瑞典跟美國都出現無人機侵入核電廠的奇怪事件?
"The United States has seen its share of unidentified drone incursions lately. We previously reported on an absolutely bizarre drone incursion above the Palo Verde nuclear power plant in Arizona which remains unexplained to this day. U.S. Nuclear Regulatory Commission (NRC) documents show that Palo Verde is far from the only nuclear facility to have had such incursions and that as many as 60 different drone sightings took place at 24 nuclear power facilities between 2015 and 2019. The NRC and National Nuclear Security Administration appear to be finally taking the situation seriously by making moves to deploy anti-drone systems at sensitive sites."
