ATLANTA - In a memo this week, Delta Airlines’ CEO told staff nearly 700 passengers have been placed on the no-fly list in 2020 for refusing to comply with policies requiring masks on planes.This is a sharp increase from the 460 banned passengers the airline reported in October. Delta and other airlines have been adding mask rule-breaking passengers to the no-fly list since early in the pandemic.Delta is not alone, latest numbers from United report about 430 passengers of that airline have been added to the no-fly list for not following their mask policy, and 88 have been banned from JetBlue flights.A Department of Defense study found that masks, combined with airplanes’ air filtration systems, can greatly reduce the risk of transmitting the coronavirus during a flight.While that sounds like a lot of passengers, Delta told Fox News they are flying about 1 million customers per week.In the message to staff Wednesday, Delta’s CEO Ed Bastian thanked employees for taking unpaid leave and manage reductions in hours earlier this year, which helped them be one of the few airlines that avoided involuntary furloughs. Ground workers and headquarters employees were cut to three or four days a week.However, he is now asking employees again to take unpaid leaves of absence to help the company save money, according to the staff memo. Bastian said Wednesday that Delta will need more employees to take unpaid leave “for the foreseeable future.”“I ask everyone to consider whether a voluntary leave makes sense for you and your family,” he said in a memo to employees.About 15,000 Delta employees have already left the airline through buyouts and early retirements, according to the Atlanta Journal Constitution.It's a sign of the deepening slump in air travel with coronavirus cases rising across the country. Delta expects to lose up to million a day on average during the fourth quarter.Delta is also one of the last airlines to block the middle seats on their planes, and says they will do so through March 2021.Unlike American and United, Atlanta-based Delta has avoided furloughs since the pandemic started by convincing thousands of workers to retire early or take unpaid leave.But the air travel recovery seems to be faltering. Passenger traffic rose over Thanksgiving week but has dropped since then. 2327

At least three people have died, including an alleged gunman, after gunfire erupted at a home in Port St. Lucie in southeastern Florida. Officers on scene said a chilling 911 call came in Monday afternoon, a girl said someone was inside her house shooting people.At about 1:15 p.m. ET Monday, the city’s police department advised the public to stay away from the scene on Morningside Blvd. near Morningside Elementary School. Around 3:30 p.m. ET, officers reported a man and 13-year-old girl found at the home had died. Two others found at the scene were taken to a nearby hospital. An officer was injured, and is expected to be OK. A SWAT Team then made entry into the home and found the suspected shooter dead in an upstairs bedroom. Police say it was a dispute about the alleged gunman's dog that started the incident. 830

As many people started decorating early, it's likely 2020 is a "boom" year for Christmas tree sales. Some even bought a "real" tree for the first time.In July, Bob Schaefer had a feeling it was going to be a big year for Christmas tree sales. The general manager of Oregon-based Noble Mountain Tree Farm says his company looks at the big holidays leading up to the Christmas season to get an idea of what the market will be like.“The next thing we watch is pumpkins - again, off the charts, early,” Schaefer said.Noble Mountain is a large tree producer, and it has been in the Christmas business since 1969. It now sells about half a million trees a year. Schaefer says it developed helicopter harvesting and can have your tree cut and shipped in 24 hours.“This year, we shipped to Dubai, Hong Kong, Canada, Mexico and of course the US,” Schaefer said.Christmas trees are a 10-year crop and once a farm has harvested those trees that are mature and ready, that's it for the tree.“Our sales were off the charts and we did sell out,” Schaefer said. “We’re wholesalers, we don’t sell to individual customers, but our wholesale sales were done by the first of October. Our trees were committed for sale."Schaefer said people started decorating the weekend after Halloween, leading to thriving initial sales.“If it turns out that COVID has people staying home and they have in their hearts the need for a lot of Christmas cheer, then we can provide that with a real tree,” Doug Hundley, spokesman for the National Christmas Tree Association, said.He said if you don't have your tree yet, don't worry. They won't sell out."We’ve never had a shortage. What we have now is a nice balanced, tight market between supply and demand,” Hundley said.It's no easy feat to predict the market, in fact, it's next to impossible, he said.“When we have a boom year like we may be having right now, we kind of suspected it, but we didn’t anticipate it and we can’t produce a real tree overnight,” Hundley said. “So, we have to provide what we have and hope it’ll work out.”He said if lots are empty, it's because the major tree weekends have passed.Ninety percent of people have already gotten their tree this year. Hundley says what's left will suffice for those who still need one. He hopes they all sell. If they don't, they're rendered useless.“The beauty of real trees over fake is we have a highly biodegradable product, it’s grown naturally, part of nature, benefits the environment supports the American economy and when we’re done, we can grind them so easily and chip them into mulch,” Hundley said. “They literally become soil in a couple of years, put back in the ground.”If you are purchasing a natural Christmas tree, experts recommend not adding additives. All your tree needs is plain water at any temperature. 2813

  

As someone who once criticized President Barack Obama for offering public timelines on American military engagement overseas, US President Donald Trump may have backed himself into a corner following his own promise to respond, and respond harshly, to the deadly chemical attacks in Syria.Last week he declared he wanted to withdraw US troops from Syria as soon as possible. But the suspected use of chemical weapons in Syria over the weekend may force him to reevaluate the US mission in that country.Vowing on Monday to come to a decision "over the next 24 to 48 hours" on how to make Syria pay a "big price," Trump's White House now appears to be scrambling to match its policy to his words.Trump tweeted Wednesday that missiles "are coming" in response to a threat from Russia to shoot down missiles coming into Syria.  836

  

As students return to school and employees head back to the office all with new safety protocols likely including wearing a mask, a new study from Duke University explores which masks are more effective.Spoiler alert: A fitted N95 mask, usually reserved for those in the medical community, performed the best in their test. However, since many Americans do not have access to those and have been using a mix of store-bought or homemade cotton and fabric facial coverings, Duke tested 13 other kinds of masks.The study, which was published Friday, was prompted when a professor at Duke’s School of Medicine was asked to assist a local group buying masks in bulk for the community. According to CNN, the professor wanted to make sure the masks they bought were effective.Researchers gathered 14 kinds of masks, including the professionally-fitted N95 mask, a bandana, homemade cotton varieties, and a surgical mask. They then used a dark room, laser beam and cell phone camera to record how many droplets (which reflect the laser beam light) each mask allows through.For each mask test and the non-mask wearing control test, the speaker was recorded saying “Stay healthy, people” five times. Each mask was tested ten times. 1229
