One resident in Sarpy County, Nebraska, reported several drones flying in unison last week."Most interesting part is that the drones were flying in the night. People don't know what they are doing there. No feedback from federal agencies, local government and no one really knows what's going on there," said Victor Huang, an assistant professor at the Aviation Institute at the University of Nebraska Omaha.Drones are complex and extremely advanced. They can be used for for film making, emergency services and agricultural monitoring."The drone, similar to our computer systems, it can really do a lot of things. To me, the only limitation is your imagination," Huang said.But no one, not even the Federal Aviation Administration, knows what these drones are doing except that they're flying in a pattern, they're large and there's many of them."They don't know if it's illegal or not because right now there's no way of knowing what is up there," KMTV pilot Justin Enos said.Based on flight patterns and altitude, experts believe it could be some sort of agricultural monitoring. Regardless, the fact that no one can account for them is frightening residents. Some have even talked about shooting the drones down, but that's not a good idea. The mystery drones are reportedly up to six feet in length. If the drones happen to weigh more than 55 pounds, they technically could be considered to be aircraft."If that's a legal registered drone, if you shoot it down, you are essentially shooting an aircraft down. So that is definitely illegal," Huang said."Registered or not, it's going to be dangerous. The batteries on these things are very flammable," Enos said.Enos believes if it's agricultural information the people behind the drones are after, the general public shouldn't be too worried."I think people are concerned, especially people that aren't familiar with drones and the technology," Enos said.The Nebraska State Patrol tweeted Monday that they are working with several sheriff's offices, local police departments and federal authorities to figure out who is behind the drone activity.The FAA has also stated they are aware of the sightings and are investigating.This story was originally published 2217

lawyers representing Covington Catholic student Nicholas Sandmann announced plans to seek an even bigger financial concession from CNN: 5,000,000. “CNN’s agenda-driven fiction about Nicholas and the January 18 incident was not only false and defamatory, it created an extremely dangerous situation by knowingly triggering the outrage of its audience and unleashing that outrage,” lawyer L. Lin Wood wrote in the new suit, which was filed Tuesday in the Eastern District of Kentucky.CNN declined WCPO's request for comment. Sandmann, 16, became the subject of widespread press coverage after videos of a January 18 encounter among Covington Catholic students, members of a fringe religious group known as the Black Hebrew Israelites and Native American demonstrators were widely disseminated online. Much of the initial coverage, including that of the Post, shared the story told by Native American demonstrator Nathan Phillips: That he and other members of the Indigenous Peoples March felt surrounded and threatened by the students, almost all of whom were white and many of whom wore red “Make American Great Again” caps, and that some taunted them with chants of “Build that wall!” “It was getting ugly, and I was thinking: ‘I’ve got to find myself an exit out of this situation and finish my song at the Lincoln Memorial,’ ” Phillips 1343

Worldwide markets plummeted again Thursday, deepening a weeklong rout triggered by growing anxiety that the coronavirus will wreak havoc on the global economy. The sweeping selloff pushed the Dow Jones Industrial Average down nearly 1,200, its biggest one-day drop ever.The benchmark S&P 500 dropped down4.4% Thursday, its worst one-day drop since 2011.The S&P 500 has now plunged 12% from the all-time high it set just a week ago. That puts the index in what market watchers call a "correction," which is decline of at least 10% from a high. The six-day correction is the fastest in history.Stocks are now headed for their worst week since October 2008, during the global financial crisis.The losses extended a slide that has wiped out the solid gains major indexes posted early this year. Investors came into 2020 feeling confident that the Federal Reserve would keep interest rates at low levels and the U.S.-China trade war posed less of a threat to company profits after the two sides reached a preliminary agreement in January. Even in the early days of the outbreak, markets took things in stride.But over the past two weeks, a growing list of major companies issued warnings that profits could suffer as factory shutdowns across China disrupt supply chains and consumers there refrain from shopping. Travel to and from China is severely restricted, and shares of airlines, hotels and cruise operators have been punished in stock markets. As the virus spread beyond China, markets feared the economic issues in China could escalate globally.One sign of that is the big decline in oil prices, which slumped on expectations that demand will tail off sharply."This is a market that's being driven completely by fear," said Elaine Stokes, portfolio manager