeing shares dropped nearly 9% in premarket trading early Monday in New York.All 157 people on board a 737 MAX 8 operated by Ethiopian Airlines were killed when the plane crashed shortly after takeoff on Sunday morning. In late October, a 737 MAX 8 flown by Lion Air went down off the coast of Indonesia, killing 189 people.Both the Ethiopian Airlines and Lion Air planes were brand-new aircraft. And both crashed minutes into flight.Ethiopian Airlines said Monday that it was grounding its fleet of 737 MAX planes as an "extra safety precaution," and Cayman Airways, the main carrier of the Cayman Islands, said it would do the same until "more information is received."The circumstances of the two crashes remain under investigation, and Boeing has presented no evidence to suggest the two disasters are linked. The similarities may be a coincidence."A formal investigation will need to be conducted into this new crash. It's important not to speculate as to its causes. A final, conclusive report has yet to be issued in the case of the Lion [Air] crash," said Greg Waldron, Asia managing editor at aviation research firm FlightGlobal."That said, having two crashes of a brand new type in a short time is an unprecedented state of events," he added. "It is inevitable that this will affect perceptions about the 737 MAX family."The decision by Chinese authorities to ground 737 MAX 8 planes in the country is a serious blow."A suspension in China is very significant, as this is a major market for Boeing," Waldron said. Chinese airlines have 97 of the 737 MAX aircraft in service, more than a quarter of the total in operation worldwide, according to FlightGlobal.Boeing's bestsellerThe single-aisle Boeing 737 has been a workhorse on short- and medium-haul flights for decades. The 737 MAX is the latest version — and the company's bestselling aircraft by far. Airlines have ordered thousands of them.The two-year-old 737 MAX 8 model in particular is hugely popular (the MAX 9 only recently went on sale and Boeing has not yet delivered the MAX 10). Last year, 72% of Boeing's deliveries were 737 planes. Boeing plans to make 59 new 737s each month this year — more than four times the number of 787s, Boeing's next-best seller.Southwest Airlines has the largest fleet of 737 MAX 8 airplanes, followed by RyanAir and FlyDubai, according to 3018

LOUISVILLE, Ky. – The robotics lab at the University of Louisville is a lot like a toy shop. “You don’t feel like you’re working with them, more like you’re playing around with robots,” said Sumit Das, a researcher at the lab. For him, it’s a dream come true. “I was always tinkering with things and making new stuff and my parents always encouraging me to do new stuff and even if I failed, they would be like, ‘it’s ok, move on to the next project.’ So, it has always been a project after project after project,” said Das. But here’s the thing. He’s not playing around. Sumit and PhD student Shamsudeen Abubakar, who goes by Abu, are part of a research team building a robot to help people heal. “So, in my estimate, about 5 to 10 years, hopefully we’ll see them be able to work alongside nurses,” said Das. This is ARNA—the Adaptive Nursing Robot Assistant. ARNA is built to help nurses do their job. “So you push on this like a walker that elderly people use,” said Abubakar The robot can do a few things: monitor a patients vital signs, pick things up and bring them to a patient, and help them walk down a hallway. “This robot really has the potential to diminish the incident of patient falls,” said Cindi Logsdon, a nursing profesor at the University of Louisville. Patient falls are a big deal, and Logsdon knows. She’s a consultant on the project and was the Associate Chief of Nursing at the University of Louisville Hospital for almost 10 years. “A big reason that patients fall when they’re in hospitals is they try and get out of bed by themselves, or they try and reach something that they can’t reach, or they depend on the darn bedside table,” said Logsdon. According to the Agency for Health Care Research and Quality, between 700,000 and 1 million patients fall in hospitals each year. Everyone involved in the project is hoping the robot will make a big difference in the U.S. and abroad. “I’m from Nigeria which is a developing country and I think robotics offers an avenue to kind of, you know, not jump the steps in development but kind of close the gap,” said Abubakar. “If there are any of the basic sort of skills that a robot could take over in collaboration with the nurses, in partnership with a nurse, it frees up the nurse for more higher level activities,” said Logsdon. “It’s about how to assist them in doing tasks that can eat their time up,” said Das. I know what you’re thinking. Sure these robots may help us heal in the hospital, but what’s to stop them from becoming self-aware and destroying the human race? “I think that’s limited to fiction. I don’t think that’s going to be a reality as it’s shown in Hollywood. I wouldn’t be worried about that,” said Das. 2725

