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
DENVER, Colorado — More than half a million students throughout the Front Range will go back to school Thursday, after more than a hundred schools and districts were forced to cancel classes Wednesday in response to a credible threat allegedly made by a Florida woman whom authorities said was 307

In an instant, the windshield to Rob Weber's small airplane shattered while a thousand feet in the air. “I was pretty much on the edge of blacking out,” he describes. A camera in the cockpit captured it all. When you slow down the video, you can see a bird fly right through the windshield, forcing Weber to declare an emergency as he approached the airport in Fort Myers, Florida. “After I’d taken the hit to the head, I was really dazed,” Weber recalls. “I was having a hard time communicating with them, because I was knocked silly. I really couldn't focus on where I was or what was going on.” The latest data shows there are a record number of bird strikes involving planes, with more than 40 a day on average. A big reason for the spike: more flights and a jump in the bird population. “It's a classic probability situation. More planes and more large birds in the air at the same time,” explains Michael Begier with the National Bird Strike Committee. Begier works with the organization to track incidents and find ways to reduce them. Statistically speaking, the highest chances of being involved in bird strike are from July through October, during the day and while approaching the airport. The accident involving US Airways Flight 1549, known as the Miracle on the Hudson, is perhaps the most memorable and extreme example of how damaging bird strikes can be. However, the majority of bird strikes do not cause any major damage to planes. “The percentage of damaging strikes has actually been going down in the airport environment and that's where it's most vulnerable,” Begier says.For years, workers have used loud noises and fireworks at airports to scare off birds, but they have started testing new ideas, including using drones that look like large predatory birds and redesigning the lights on airplanes to deter birds. 1851
A Southern Arizona school district is taking a creative approach to better sanitize the classroom daily.Santa Cruz Valley School District bought six Power Breezers that will disinfect a classroom in 20 minutes.Superintendent David Verdugo said the school district did this as a cost effective way to provide extra safety and security to students and staff.He said it will be used after school to clean empty classrooms, hallways and even school buses.Each unit costs about 4,500 dollars."This is an opportunity for them to look at a way to sanitize a room in a short period of time and utilize their staff but also be cost effective," Superintendent Verdugo said.He said the district is also requiring all students to wear masks, have their temperature checked, and social distance in and out of the classroom.Every classroom will only be at 50% capacity, meaning 15 desks per room, he said. In order to do this, the district came up with a hybrid approach to learning."There will be a group A and a group B," Superintendent Verdugo said. "The group A students will be on Monday. They will come to school, have their direct instruction and then they will be at home the next day. Then, group B will come to school, but they will still have some interaction that day with assignments and virtual opportunities."He said the district is planning on starting remote learning on August 3 and then the hybrid approach will being on August 31. KGUN's Veronika Vernachio was first to report this story. 1517

A Twitter account providing updates on protests going on around the city said that the protest was asking for justice for Daniel Prude, a Black man who died March 30 after he was taken off life support, seven days after the encounter with police in Rochester. His death received no public attention until Wednesday, when his family released police body camera video they obtained. Prude was handcuffed, hooded and pinned down by police.Seven officers involved in the incident were suspended Thursday by Rochester Mayor Lovely Ann Warren. The incident caught the attention of State Sen. Brad Hoylman, who represents Manhattan. This is incredibly disturbing. My staff is reaching out to the city. https://t.co/jE54kA8R9O— Senator Brad Hoylman (@bradhoylman) September 4, 2020 No injuries have been reported. The NYPD tweeted out that it was investigating and said that the car was not an NYPD vehicle. There is an ongoing investigation into an incident in Times Square involving a black Taurus sedan.
