Twana Wilson received an Amazon Echo Dot as a gift from her husband a few months back. He thought she would enjoy having Alexa play music and read her the weather forecast, but the Echo still sits in its original box. She won't use it.Why not? Because like so many people, Wilson suspects Amazon is watching her, even listening to her conversations through her phone and laptop. "I just can't get myself to do it yet," Wilson said. "I am not ready for it."She has her reasons. She was recently chatting with a friend who was flying to Paris. "The next day," Wilson said, "I had a targeted ad for booking flights to Paris." She said she had never done any web searches and had no plans for a trip to Europe.A week or so later, she says, she was talking with her husband about his Jeep. "Afterward I started having a stream of Jeep ads" she said.She said it's the same story if she ever discusses a product with friends via text messages. "I even get emails form Amazon saying, 'Hey, aren't you looking for this?' Actually I wasn’t," Wilson said.Like many other Amazon Prime members, Wilson is caught between the convenience of one-click everything and concerns about her privacy. Recent news reports that 1217

Two flight data recorders from Ethiopian Airlines Flight ET302 have been found, as airlines around the world ground Boeing 737 MAX 8s like the one which crashed Sunday, killing all 157 people on board.The plane's Digital Flight Data Recorder (DFDR) and Cockpit Voice Recorder (CVR) were recovered from the wreckage Monday, Ethiopian Airlines said in a statement. They will enable investigators and experts piece together the last moments of the flight, and should help explain why the new plane crashed.Flight ET302 to Nairobi had just taken off from the Ethiopian capital of Addis Ababa Sunday when it reported technical problems and asked for permission to turn back. It crashed shortly after.With investigations underway, multiple countries have suspended use of Boeing's new 737 MAX 8 aircraft amid concerns about its safety.On Monday, The Civil Aviation Administration of China ordered that all domestic Boeing 737 MAX 8 jets be out of the air by 6 p.m. local time, due to its principle of "zero tolerance for safety hazards."China has one of the world's largest fleets of Boeing 737 MAX 8, operating 97 of the planes, according to China's state-run media.The move was followed by an announcement from Ethiopian Airlines that the carrier had grounded its fleet of Boeing 737 MAX 8 jets as an "extra safety precaution." Cayman Airways also said on Monday it was grounding both of its "new Boeing 737 MAX 8 aircraft ... until more information is received."Sunday marked the second time in less than six months that a new Boeing aircraft had crashed just minutes into a flight. A Lion Air Boeing 737 MAX 8 flight went down over the Java Sea in last October, killing all 189 people on board.Both crashes are under investigation. There is no evidence of a link between the two, but similarities in the incidents have prompted caution among some airlines."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. It added that it would contact Boeing and the US Federal Aviation Administration to confirm "flight safety" issues before allowing the planes to fly again.Mary Schiavo, a CNN aviation analyst and the former Inspector General of the US Transportation Department, called the two incidents "highly suspicious.""Here we have a brand-new aircraft that's gone down twice in a year. That rings alarm bells in the aviation industry, because that just doesn't happen," she said.State-owned Ethiopian Airlines is one of Africa's leading aviation groups, and the continent's largest carrier by number of passengers.The Kenyan and Ethiopian governments announced a joint disaster response team on Monday to investigate the crash. Kenya's Cabinet Secretary of Transport James Macharia described it as a "very complex investigation."In a statement Sunday, Boeing said it was 2940

Two agents with the North Carolina State Bureau of Investigation's Bomb Squad were injured, one critically, in an explosion Friday morning in an eastern county, the SBI said.Jimmy Tyndall, 33, is in custody, Sampson County Sheriff Jimmy Thornton told reporters. The explosives had been found in a car Tyndall was driving and at his residence, Thornton said.Agents Timothy Luper and Brian Joy had been called in to help after Sampson County deputies found homemade bombs and bomb-making materials in a search after a traffic stop Thursday afternoon. The explosion happened as the agents were working to dispose of the material, the SBI said in a statement.Deputies on Thursday stopped Tyndall's vehicle and found pipe bombs during a search, Thornton said. The sheriff said he thought the driver had been stopped for speeding, but then the officers noticed the explosives."Once they began looking, the devices were readily seen," Thornton said. "At that point, then everybody backed away and did nothing else until the SBI bomb squad arrived."Two bombs were found in the vehicle. That led to a search of Tyndall's residence, where three more were found, according to Thornton."I don't think his (Tyndall's) intention was to blow anything up," Thornton said. "I think it was just one of those things he got off on."Joy was airlifted to a burn center in Chapel Hill for treatment and is in critical condition, the SBI said.Officials on Friday said state and federal agents were at the residence to investigate and dispose of any bomb-making materials. "As a result, explosions may be heard during this time," the SBI said. 1630