ARAPAHOE COUNTY, Colorado — An argument over not getting recognition for testing done at Aurora West College Preparatory Academy led one of the school’s deans of instruction to bring a gun to campus and threaten school officials earlier this week, an affidavit released Friday reveals. Tushar Rae, 30, was arrested Wednesday and remains in Denver jail on suspicion of carrying a weapon on school grounds, a class 6 felony; as well as carrying a concealed weapon, a class 2 misdemeanor. His bond was set at 0,000. The affidavit states Principal Taisiya “Taya” Tselolikhina had an argument with Rae on Tuesday over testing that the school was administering to students “and about not receiving acknowledgement and recognition he felt was owed.” The following day, Tselolikhina received a text at around 2 p.m. from Rae, telling her to meet in his office after the dean of instruction didn’t show up to school the whole day, and didn't inform anyone he was going to be absent.Once in the office, Rae reportedly pulled a black handgun from his waistband and placed the gun on the counter. Rae then said, “Try and f—k with me. You shouldn’t have said what you said. I don’t want to hurt you. I’m going to hurt all the people around you,” according to the affidavit. He then said he was going to “shoot the kneecaps off of Jessica and Denise.” Jessica Rodriguez is an assistant principal at the school and Denise Huber is another dean of instruction. The probable cause statement notes he then asked the principal what she was going to do about it. "I came prepared,” Rae allegedly told Tselolikhina before he patted his pocket adding that “he had two extra rounds.” Rae then told the principal to walk away or he would “shoot the next person outside the door,” police documents state. As he made the statement, there was a knock on the door. Rae then reportedly picked up the gun and placed it back into his waistband and answered the door. On the other side were two students and the report states Rae had a brief talk with them. It does not state, however, what the dean of instruction told the students. Tselolikhina then left Rae’s office and began to place the school on lockdown, according to the affidavit. The incident “prompted a large scale police call for service and numerous officers responded to the school,” the probable cause statement states. Investigators said one of the responding officers talked with the principal while another was on the phone with the suspect, who did not initially tell the officer where he was. Rae then told the officer that some of the school staff had been harassing him, but the suspect did not provide further details to the officer during their conversation. According to the affidavit, Rae also admitted to sending text messages earlier “that he should not have sent,” but it’s unclear what the content of those message was, as the suspect did not provide further details to police. The probable cause statement states Rae “expressed concern” about the school being on lockdown and told the officer on the phone he wanted the lockdown lifted so the soccer team could play a game scheduled for later that day. The suspect then told the officer he was at his house and police went to his address, where they found a Remington handgun and three magazines in Rae’s bedroom cabinet. He was arrested and held on a bond on suspicion of felony menacing and misdemeanor interference with staff, faculty, or students of educational institutions, but posted pond and was released before he was able to be issued a restraining order. His bonding out caused Aurora Police to send officers to Aurora West College Preparatory Academy as well as the homes of school staff to make sure they were safe. Rae was then booked into Denver’s Downtown Detention Center on Thursday on a fugitive of justice hold from the Arapahoe County Sheriff’s Office. Initial communications to parents didn’t tell the whole story Communications to parents following the lockdown on Wednesday told a different story about what took place inside the school as hundreds of kids were still in class. A call from the principal made to parents on Wednesday stated that both Aurora Public School officials and the Aurora Police Department investigated a possible threat at the school and that “there were rumors of an armed individual in the area” – hours after the district, school administrators and the school principal were aware Rae was on campus allegedly armed with a gun and reportedly making threats.A second call from the school on Thursday state that after school officials learned about the allegations, “we promptly placed the employee on administrative leave."According to the statement from the school, Rae is not allowed on school grounds pending the outcome of the criminal investigation.Students walk out after learning what happened Dozens of students walked out of class at the school Friday morning, saying they were not told that Rae allegedly brought a gun to the school Wednesday and made the threats. 5054

