(AP) - There was a loud bang, and suddenly the Southwest Airlines jet rolled sharply to the left. Smoke began to fill the cabin, and flight attendants rushed row by row to make sure all passengers could get oxygen from their masks.When flight attendant Rachel Fernheimer got to row 14, she saw a woman strapped in her lap belt but with her head, torso and arm hanging out a broken window.Fernheimer grabbed one of the woman's legs while flight attendant Seanique Mallory grabbed her lower body. They described being unable to bring the woman back in the plane until two male passengers stepped in to help.The harrowing details from the April 17 fatal flight were released for the first time as the National Transportation Safety Board began a hearing Wednesday into the engine failure on Southwest Flight 1380, which carried 144 passengers and five crew members.The flight attendants told investigators at least one of the male passengers put his arm out of the window and wrapped it around the woman's shoulder to help pull her back in. Fernheimer said when she looked out the window, she could see that one of the plane's engines was shattered, and there was blood on the outside of the aircraft.Flight attendants asked for medical volunteers. A paramedic laid the woman across a row of seats and began chest compressions. They tried a defibrillator but it indicated that there was no shock. The paramedic and a nurse took turns at CPR.Passengers asked if they were going to die. Fernheimer said she squeezed their hands. "She told them that they were going to make it," an investigator wrote.Pilots Tammie Jo Shults and Darren Ellisor landed the crippled Boeing 737 in Philadelphia. The passenger in the window seat, Jennifer Riordan, was fatally injured — the first death on a U.S. airline flight since 2009. Eight other passengers including at least one of the men who helped pull Riordan back in the window.Wednesday's hearing in Washington focused on design and inspection of fan blades on the engine, made by CFM International, a joint venture of General Electric and France's Safran S.A.An official from CFM defended the design and testing of fan blades like the one that snapped on the Southwest plane as it flew high above Pennsylvania, triggering an engine breakup that flung debris like shrapnel into the plane.After the fatal accident, CFM recommended the use of frequent and more sophisticated tests using ultrasound or electrical currents.Another Southwest jet had suffered a similar blade-related engine breakup in 2016 over Florida.CFM and federal regulators considered the Florida incident an aberration."We determined early that we would require some corrective action in that it was an unsafe condition," an FAA expert on engines, Christopher Spinney, testified on Wednesday, "but we also determined we had some time."Rather than order immediate inspections of fan blades after the 2016 incident, the FAA began a slower process for drafting a regulation and getting public comment before enacting it. That process was still underway when the fatal accident occurred nearly two years later.Since the deadly flight, widespread inspections have turned up eight other fan blades on similar CFM engines that also had cracks. The fan blade that broke was last inspected six years earlier and, it was determined, suffered from metal fatigue even then — but it went unnoticed by a less sophisticated exam used at the time.Fan blades have been thought to have no real lifetime limit. CFM and FAA officials said they were now considering whether blades must be replaced at some point even if they don't show wear.Representatives from CFM also testified about testing and certification of jet engines, which are supposed to be built to prevent pieces from breaking off and flying free.The investigation is continuing. Most of Wednesday's hearing was highly technical. It was led by one of the safety board's five members, Bella Dinh-Zarr. The full board is expected to determine a probable cause for the accident in the next several months.Meanwhile, Riordan's husband, Michael, said in a statement on behalf of his family that they were "grateful for the heroic actions of the passengers who tried to save Jennifer's life.""The most important thing now is making sure that the aircraft and engine failures that caused Jennifer's untimely and unnecessary death never happen again," he said. 4408

