FRANKFURT, Germany (AP) — Air travel will take even longer than previously thought to return to pre-virus levels. That's the gloomy prediction from the air transport trade association or IATA. They are pushing their forecast back by a year, to 2024. That's when they say travel will make it back to 2019 levels. "A slower recovery will put more airlines in financial peril," a release from the trade association stated. "And, as we have said many times in these briefings, government relief measures are essential."In June, air travel around the world was down 86% compared to a year earlier. IATA says air travel recovery will take longer because of the resurgence of cases in many places including the U.S. 716

FRESNO, Calif. (AP) — An elementary school superintendent in Central California says he allowed a janitor to wear a mask and carry a fake gun during an active shooter drill to "make sure this was realistic."A teacher told KSEE-TV that the drill, which happened at Raisin City Elementary School before the summer break, went too far.Kim Copper said the masked gunman pounded on her classroom door and tried to open it as she huddled in a corner with terrified students.School Superintendent Juan Sandoval admitted teachers and students were not told about the janitor's role. He said active shooter drills have become routine and he wanted students to understand the gravity of the situation.A school board official told the station the school will improve its active shooter training procedure. 802

Former Vice President Joe Biden came out ahead in Thursday's duel of town halls with President Donald Trump — at least in terms of TV ratings.According to The Associated Press, Biden garnered 14.1 million viewers on ABC between 8 p.m. ET and 9 p.m. ET on Thursday night. During that same time span, Trump drew a total of 13.5 million viewers during his hour-long event on NBC. These numbers include ratings for both network and cable audiences, who could have watched the president's event on CNBC or MSNBC. Biden's event was only broadcast on ABC on TV. Trump and Biden were originally slated to appear together for a town hall-style debate. However, the Commission on Presidential Debates said earlier this month that the event would take place virtually following Trump's COVID-19 diagnosis. Trump then dropped out, saying he wouldn't "waste his time" with a virtual debate.Biden then scheduled his town hall event with ABC News. It wasn't until Wednesday that NBC News announced Trump would hold his own town hall at the same time as Biden. 1052

For the third time in three weeks, a major commercial airline flight was diverted mid-air because of a damaged window.The latest incident happened Sunday, when a JetBlue flight from San Juan, Puerto Rico, to Tampa, Florida, was diverted because of damage to the plane's windscreen.The airline said the flight was diverted to Fort Lauderdale out of "an abundance of caution following a report of damage to one of the outer layers of the cockpit windscreen." The plane landed safely and the passengers were accommodated on another aircraft, JetBlue said.That incident comes about three weeks after a?fatal Southwest Airlines flight in which a jet engine failed midair and debris knocked out a cabin window.Jennifer Riordan, a philanthropist and Wells Fargo executive in New Mexico, was partially sucked out of the plane as other passengers struggled to pull her back into her seat. She was later pronounced dead from blunt impact trauma, a spokesman for the Philadelphia Department of Public Health said.Investigators with the National Transportation Safety Board who looked into the failure said that one of the engine's 24 fan blades was missing.Despite the mid-air engine failure, Captain Tammie Jo Shults was able to safely pilot the flight in an emergency landing in Philadelphia.On May 2, a Southwest Airlines flight from Chicago to Newark, New Jersey, made an unplanned landing after a window cracked.Flight 957 landed safely at Cleveland Hopkins International Airport, FAA spokeswoman Elizabeth Cory said. Southwest said the diversion was in response to a reported crack in the outer pane of a multi-pane window.Passenger Linda Holley texted her son Ryan with a picture of a damaged window."Window on plane cracked during flight. Landing in Cleveland to be safe. Everything ok but scary," one of her texts read.In another, she said: "Yes Southwest. Just heard loud noise. Very large crack with piece of window missing at bottom. Just landed. Everything ok. Don't know plan yet."There was no depressurization in the cabin and oxygen masks were not deployed. 2085

For months now, public health experts and educators have been lamenting the long-term impacts of remote learning.In May, researchers estimated that by the beginning of this academic year, the average student would lose a third of their reading progress and half of their math progress from the previous year.“That was kind of assuming kind of a worst-case scenario,” said Beth Tarasawa, executive vice president of Research at NWEA, a nonprofit standardized testing company that released its findings from this fall’s assessment.“Kids remarkably have weathered pretty well in reading and those patterns both in the cross-sectional as well as the longitudinal studies really kind of highlight some good news,” said Tarasawa.But their analysis of data from nearly 4.4 million U.S. students in grades 3-8 found average scores for math were lower – between 5 and 10 percentile points– for students this year as compared to same-grade students last year.The findings represent some of the first empirical measures of how the pandemic has affected student performance.“We're moving slower, which means that we're covering less material over a certain period of time,” said fifth grade teacher Cara Koen.Koen, who has been teaching reading and math for more than two decades, says remote learning has forced her to slow her pace, especially with math.“There may be difficulties with Wi-Fi and different things from day to day” said Koen. “You have to slow down in order to reach all learners.”Kimberly Berens is a child development expert, educator and the author of "Blind Spots: Why Students Fail and The Science That Can Save Them."“Spending more time on repeated reinforced practice of skills to mastery so that when kids have gaps in instruction that are inevitably going to happen from school closures, kids getting sick or pandemics then kids will be more resilient,” said Berens.Still, NWEA’s data set is incomplete. One in four students who they tested in 2019 were missing from this year’s assessment.“They were much more likely to be African-American or LatinX or Hispanic,” said Tarasawa. "They were more likely to be from high poverty schools and they were more likely to be lower achieving in the first place.”That means that while the new data suggests some promising outcomes, we still don’t know just how severely the pandemic is impacting minority and socio-economically disadvantaged students. 2413
