American Airlines is taking its long-grounded Boeing 737 Max jets out of storage, updating key flight-control software, and flying the planes in preparation for the first flights with paying passengers later this month.The airline invited press reporters and photographers on board one of the planes Wednesday to demonstrate its confidence in the plane’s safety.All Max jets worldwide were grounded in March 2019 after the second of two crashes that together killed 346 people. Last month, the Federal Aviation Administration approved changes — mainly in flight-control software — that will allow airlines to resume flying the plane.American flew journalists from Dallas to the airline’s maintenance center in Tulsa, Oklahoma, where crews explained how they are bringing the planes out of storage and making FAA-required changes.American is likely to be the first carrier to put passengers on Max jets, beginning Dec. 29 with once-a-day round trips between New York and Miami. In the meantime, the airline plans flights with employees on board.Some relatives of people who died in the crashes — and who still believe the plane is unsafe — expressed outrage at both Boeing and American over what they termed a publicity stunt.Zipporah Kuria, a British citizen whose father died in the second Max crash, said Boeing and the FAA should instead turn over documents on changes made to fix the plane and how they were tested. The company has withheld the documents, saying they cover trade secrets.“I feel like Boeing is using the press to leverage public trust instead of actually genuinely earning public trust,” she said. “I’m really disgusted by the whole thing and the fact that American Airlines would pay for that. Their focus is more about the profit and corporate interest than it is about consumer safety.”Some people who lost family members believe that the FAA erred by not accepting all the recommendations made by pilots and aviation professionals during a public comment period on its proposal to let the plane fly again.Scrutiny of the plane has focused on a flight-control system called MCAS, which repeatedly pushed down the nose of the plane before both crashes. Boeing, which describes changes to the plane on its website, and the FAA say the system has been made less powerful and easier for pilots to override.Some of the family members, however, wanted a deeper, nose-to-tail review of the plane. And they don’t trust Boeing or the FAA, which allowed the plane to keep flying after the first crash, in Indonesia in 2018.“It hasn’t been evaluated to the point where we can say that it’s safe,” said Nadia Milleron, whose daughter was killed in the second crash, which occurred in Ethiopia. “This plane hasn’t flown very much with this new software, the revamped MCAS, interfacing with the plane. It’s not responsible for them to put you on this flight.”Chicago-based Boeing said Wednesday it has flown more than 1,400 test flights on updated Max planes. The FAA said its people put in 60,000 hours reviewing and testing Boeing’s work.American is likely to be the only U.S. carrier using the Max for several weeks. United Airlines expects to put the plane back in its schedule during the first quarter of next year, with Southwest following in the second quarter. Regulators in Europe and Brazil have cleared a path for their airlines to resume Max flights in a few weeks.It’s unclear whether the flying public will accept the plane or avoid it. Some industry officials believe that fear of getting on the plane has lessened with time. American says that if customers don’t want to fly on a Max, it will have the flexibility to put them on other planes.___David Koenig can be reached at www.twitter.com/airlinewriter 3739

Anyone could have predicted that Stephen Colbert's opening Emmy monologue would include talk of politics and mentions of President Donald Trump, but no would could have predicted a surprise cameo from White House alum Sean Spicer.The former White House press secretary made a brief appearance at the end of Colbert's opening monologue for a bit that appeared to mock Spicer's defense of Trump's inauguration attendance.PHOTOS: Celebs at the 2017 EmmysOn stage, Colbert asked if someone could predict how large this year's Emmy audience would be -- Spicer's cue to emerge from backstage."This will be the largest audience to witness the Emmys, period -- both in person and around the world," Spicer said from a podium.Spicer battled with reporters back in January as he defended the size of the crowd that showed up to watch Trump's inauguration. At the time, he said, "This was the largest audience to ever witness an inauguration, period," despite photographic evidence to the contrary.Colbert also joked that HBO's Emmy-nominated Bernie Madoff TV movie "Wizard of Lies" was "the Sean Spicer story." Spicer's appearance drew reactions of shock from the celebrity audience."Melissa McCarthy everybody. Give it up," Colbert said, joking, as the camera panned to McCarthy, who famously impersonated Spicer on last season's "Saturday Night Live."The-CNN-Wire 1363

Approximately 44 million turkeys were Thanksgiving dinner in the United States last year, but on Tuesday at the White House, one lucky bird is going to be spared a similar fate.President Donald Trump will participate in the time-honored tradition of the turkey pardon, granting clemency to a bird in the White House Rose Garden before jetting off to Mar-a-Lago for a long holiday weekend.Hailing from South Dakota, this year's pardon contestants are Peas and Carrots. The poultry pair's journey to Washington was a veritable gravy train.Presidential turkeys are raised separately from their soon-to-be-stuffed counterparts, according to the South Dakota Soybean Research and Promotion Council.Per the council, Peas and Carrots lived in their own house away from the other turkeys and were handled regularly to "get used to people and activity," as it is important that they wouldn't be in a fowl mood for their big day.Weighing in at 39 and 41 pounds, respectively, Peas and Carrots hatched in late June of this year. Since then, the fluffy duo has developed a social media presence, knowing the importance of appealing to the baste. 1141

Are masks complicating facial recognition software? The short answer is no, but masks do complicate matters.Computer science experts say that face coverings and other accessories may act as a speedbump, but it wouldn’t be very difficult for the software to be modified.However, with a face covering, recognition may be less accurate.“It has fewer data points and that is the concern,” Steve Beaty, computer science professor at Metro State University-Denver, said. “Because you are essentially removing your nose and your mouth from the equation if you will, there will be fewer data points and the concern is that other people can authenticate as you.”Before the use of face masks, facial recognition software had an inaccuracy rate of less than 1 percent. Now, the National Institute of Standards and Technology estimates that the inaccuracy rate has increased from 5 to 20 percent. 892
