The Federal Aviation Administration on Friday ordered new inspection requirements for engines similar to the one that failed earlier in the week on a Southwest Airlines flight, resulting in a passenger's death.The emergency airworthiness directive will require airlines to perform an ultrasonic inspection of certain CFM56-7B engines within 20 days of receipt of the order, it said. Federal safety investigators have said the naked eye cannot detect the cracks and signs of metal fatigue that doomed the engine on Southwest Flight 1380."We are issuing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design," the directive said.The Southwest Boeing 737 took off Tuesday morning from New York, headed for Dallas. About 20 minutes into the flight, at about 32,500 feet, a fan blade broke off the engine and shrapnel shattered a window.Jennifer Riordan, 43 and a mother of two, was sucked out of the broken window and pulled back inside by fellow passengers. She died from blunt force trauma at a hospital after the plane's emergency landing in Philadelphia.The new inspection is to be done while the engine is on the aircraft's wing. Inspections take between two and four hours per engine, according to the FAA and manufacturer.Friday's announcement came shortly after the engine manufacturer, CFM International, issued a service bulletin recommending the CFM56-7B engine be inspected more frequently. After reaching a certain age, the engines should be inspected approximately every two years, the manufacturer said.The manufacturer told CNN it has been working with the FAA on the inspection procedures.  1749

The excitement of two COVID-19 vaccines with more than 90 percent efficacy is undeniable.In November, both Pfizer and Moderna announced its scientists had developed vaccines with efficacy at or near 95 percent, but scientists are warning these vaccines are not the "silver bullet" to ending the pandemic.“We don’t want to give the public the impression that there’s an emergency use authorization and these vaccines become available in a small amount in December and we can go back to our pre-pandemic behavior,” said William Moss, executive director of the International Vaccine Access Center at Johns Hopkins.In June, the FDA released its vaccine guidelines, saying it would consider emergency use authorization for any vaccine testing with at least 50 percent effectiveness, so there is a reason for celebration, according to Moss, but only after certain questions about the vaccine are answered.Dr. Anthony Fauci has said the initial vaccines will prevent symptoms in those who become infected, rather than kill the virus itself. Moss says that means immunized people might be able to spread COVID-19 to others.He also wonders how long immunization will last. One year? Three years? Will booster doses be needed? They're all careful considerations that will only emerge once one is put into play, according to Moss.“It’s obviously tragic that the [COVID] cases are occurring that quickly, but it does help a vaccine trial because otherwise you just have to wait that much longer for samples to come in,” said Moss.The vaccine process has innovated how scientists and researchers approach these types of situations, however, according to Moss.In traditional vaccines, a small dose of the virus is injected into the body so the immune system can create antibodies. In the COVID-19 vaccine, though, both Moderna and Pfizer have used what is called messenger RNA (mRNA) where the virus’ genetic code is injected into the body so it can instruct cells on what antibodies to produce. Scientists say this way is faster, safer, and can create a stronger immune response as people are not exposed to the virus.“I suspect that if this all goes well and these vaccines are safe and continue to demonstrate 90 to 95 percent efficacy, we’re going to see other vaccines of a similar type,” said Moss. 2298

The girlfriend of the man killed Thursday after a shooting in a Nashville mall was taken into custody on gun charges. According to an affidavit from Metro Nashville Police, Alexandria Lavender was arrested on two counts of theft of property, ,000 or less, and unlawful gun possession for having two stolen guns with her. The shooting happened just before 2:30 p.m. local time Thursday inside a hallway near an Auntie Anne's pretzel shop, just across from an Old Navy store. Police said two men – identified as Justin Golson and Demarco Churchwell – got into an argument that led to gunfire.Churchwell was taken to Skyline Medical Center in critical condition, where he later died. Golson was arrested and charged with criminal homicide. According to police documents, Churchwell’s girlfriend – Alexandria Lavender – was with him as he was being extracted from the mall. A witness said she had a gun in her purse, which police said could be seen in plain view from the top of the bag. Authorities said she did not have a valid handgun permit. The guns were checked by police records and were found to be reported stolen out of Dickson and Davidson counties.   1238

The federal government says the fund providing a 0 weekly unemployment insurance boost is running out, but all eligible unemployed workers will still get their share. The Federal Emergency Management Agency says the jobless boost will end up providing benefits for just six weeks. The program was created last month by President Donald Trump to replace a more generous 0-a-week supplement that had been authorized by Congress but expired. So far, billion of the billion set aside for the program has been sent to states and U.S. territories. 563

The elections board in Florida's Miami-Dade County has collected a set of mysterious ballots in the Opa-locka mail facility after Democrats raised concern about the uncounted votes.The uncounted ballots have emerged as one of many battles over the fiercely contested Florida elections that moved this weekend into a recount phase.Suzy Trutie, a spokesperson for the county's supervisor of elections, told CNN there were 266 ballots in the shipment and that the votes will not be counted. Florida law requires all ballots sent by mail to arrive at the election facility by 7 p.m. on Election Day, and these ballots did not meet that standard, Trutie said.The US Postal Service said in a statement on Friday that it was operating in "close coordination and partnerships with election officials at the local, county and state levels." But as of Sunday morning, it still did not confirm ballots had not been provided in time to local election officials. 957
