[Nationwide Grounding Order in the US Imminent, After Initially Dragging Down US Stocks and Airline Stocks] According to BlockBeats on November 14, Air Current reports that the nationwide grounding order in the United States is about to be lifted. Following the Federal Aviation Administration's (FAA) nationwide grounding order for all airports issued on Friday due to special circumstances, ETFs tracking the S&P 500 fell as much as 0.5% in after-hours trading. ETFs tracking the Nasdaq 100 fell as much as 0.8% in after-hours trading. Airline stocks were also dragged down by the news, with United Airlines down 1.2%, JetBlue Airways down 2.4%, and American Airlines down 1.7%. Conversely, cybersecurity stocks rose: Palo Alto rose 2%, Zscaler rose 1%, and Crowdstrike rose 2%. The grounding was related to a failure in air traffic control (ATC) communication frequencies. U.S. Transportation Secretary Sean Duffy previously stated that all air traffic control centers were affected by communication problems, and technicians were investigating the cause of the malfunction. The FBI, however, believes that the communication failure affecting the air traffic control system was not caused by a cyberattack or criminal activity. Investigators are currently checking whether the malfunction is related to a software update.