PARADISE, Calif. – Parts of California are going dark and some people are taking it personally. “It’s like a slap in the face,” said Paradise, California, resident Jonathan Valdez. “It’s like we have to keep suffering over and over again.” Valdez stocked up on gas for his generators after Pacific Gas and Electric warned it could shut off power to almost 200,000 people across the state in an attempt to lower the risks of wildfires. “Gas went up so I’m kind of sweating it a little bit,” Valdez said. “It’s another extra dollar for each can and we have to do this every day.” Several businesses say the power shutdowns have hurt their sales. “People can’t work, people can’t pay their bills,” said a worker at the local gas station. “And people up here in California, we live paycheck to paycheck.” The employee says the gas station lost products without electricity. She added many feel in the Northern California community that they’re being targeted by the power company. “A lot of people think they’re doing it to get back at the people of Paradise,” she said. Getting back because several people are now suing PG&E after investigations found their equipment started the Camp Fire – the most expensive and deadly wildfire in California history. Paul Moreno of PG&E says these planned power outages aren’t happening out of revenge – they are happening to keep cities and citizens safe. “No. No. There’s nothing like that. This is being done for public safety,” Moreno said. “Last time we did a public safety power shutoff, we found 100 cases of damage caused by high winds to our powerlines any number of those could have started a fire. With the high winds it could have been catastrophic.” These potentially catastrophic conditions have first responders on high alert. “It’s really flammable and fire is really dynamic,” said Rick Carhart of Cal Fire Butte County. Carhart says Cal Fire has increased staffing after issuing a Red Flag Warning – adding people need to take safety into their own hands. "You need to have 10 feet of an area around the generator down to bare dirt," he said. Having a plan in place, just like the local schools. After closing classes for three days during another power shutoff, Paradise Junior and High Schools aren’t taking any chances this time. Staff will use lanterns to light classes and plan on running generators to access the internet. “That may sound strange, but we ran a school out of a hardware store last year,” said Larry Johnson, Principal at Paradise Junior & Senior High School. “So, a couple of lanterns, you know, we got this.” Town officials, however, aren’t as optimistic. “There’s not a lot we can do about it,” said Paradise Mayor Jody Jones. “We don’t even have generators that the town has.” Jones isn’t pleased with PG&E. And after seeing much of her city go up in flames, she’s now calling them out – saying PG&E should have spent more money on maintenance. “I think there’s a lot of evidence that they haven’t been doing the maintenance that they need to do doing,” she said. “I wish that they would have invested in their system.” When the power did go out in Paradise, some had their own systems in place. Nicki Jones of Nic’s Food, Beer and Wine bought a generator to keep her business up and running. Saying it’s an investment for both her and her customers. “We’re able to serve the community,” she said. “We open up at 7 a.m. We serve coffee and we have a gathering place for the community.” Those looking to travel out of this community, however, may have a hard time. “Everything else is closed,” a local man said. “So, I’m going to have to get gas in Chico.” Back at the local gas station, people found the doors chained up and pumps shutdown. “It’s a big inconvenience going down to Chico,” the man said. “Everything in Magalia is closed and everything in Paradise is closed.” But despite the hardships, people are staying positive during these planned power shutoffs and seeing light in this time of darkness.“We’re Paradise strong,” Jody Jones said. “We’re pioneers. We can do it.” 4113
