(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

Country singer Chase Rice is facing criticism for playing a concert in Tennessee as COVID-19 cases continue to surge. Rice posted video on Instagram of his packed show at Brushy Mountain State Penitentiary, which is a music venue about three hours east of Nashville in Petros.People on social media pointed out the lack of masks and social distancing.Kelsea Ballerini was among those calling Rice out, tweeting in part: "Imagine being selfish enough to put thousands of people’s health at risk, not to mention the potential ripple effect, and play a NORMAL country concert right now." Imagine being selfish enough to put thousands of people’s health at risk, not to mention the potential ripple effect, and play a NORMAL country concert right now. @ChaseRiceMusic, We all want (and need) to tour. We just care about our fans and their families enough to wait. ?????♀? https://t.co/eJaLnGu28k— Kelsea Ballerini (@KelseaBallerini) June 28, 2020 The venue says it followed state guidelines, including reducing capacity from 10,000 to 4,000 and requiring temperature checks at the door.

With the Food and Drug Administration (FDA) yet to develop a regulatory framework for CBD-infused products, states are stepping in. This week, Illinois introduced new legislation that could require the testing of CBD products sold in its state. The hemp-derived cannabidiol, or CBD, is sold as a supplement, promising to manage everything from anxiety and insomnia to chronic pain.Rahul Easwar, co-founder of Chicago-based CBD-retailer LeafyQuick, says the product is everywhere.“Gummies, edibles, we’ve got bath bombs, salts, topical lotions," Easwar says. "You name it, there’s CBD in it.”But while some CBD shops like LeafyQuick only sell products that have been tested, there are no laws requiring that. “We don’t obviously accept every brand that knocks on our door, and we go through a very stringent due-diligence process,” says Easwar.And because CBD products are considered supplements rather than drugs, they remain largely unregulated. Since 2015 the Food and Drug Administration has issued more than four dozen warning letters to firms marketing unapproved drugs allegedly containing CBD. Many did not contain the levels of the cannabis derivative they claimed to.It’s that uncertainty about what’s in the products that prompted Illinois state representative Bob Morgan to act. “These are products coming in from other states more often than not are not being tested,” says Morgan. “We don't know if they have heavy metals pesticides contaminants synthetic THC or something way worse.”Morgan is pushing a bill that would require all CBD products sold in the state to pass minimum testing standards. “We should have these high expectations, especially since people were consuming this product,” says Morgan. “These are things people are ingesting and we have to make sure they’re safe.”If they’re not safe, the proposed law would require untested products to be pulled from shelves and online. Sellers violating the law could face stiff fines.It’s something retailers like Rahul Easwar say is essential to the CBD business' long-term success.“Especially retailers, more so the consumers need to demand such regulations and more stringent regulations in my opinion.”For now, there are still no national standards for CBD testing. Morgan says until federal regulators catch it’s up to the states to take the lead. 2334

(AP) — TikTok's owner has chosen Oracle over Microsoft as its preferred suitor to buy the popular video-sharing app, according to a source familiar with the deal. The choice came a week before President Donald Trump’s deadline to ban it in the U.S. Microsoft said in a Sunday statement that TikTok’s parent company, Bytedance, “let us know today they would not be selling TikTok’s US operations to Microsoft.” The Trump administration has threatened to ban TikTok by mid-September and ordered ByteDance to sell its U.S. business, claiming national-security risks due to its Chinese ownership. 600
