Climbing is a sport that's getting more and more popular. For the first time next year, it’ll be an Olympic sport. Additionally, a documentary featuring professional rock climber Alex Honnold took the Oscar win at this year’s Academy Awards!After filming climbers for two decades, filmmaker Peter Mortimer is happy to see more people taking notice. As amazing as it is to see the shots he captures, what may be more breathtaking is what you don’t see: the work behind the scenes. It’s all to bring the world of climbing out of the wilderness and onto the big screen “There's no stadium, there's no arena and nobody really knows what they're doing,” Mortimer says. Mortimer is a climber and the co-founder of Sender Films, the company that produced “The Dawn Wall.” Mortimer and his team followed two men as they attempted to climb a 3,000-foot rock face in Yosemite National Park. The film captured the climbers’ journey from hanging from the wall to even sleeping on the wall. “We knew if they did it, we had to be there,” Mortimer says. “But we also said, for seven years really, were like this is probably never going to happen, but it's worth the risk.” It took the climbers seven years to finally make it. Mortimer and his team were there to capture the moment. Then, the film received more awards than Mortimer ever imagined. One film led to another, and as the climbing industry grew, so did Sender Films. The company has produced more than 40 hours of climbing films, winning two Emmys and putting on a film tour with more than 400 shows around the world. “I thought rock climbing was something that was just a little a little hobby at the time, and I’m just still surprised what it's become,” says Zachary Barr, a director with Sender Films. However, there have been challenges. “I've seen so many of my, you know, really close friends die in the mountains,” Mortimer says. But the filmmaker says he's approached this journey in film, as he would a climb. “No one's climbed that like. That could be an amazing thing, that the path doesn't really exist,” he says. 2085

Facebook announced in a blog post on Wednesday that it will begin banning posts that praise and support white nationalism and separatism."It’s clear that these concepts are deeply linked to organized hate groups and have no place on our services.," Facebook said in the blog.Facebook says that posts in support of white supremacy have always been banned under its policy. However, the platform determined that white nationalism and white separatism "cannot be meaningfully separated from white supremacy and organized hate groups" after spending months discussing the matters with academics.While white supremacists believe that white people are superior to people of other races, white nationalists believe that the United States is a "white nation" and that white people should continue to maintain a dominant economic and political dominance in the country. White separatists believe that white people should establish their own states and remove minorities from their communities. In their blog post, Facebook explained that in the past, they had conflated white nationalist and white separatist content with that of other non-hate speech — "things like American pride and Basque separatism," Facebook wrote.Facebook said it would use machine learning in order to quickly remove this kind of hate speech from the platform. They also announced that they will attempt to direct users who search for white supremacist content on the website to resources that help people leave hate groups.For more Facebook's new policy, 1534

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
