U.S. officials have ordered a 2-day stand down for all military aviation inside as well as outside the United States after an F-35 jet went missing in South Carolina.

According to ABC News, “no units are allowed to fly” unless there is a discussion for two days about “safety measures and procedures.”

“No units are allowed to fly until they have a two-day discussion about safety measures and procedures, the commandant said in a service-wide email on Monday.”
