Although there are many start-up technology companies working on solutions for UAV-related risks, such as building a "fail-safe" drone controller and software that can sense when someone is in the way, the safety of drones operating over people not directly involved in the operation remains an issue. For example, in early 2017, a small unmanned aerial vehicle (UAV) operated by Norwegian company Kongsberg crashed into a building near the royal palace in Oslo and livestreamed what happened. The drone operator was broadcasting live video of himself as he flew the device above the city streets. The crash occurred after apparently flying too close to several people who were out walking and crossing the street. One bystander suffered minor injuries from being hit by shrapnel from the propeller. As of late 2018, the Federal Aviation Administration is still investigating the cause of the crash. In February 2019, it was announced that Kongsberg would be fined $120 thousand (NOK 1 million) by Norwegian aviation
