Boeing's bestselling passenger jet is facing increased scrutiny after being involved in two deadly crashes in less than five months, a situation that threatens to tarnish the US plane maker's reputation for safety.Chinese aviation authorities on Monday told airlines in the country to ground all their Boeing 737 MAX 8 aircraft, citing the need for "strict control of safety risks." Some individual airlines are taking similar action elsewhere. And Boeing has postponed the debut of its new 777X jetliner, which was scheduled for this week, as it deals with the fallout from Sunday's disaster in Ethiopia.The flurry of negative headlines unsettled investors. Boeing shares dropped nearly 9% in premarket trading early Monday in New York.All 157 people on board a 737 MAX 8 operated by Ethiopian Airlines were killed when the plane crashed shortly after takeoff on Sunday morning. In late October, a 737 MAX 8 flown by Lion Air went down off the coast of Indonesia, killing 189 people.Both the Ethiopian Airlines and Lion Air planes were brand-new aircraft. And both crashed minutes into flight.Ethiopian Airlines said Monday that it was grounding its fleet of 737 MAX planes as an "extra safety precaution," and Cayman Airways, the main carrier of the Cayman Islands, said it would do the same until "more information is received."The circumstances of the two crashes remain under investigation, and Boeing has presented no evidence to suggest the two disasters are linked. The similarities may be a coincidence."A formal investigation will need to be conducted into this new crash. It's important not to speculate as to its causes. A final, conclusive report has yet to be issued in the case of the Lion [Air] crash," said Greg Waldron, Asia managing editor at aviation research firm FlightGlobal."That said, having two crashes of a brand new type in a short time is an unprecedented state of events," he added. "It is inevitable that this will affect perceptions about the 737 MAX family."The decision by Chinese authorities to ground 737 MAX 8 planes in the country is a serious blow."A suspension in China is very significant, as this is a major market for Boeing," Waldron said. Chinese airlines have 97 of the 737 MAX aircraft in service, more than a quarter of the total in operation worldwide, according to FlightGlobal.Boeing's bestsellerThe single-aisle Boeing 737 has been a workhorse on short- and medium-haul flights for decades. The 737 MAX is the latest version — and the company's bestselling aircraft by far. Airlines have ordered thousands of them.The two-year-old 737 MAX 8 model in particular is hugely popular (the MAX 9 only recently went on sale and Boeing has not yet delivered the MAX 10). Last year, 72% of Boeing's deliveries were 737 planes. Boeing plans to make 59 new 737s each month this year — more than four times the number of 787s, Boeing's next-best seller.Southwest Airlines has the largest fleet of 737 MAX 8 airplanes, followed by RyanAir and FlyDubai, according to 3018

 Las Vegas is one step closer to having a high-speed train between the Las Vegas Strip and California. On Tuesday, Las Vegas city and economic leaders at the Nevada Economic Development Conference talked about the railroad service that would connect more than 22 million people. Talks of a rail service date back to the late 90s, but Virgin Trains USA says it's now ready to move forward because its current routes in Florida have been a success and it has a model to follow. "We're looking to start construction in 2020," says Bob O’Malley the vice president for Virgin Trains USA.RELATED: 619

Online interaction with one another has gotten to the point where websites and apps are having to remind us how to act. The neighborhood app Nextdoor has gotten a reputation for sometimes strange posts that can prompt mean and off-color responses.There's a whole Twitter account dedicated to examples. Now, Nextdoor has rolled out a new feature to try and keep some civility online. It's called a "Kindness Reminder." If you try and post a response that's similar to one that's been flagged in the past, you'll get a reminder of the community guidelines and that they can change your response. But you can still post what you want. “One of the problems of the age we're living in is that people don't necessarily share a common understanding of what counts as civil interaction,” said Keith Bybee, a professor of law and political science at Syracuse University.Bybee says some people are strategically not civil or just plain rude in order to attract attention. You see it in politics and trolling behavior. But in the end, civility benefits everyone. “Civility is sort of the lubricant that makes social interaction possible,” Bybee said. “It allows us to live in a diverse, heterogeneous society but nonetheless coordinate our actions for common purposes, so it’s important to find a way to get along with strangers.”Ultimately, you have to care what the other person thinks of you to achieve civility. 1418

DENVER -- The community is rallying around a downtown shoeshiner whose business hasn’t been the same since the pandemic began.When the pandemic hit back in March, Downtown Denver started to look like a ghost town, but one man was still showing up for work every day."A shoeshiner is based on four categories: wisdom, knowledge, art and pride," Claude Thompson said. "I want my members to know I will always be there for them rain, snow, shine, it doesn’t matter."Thompson has been calling the 16th Street Mall his office for over two decades. Shining the shoes of tourists, locals, business people, and even mayors."If you are in the business world, your shoes and boots should represent your job; you go to work with a dirty shoe on, you are not going to close the deal," Thompson said.The fast-talking comedian is somewhat of a local celebrity in the area."I keep my shoes so waterproofed I believe they can walk on water," Thompson joked.He charges for shoes for boots and for a lifetime membership."He gives ya hell on your shoes," lifetime member Jason Kuzov said. "He’s funny and brightens up your day."Claude’s smile began to fade as people started to work from home. Some days he only gets one or two shines.REV Energy Services and several of Thompson's customers in the oil and gas industry started a GoFundMe to help."It will help Claude so he can keep paying his rent and buying food; we don’t know when the customers are going to come back for him," Kuzov said.You can help Claude by stopping by 16th and Welton for a shoeshine."I’m not in it for the money, I am in it to help save his sole," Thompson said.
