The US Air Force's Boeing E-4B Nightwatch, nicknamed the 'Doomsday Plane,' made a rare public appearance with flights over Washington D.C. and landing in Los Angeles. This highly survivable airborne command center, designed for national emergencies and nuclear war, sparked speculation due to its unusual presence and lack of official explanation amid global tensions. Defense Secretary Pete Hegseth was reportedly aboard for part of the journey. While officials have not linked the flights to specific events, the timing has fueled public discussion and online theories.
