The United States is the last country to allow flights of the Boeing 737 MAX fleet after at least 47 countries and multiple airlines grounded the aircraft following Sunday's Ethiopian Airlines crash.At least 271 of the 371 MAX planes in service were grounded, according to CNN calculations. To date, 385 MAX aircraft have been delivered, according to Flight Global, of which 344 are the MAX 8 variant.On Wednesday, Canada joined Egypt, Hong Kong, Lebanon and New Zealand in banning all Boeing MAX aircraft from their airspace as an extra safety precaution, joining scores of nations, carriers and authorities that have temporarily suspended the MAX 8 model or other models in the range.On Wednesday afternoon, Canada's Minister of Transport Marc Garneau said that as the result of new data that they received in the morning, they will no longer allow the Boeing 737 MAX 8 or 9 aircraft to take off or land in Canada, nor will they allow aircraft to fly over Canadian airspace.Six minutes after takeoff, Ethiopian Airlines Flight 302 plummeted into a field, killing all 157 people on board. Shortly after leaving Addis Ababa's Bole International Airport, the pilot reported flight control problems and asked to return to the base.As investigators search for clues into the cause of the disaster, some aviation experts are drawing parallels to the Lion Air Boeing MAX 8 plane that went down last October over the Java Sea in Indonesia, killing all 189 people on board.Both Boeing and the US Federal Aviation Administration (FAA) have said they have no plans to ground the aircraft.The US and Canada are the only countries with MAX 8 flights still allowing the jets to fly. US carriers including American Airlines, Southwest Airlines and United Airlines are flying MAX 8 planes; Air Canada is also continuing to fly its MAX 8 fleet.The MAX 9 model has never crashed, but it was included in an FAA emergency airworthiness directive following the Lion Air crash last year. A MAX 10 model is still in development.China's aviation administration was the first to order a suspension on Monday evening, grounding all domestic Boeing 737 MAX 8 jets, citing its principle of "zero tolerance for safety hazards."China has one of the world's largest fleets of Boeing 737 MAX 8s, operating 97 of the planes, according to Chinese state-run media.The fall-out for Boeing and its future in China could be severe for investors: China is predicted to soon to become the world's first trillion-dollar market for jets.In a statement, Boeing said it continued to have "full confidence" in the safety of the 737 MAX 8 aircraft, but said it understands the decisions made by customers.On its official Twitter account, the company also reiterated that safety remains its priority.Daniel K. Elwell, the acting administrator of the FAA, said it has conducted a review of the Boeing 737 MAX 8 and found "no basis" to ground the aircraft.As more nations ban the 737 MAX 8 planes, Boeing's stock continues a steep slide.Shares in Boeing are more than 10% lower than at Friday's close.As the Ethiopian Airlines and Lion Air crashes are still under investigation, there is no evidence that they had a common cause.The black boxes from the Ethiopian Airlines plane were recovered on Monday, which will enable investigators to learn more about the cause of the crash. On Wednesday, Ethiopian Airlines spokesman Asrat Begashaw told CNN the "black box" data recorders recovered will "definitely be going to Europe," as Ethiopia does not have the necessary equipment to analyze that data.Begashaw said they haven't decided which country the black boxes will go to yet.In the meantime, some aviation experts are focusing on the similarities between the two incidents."Given in both air crashes, the aircrafts were newly delivered Boeing 737 MAX 8, and both accidents occurred during the take-off, they share certain similarities," the Chinese administration said in a statement.Ethiopian Airlines CEO Tewolde GebreMariam told CNN on Tuesday that the company's pilots had received additional training on the flight procedures involving the 737 MAX 8 after the Lion Air crash."We believe the similarities are substantial" between the two crashes, GebreMariam said, adding that both incidents featured new models of the same airplane, and both flights lasted only minutes before the planes went down."We don't yet know the exact cause of the accident, and speculation is not helpful in either way," GebreMariam said, "but I think there are questions without answers on the airplane."Still, aviation safety experts and regulators around the world remain divided on whether the Boeing 737 MAX 8 is safe."I've never said that it's unsafe to fly a particular model of aircraft, but in this case, I'm going to have to go there," David Soucie, a former FAA safety inspector, told CNN, saying passengers don't have enough information.Peter Goelz, a former managing director of the National Transportation Safety Board, said he believes it's too early for American authorities to ground the jets.Some pilots agree. The pilots union at Southwest Airlines, which has the largest fleet of MAX 8s still flying, has stood by the airline's decision.In a Southwest Airlines Pilot Association letter, union president Jonathan Weaks said the union is "extremely confident" that the 737 MAX is safe.He added that he would put his family, friends and loved ones on any Southwest flight, but that he has lobbied for training to "evolve and improve."The letter warns, however, that if new information comes to light, the union "will not hesitate to hold any organization or person accountable." 5654

