In a series of alarming incidents, several Delta Air Lines flights experienced smoke and haze onboard, prompting emergency landings and evacuations. A flight from Atlanta to Columbia had to turn around after passengers reported haze inside the aircraft, and multiple flights returning to Atlanta faced similar issues. Passengers were forced to evacuate via emergency slides at Atlanta airport, with reports of smoke filling the cabin in at least two instances across multiple flights. Notably, a Sydney-bound flight was diverted back to Los Angeles due to smoke detected midair, highlighting ongoing safety concerns. These emergencies unfolded on the same day, causing significant distress among passengers and necessitating swift action from flight crews.
