A Delta Air Lines Boeing 767-400 made headlines when it was forced to perform an emergency landing at Shannon Airport (SNN) in Ireland after experiencing a cockpit window overheating issue. The flight, designated DL4, was en route from London-Heathrow Airport (LHR) to New York’s John F Kennedy Airport (JFK) on March 18, 2025, with 129 passengers on board.

Departing LHR at approximately 4:24 p.m., the aircraft with registration N825MH ran into trouble about two hours into the journey, prompting a declaration of a general emergency and activating the distress signal 7700. The pilot quickly descended to 10,000 feet as emergency vehicles prepared for their arrival on Runway 06 for brake inspections.

A spokesperson from Delta Air Lines confirmed that the flight crew had spotted heat issues with the cockpit's window, leading the captain to execute standard emergency landing procedures at the nearest suitable airport, Shannon. Fortunately, the aircraft touched down safely, and all 129 passengers, including the three pilots and nine flight attendants, were evacuated without any reported injuries.

Following an overnight stay at Shannon Airport for inspection, the passengers resumed their journey to JFK Airport the next afternoon. Delta Air Lines expressed regret for the inconvenience caused to its customers, emphasizing that safety remains their top priority. "As nothing is more important than safety, the crew of Delta flight 4 followed standard procedures to divert to Shannon, Ireland after observing a mechanical issue. The flight landed safely and customers deplaned at an arrival gate," the statement read.