There are a lot of myths circulating about COVID-19, the disease caused by the new coronavirus. Let's break the facts.The Centers for Disease Control and Prevention (CDC) says symptoms of COVID-19 include fever, coughing and shortness of breath. Symptoms can appear two and 14 days after exposure.Doctors draw comparisons to the flu.“Coronavirus is also interesting because it doesn't seem to be quite as infectious as common influenza,” said Dr. Shauna Gulley.Dr. Gulley with the large health system Centura Health has worked with coronavirus patients during this outbreak."Many of those people are quite well and have very minimal symptoms and do not need additional interaction with the health care system,” said Dr. Gulley. "We do believe in people that are, perhaps, older or have multiple medical problems such as diabetes or anything that makes your immune system weaker, that coronavirus may be more dangerous than influenza.”Dr. Gulley says it’s still unclear why coronavirus has been mild in children. She has advice on what people should do. "First of all, the worry about going and getting toilet paper, I don't think that should be first and foremost on anyone's list today,” said Dr. Gulley. While it’s important to be prepared, it’s important to not go overboard."We are seeing people come into our environments and take soap, masks and other supplies home to try to stockpile that in their homes,” Dr. Gulley said. "One of our hospitals actually had all of their soaps and hand sanitizers stolen last week."She also says people need to know how to use hand sanitizer."The myths around putting it on your body or on your face is where we get into trouble. Those things are not safe for people to do,” said Dr. Gulley. The CDC says people at a higher risk should avoid crowds. Dr. Gulley says it’s a good idea to keep your space."We believe that staying about six feet away from somebody with symptoms is the most protective space,” Dr. Gulley said.As the number of cases grows in the United States, public anxiety may be growing with it. So, don’t fear communicating if you’re dealing with another kind of medical issue.“If you're an allergy sufferer, I think it's important for you to talk to others about the fact that you have allergies and for them to be a little bit more assured that you're not infected. You have no fever, you have no deep cough and you have no risk factors for coronavirus,” Dr. Gulley said.If you are experiencing symptoms, call your doctor. 2494

Transportation Security Administration (TSA) employees are one group who are expected to work without pay during the shutdown. Now, some of them have been choosing not to come in by calling in sick. Brian Turner, a TSA agent, and his wife are new parents. Thanks to the government shutdown, Turner has no idea when he'll get his next paycheck, and the couple is worried they could run out of money by the end of the month. “We are a paycheck to paycheck family, in the reality of it,” Turner says. “So, we do depend on that constant income.” Turner is considered an essential employee, so he still has to work even though he's not currently getting paid.“When you don't have a paycheck coming in and you don't have a guaranteed source of income when you thought you did, it's disheartening and it kind of makes you feel a little panicked,” he says.For some TSA agents, the shutdown is taking its toll. A growing number of agents are now calling out sick to work other places or to find new jobs. Safety and long lines could become another concern if the shutdown continues. “Poor morale or other issues that could affect the TSA because of the shutdown and not getting paid, that could have some sort of intangible effect on how well they're doing their jobs,” says David Inserra, with the Heritage Foundation. “People are people, and if you're not getting paid, if you're upset, you're probably not going to be doing as good of a job as you otherwise would.” For now, Turner is still going to work. He hopes Congress and President Trump do the same and find a shutdown solution. “You feel hopeless and you feel helpless,” Turner expresses. “I'm not in Washington. I don't have the influence these people of power have, and we rely on them. We elect them to these positions to get a job done.” 1807