at Loomis Sayles, with market movements following the classic characteristics of a fear trade: Stocks are down. Commodities are down, and bonds are up.The Dow dropped 1,190.95 points, its largest one-day point drop in history, bringing its loss for the week to 3,225.77 points, or 11.1%. To put that in perspective, the Dow's 508-point loss on Oct. 19, 1987, was equal to 22.6%. Bond prices soared again Thursday as investors fled to safe investments. The yield on the benchmark 10-year Treasury note fell as low as 1.246%, a record low, according to TradeWeb. When yields fall, it's a sign that investors are feeling less confident about the strength of the economy.Stokes said the swoon reminded her of the market's reaction following the Sept. 11, 2001 terrorist attacks."Eventually we're going to get to a place where this fear, it's something that we get used to living with, the same way we got used to living with the threat of living with terrorism," she said. "But right now, people don't know how or when we're going to get there, and what people do in that situation is to retrench."The virus has now infected more than 82,000 people globally and is worrying governments with its rapid spread beyond the epicenter of China.Japan will close schools nationwide to help control the spread of the new virus. Saudi Arabia banned foreign pilgrims from entering the kingdom to visit Islam's holiest sites. Italy has become the center of the outbreak in Europe, with the spread threatening the financial and industrial centers of that nation.At their heart, stock prices rise and fall with the profits that companies make. And Wall Street's expectations for profit growth are sliding away. Apple and Microsoft, two of the world's biggest companies, have already said their sales this quarter will feel the economic effects of the virus.Goldman Sachs on Thursday said earnings for companies in the S&P 500 index might not grow at all this year, after predicting earlier that they would grow 5.5%. Strategist David Kostin also cut his growth forecast for earnings next year.Besides a sharply weaker Chinese economy in the first quarter of this year, he sees lower demand for U.S. exporters, disruptions to supply chains and general uncertainty eating away at earnings growth.Such cuts are even more impactful now because stocks are already trading at high levels relative to their earnings, raising the risk. Before the virus worries exploded, investors had been pushing stocks higher on expectations that strong profit growth was set to resume for companies after declining for most of 2019. The S&P 500 recently traded at its most expensive level, relative to its expected earnings per share, since the dot-com bubble was deflating in 2002, according to FactSet. If profit growth doesn't ramp up this year, that makes a highly priced stock market even more vulnerable.Goldman Sach's Kostin predicted the S&P 500 could fall to 2,900 in the near term, which would be a nearly 7% drop from Wednesday's close, before rebounding to 3,400 by the end of the year.Traders are growing increasingly certain that the Federal Reserve will be forced to cut interest rates to protect the economy, and soon. They are pricing in a 96% probability of a cut at the Fed's next meeting in March. Just a day before, they were calling for only a 33% chance, according to CME Group.The market's sharp drop this week partly reflects increasing fears among many economists that the U.S. and global economies could take a bigger hit from the coronavirus than they previously thought.Earlier assumptions that the impact would largely be contained in China and would temporarily disrupt manufacturing supply chains have been overtaken by concerns that as the virus spreads, more people in numerous countries will stay home, either voluntarily or under quarantine. Vacations could be canceled, restaurant meals skipped, and fewer shopping trips taken. "A global recession is likely if COVID-19 becomes a pandemic, and the odds of that are uncomfortably high and rising with infections surging in Italy and Korea," said Mark Zandi, chief economist at Moody's Analytics. The market rout will also likely weaken Americans' confidence in the economy, analysts say, even among those who don't own shares. Such volatility can worry people about their own companies and job security. In addition, Americans that do own stocks feel less wealthy. Both of those trends can combine to discourage consumer spending and slow growth.MARKET ROUNDUP:The S&P 500 fell 137.63 points, or 4.4%, to 2,978.76. The Dow fell 1,190.95 points, or 4.4%, to 25,766.64. The Nasdaq dropped 414.29 points, or 4.6%, to 8,566.48. The Russell 2000 index of smaller company stocks lost 54.89 points, or 3.5%, to 1,497.87.In commodities trading Thursday, benchmark crude oil fell .64 to settle at .09 a barrel. Brent crude oil, the international standard, dropped .25 to close at .18 a barrel. Wholesale gasoline fell 4 cents to .41 per gallon. Heating oil declined 1 cent to .49 per gallon. Natural gas fell 7 cents to .75 per 1,000 cubic feet.Gold fell 40 cents to ,640.00 per ounce, silver fell 18 cents to .66 per ounce and copper fell 1 cent to .57 per pound.The dollar fell to 109.95 Japanese yen from 110.22 yen on Wednesday. The euro strengthened to .0987 from .0897. 7132
