Close calls between drones and airplanes are on the rise. Researchers now say drones could be more deadly than collisions with birds.Pilot Jake Fredericks was coming in for a landing when he says a drone shot up right in front of him, coming up through the clouds when he was on instrument approach.He estimates it was only 200 feet in front of him."I felt like my life flashed before my eyes, you know if we would have hit that thing, that could have potentially been death for us," he said.Pilot Jeff Munford told us last year about his close call with a drone as he flew over the Georgia-Florida line. Nationwide, reports of drone sightings by pilots has shot up nearly 91 percent since 2015.FAA rules prohibit people from flying drones within five miles of an airport or above 400 feet without permission.The I-Team found Florida pilots reported 288 close calls with drones last year, including two dozen in the Tampa Bay area.Kevin Poorman of the University of Dayton's research institute has been doing bird strike testing for more than two decades.His researchers fired both a replica bird and a two pound drone at a wing."If you look from the exterior, it looks like the bird does more external damage, but the drone had the ability to immediately puncture right through and carry farther to do more damage," Poorman said. "If you go to a 10 pound drone, that's five times the energy."Pilot and Drone instructor Jason Lorenzon believes it's important to teach drone pilots the rules of the sky, especially as the FAA expects the number of drones to approach 3 million by 2022."You can go and pick one of these up off Amazon and it doesn't come with that extensive of a pilot operating handbook, let alone rules of the national airspace system. How do you expect Joe Consumer who just purchased it to know the rules?" he said. 1845

CHICAGO, Ill. – Contigo is recalling about 5.7 million of its kids water bottles because their clear silicone spouts can detach, posing a choking hazard to children.

The water bottles were sold individually as well as in two-packs and three-packs.The water bottles come in three sizes (13 ounce, 14 ounce and 20 ounce) and four colors (solid color, graphics, stainless steel and stainless steel solid colors).The CPSC says the base and cover of the clear silicone spout will always be black, and only black colored spout base and spout cover models are included in this recall. Contigo is printed on the rim and along the front near the bottom of the bottles.In addition to the water bottles, the recall also involves replacement lids that were given to consumers as part of an August 2018 recall of the same product. The CPSC says consumers should immediately stop using the recalled bottles and take them away from children. Consumers with the products should contact Contigo for a free replacement bottle. 1417

DUBAI, United Arab Emirates – United Nations experts have called for an "immediate investigation" by the United States into information they received that suggests that Jeff Bezos' phone was hacked after receiving a file sent from Saudi Crown Prince Mohammed bin Salman's WhatsApp account. Bezos owns The Washington Post and is the founder of Amazon. At a time when Saudi Arabia was supposedly investigating the killing of Saudi critic and Washington Post columnist Jamal Khashoggi and prosecuting those it deemed responsible, "it was clandestinely waging a massive online campaign against Mr. Bezos and Amazon targeting him principally as the owner of The Washington Post," the experts said in their statement.Investigators found that after Bezos got the video file in 2018, his phone began sending unusually large volumes of data, 845