(CNN) -- Eco-friendly meatless food products shook up the fast food industry in 2019. Experts say next year's game-changing trend in sustainable consumer goods may be plant-based -- or "vegan" -- athletic shoes.Last week, Reebok, owned by Adidas since 2005, unveiled the design for its first plant-based running shoe, the Floatride GROW, which is expected to hit store shelves in the fall of 2020.The upper part of the shoe is made primarily from eucalyptus. Its soles are made from castor beans and natural rubber. The scheduled debut comes two years after Reebok started selling a "vegan" version of its famed Newport (NP) Classic shoes made with cotton and corn. The more sustainable version of the NP Classics are "lifestyle" footwear not designed for athletic performance.In contrast, Reebok brand president Matt O'Toole says the Floatride GROW is sturdy enough to handle the wear and tear from intense and constant use by athletes."One of the challenges for the innovations team was [the Floatride GROW] had to be equal to or better to" the vegan NP Classics, O'Toole told CNN Business. "We actually have our own testing machines. The shoe holds up just as well as our other [athletic] shoes."Reebok and Adidas are just two of the major athletic retailers vying to get in on the ground floor of what experts expect to eventually be a booming plant-based sneaker market, as discarded footwear fills up US landfills.Americans throw away some 300 million pairs of shoes each year, according to the US Department of the Interior. Combined with discarded clothes, the EPA says those shoes accounted for roughly 8.9 million tons -- about 17.6% -- of the 50.7 million tons of trash that filled American landfills in 2017.Most shoe waste is comprised of non-biodegradable plastic, leather and petroleum-based rubber, materials that take an average of 25 to 80 years to decompose naturally, multiple shoe companies told CNN Business.In recent years, calls for climate change reform and for major corporations to engage in more sustainable business practices have created a niche market among young people who are interested in shoes that are more biodegradable.In 2017, the global market for athletic footwear reached an estimated .3 billion, according to Grand View Research analysis, which concluded the market would increase by more than 5% by 2025.A 2019 "future of footwear" study commissioned by the market research firm NPD found that Millennials and Generation Z, the primary consumers of athletic footwear, are "very concerned" about the environment."Our survey shows that consumers were concerned about where their shoes were made and whether or not they were made ethically," NPD senior sports industry advisor Matt Powell told CNN Business. "About 35% of respondents said they would be willing to pay more for a shoe sustainability made. While it isn't the entire market, that's certainly a category for growth."Nike dipped its toe in the plant-based, athletic shoe waters a few months ago, with the limited release of a "100% organic" custom Nike Air Max 90. The industry leader in athletic footwear partnered with environmentally-conscious, UK streetwear brand Maharishi to create and raffle off pairs of its own "vegan" shoe in August for 0 apiece.The shoes have been resold for as much as ,446 per pair on second-hand retail sites.Maharashi sales associate Miles Chick said the promotion's organizers were inundated with requests to enter the online raffle for Nike's vegan sneakers. "When word spread, it just started kind of ringing alarms in the vegan community," he said.Nike says sustainability has been at the core of its business for decades, but noted that recent research about climate change has compelled the company to change the way it makes and sells its shoes.In 2015 and 2016, Greenpeace criticized Nike and a few other companies for failing to eliminate their use of perfluorinated chemicals (PFCs), which protect products from corrosion, but also make them more harmful to the environment.In August, Nike, Adidas and Puma joined 30 other apparel companies as signatories on the G7 Fashion Pact, which French Prime Minister Emmanuel Macron unveiled at the annual G7 Summit. Nike has also committed to reducing its carbon footprint by 30% by 2030 through its partnership with the UN Framework Convention on Climate Change."We exist to serve athletes. ... We know that if there is no planet there is no sport," a Nike spokesperson told CNN Business in an emailed statement. "Advancing a more sustainable future requires companies of all sizes to think holistically, innovate solutions and adopt the principles of circularity."Powell, the sports industry advisor, says the jury is still out on how many Americans will purchase shoes made from more sustainable materials over the versions they know and love."I think there's a whole lot of other things that go into what makes a shoe successful," he said. "The style has to be right and the shoe has to perform. Reebok knows how to make shoes. I'm pretty convinced this shoe will do well." 5081

(AP) — The U.S. communications regulator on Tuesday proposed a 5 million fine, its largest ever, against two health insurance telemarketers for spamming people with 1 billion robocalls using fake phone numbers. The Federal Communications Commission said John Spiller and Jakob Mears made the calls through two businesses that purported to sell products from major insurers but actually worked on behalf of other companies. State attorneys general of Arkansas, Indiana, Michigan, Missouri, North Carolina, Ohio, and Texas also sued the two men and their companies, Rising Eagle and JSquared Telecom, in federal court in Texas, where both men live, for violating the federal law governing telemarketing, the Telephone Consumer Protection Act.According to the FCC, the robocalls offered plans from insurers like Aetna and UnitedHealth with an automated message. But if consumers pressed a button for more information, they were forwarded to a call center that sold plans that weren't connected to the insurers.Consumers weren't the only ones annoyed by the calls. The companies advertised in the fake calls also received angry calls and were the target of lawsuits from consumers. 1188

EL CAJON, Calif. (KGTV) - Tyson Kirkpatrick's family is one of the first to own a home in Main Ranch - a planned development on the northeast end of El Cajon.They bought their brand new single-family home for a price in the low 500-thousands. That was about 0,000 less than the similar properties they were looking for over at Santee Lakes. "It was more of our price point," Kirkpatrick said. "It makes me feel great. It makes me feel very fortunate to be here."Main Ranch will ultimately grow to more than 130 new homes.Complete Coverage: Life in El CajonIn the last two years, El Cajon has seen as many as 850 new housing units get built. Prices for single family homes in the city are as much as 20 percent below the median for the county, which CoreLogic says was 0,000 in October. "We made a calculated decision that we wanted to be more competitive in this market," said El Cajon Mayor Bill Wells.Wells said the city has taken three key steps to attract builders. First, it eliminated developer impact fees which pay for important infrastructure related to the growth. The City of San Diego, for instance, charges as much as ,000 per unit. In El Cajon, the city instead relies on its general fund, boosted by a half-cent sales tax that expires in 2029, an issue now being studied at City Hall. Last April, the City Council hired a consulting firm to explore adding fees to developments, but Wells said he does not expect that to happen or any financial headwinds. "We're careful about how we spend our money, and we make sure we have to have enough money to take care of it," said Wells.The city also changed its zoning to allow developers who meet certain requirements to build without a public hearing. That reduces chances for opposition and costly delay.Finally, El Cajon has taken a more customer-service approach to interacting with developers whether for permitting at city hall or inspections on site. "In the City of El Cajon, it's tough but fair, and they give you a chance to alleviate some of their concerns on the spot," said Dan Scott, the construction superintendent at Main Ranch. In all, Wells says El Cajon is a great place to raise a family. He says adding housing that's affordable is a key way the city can encourage people to come see that for themselves. 2302
