Airlines globally began pulling Airbus A320 aircraft from service after the manufacturer ordered an immediate software update on up to 6,000 jets, marking one of the largest recalls in the company's history. The directive follows an incident involving an "uncommanded and limited pitch down event" linked to a software vulnerability that could be triggered by intense solar radiation. Delta Air Lines, which operates the aircraft, stated that it expects to complete the necessary software fix quickly. The carrier also said that it anticipates any "resulting operational impact" from the widespread recall should be limited, suggesting minimal disruption to its flight schedules.
