The plane behind Lion Air's crash off Indonesia was one of Boeing's newest and most advanced jets. It was just two months old and with 800 hours under its belt, so experts are baffled as to what exactly caused the 737 MAX 8 to crash.While no information has been released yet as to why the brand-new plane crashed into the sea 13 minutes after takeoff,?FlightRadar24 has published data that shows the plane behaving erratically during takeoff. When a plane would normally be ascending in the first few minutes of flight, the Lion Air jet experienced a 726-foot drop over 21 seconds.Aviation expert Philip Butterworth-Hayes told CNN that the data was unusual -- especially since takeoffs like this are typically controlled by the plane's automatic systems."This doesn't fit an automatic flight profile," Butterworth-Hayes said while studying the data. "Unless, the aircraft was trying to correct itself at the time for a number of reasons.""This shows an unusually unstable vertical flight profile," he added."Exactly at the same time as the speed increased there was an altitude dip, which meant that at that point there was quite some loss of control."The plane, which has only been in operation since August 15, was carrying 181 passengers as well as six cabin crew members and two pilots, bound for Pangkal Pinang on the Indonesian island of Bangka.Former US National Transportation Safety Board air crash investigator and CNN aviation analyst Peter Goelz told CNN the data clearly showed issues with both the speed and altitude of the plane."There is something obviously wrong in both the air speed and the altitude which would point to the flight control systems," he said. "These are fly-by-wire systems -- highly automated -- and pilots may not be able to troubleshoot failures in a timely manner." 1818

The pandemic has exposed a long-standing problem across the county: a lack of internet access in homes. And for most families, the switch to virtual learning came without warning. "Yes, there was an announcement, and my initial thought was not fear, more of daunting. I was overwhelmed," said San Diego mother Paula Gosswiller. Because for Gosswiller, it meant having to convert her kitchen into a classroom for five. Ranging from ages 5 to 13, all of her school-aged kids are in different grades."We did not have internet at the time in our house, and just the thought of homeschooling without internet or technology was daunting," said Gosswiller.The kids attend St. Ritas Catholic School in southeast San Diego, which was able to secure enough devices for each student before the school year, thanks to a donation. When school went virtual, they deployed the iPads and Chromebooks to students in need."The inconsistency of internet and things like that, really made it challenging for a lot of our families," said Principal Gina Olsen. Olsen says nearly half of the students needed to borrow a device when the school went virtual. She says they were also grateful to receive a grant from the Southeastern San Diego COVID-19 Rapid Response Fund, to help cover missed tuition payments for students. Like many families, the Gosswiller's were forced to add an internet bill to their list of expenses, but not all can afford to do this."I think the statistics are something like 1 in 4 kids in the U.S. don't have access to WiFi at home. Before the pandemic, they could stay after school, they could go to a library, maybe a McDonald's parking lot or a Starbucks," said Angela Baker, who runs corporate responsibility at Qualcomm.Located in San Diego, the tech giant Qualcomm helped turned our cellphones into smartphones with its modem chips. Now, they're putting some of that technology into computers."With people getting so used to their smartphones, and the experience of always being on, great battery life, being able to use it anywhere you are, no matter where you are, we kind of took that concept and applied it to the PC market," said Pete Lancia, who runs external communications at Qualcomm. With help from manufacturing partners, Qualcomm built computers with cellular connectivity that don't require WiFi to get online. They donated 900 to students in the San Diego Unified School District."We really need to make sure that kids have access to broadband at speeds that will let them do their homework, watch videos, see the instruction if that's being done, now that we know so many schools are probably going to be online," said Baker. And like your smartphone, the battery is designed to last all day. "I think this was a wake-up call for everyone," said Gosswiller.She says her family is making it work, navigating the challenges as they go."We're ready to take it on and mark the days off the calendar when they can go back to school physically," she said. 2981

The New York State Department of Taxation and Finance has issued a subpoena to Michael Cohen as part of its ongoing probe into whether the Trump Foundation violated New York tax laws, a department spokesman confirmed to CNN.This probe is separate from the New York attorney general's lawsuit against the Trump Foundation. The Tax Department is not able to bring any criminal charges, and if it finds any wrongdoing, the department would have to refer it to the New York attorney general's office or another prosecutor's office."A subpoena has been issued to Michael Cohen for relevant information in light of the public disclosures made yesterday," said Tax Department spokesperson John Gazzale in a statement. "We will be working with the New York Attorney General and the Manhattan district attorney as appropriate. We can't comment further on this investigation." 874

The House has passed a .3 trillion spending package that will increase funding for the military and domestic spending and will keep the government funded through the end of September.The legislation passed with Democrats and Republicans coming together to pass it less than 24 hours after the 2,300-page bill was made public.Now, it's up to the Senate to pass it before the government runs out of money Friday at midnight. The Senate need unanimous consent -- meaning all members have to agree -- to bring the bill up for a timely vote. If one member objects, it could force the government into a brief shutdown. 622
