Part 4/8:
As the day progressed, complications arose with growing urgency. Controllers were tasked with managing both regular air traffic and monitoring unusual behaviors from two aircraft, American Airlines Flight 11 and United Airlines Flight 175. These flights were eventually recognized as hijacked, forcing controllers to prioritize their communications and coordinate a plan of action.
Emergency Responses and Actions
As awareness of the hijackings grew, controllers worked to alert other air traffic in the vicinity about the impending danger. Clearances were issued for safe distances, and corrective action was taken to prevent potential collisions. Communication involved issuing warnings and directing aircraft to avoid specific paths where hijacked planes were believed to be operating.
