British Airways flight travelling from London to Chicago declared an emergency while flying over Ireland on Monday after reportedly making a sudden descent of around 28,000 feet, according to flight-tracking data cited by UK media. According to media reports, British Airways Flight BA295, operating from London Heathrow Airport to Chicago O'Hare International Airport, reportedly transmitted the 7700 emergency transponder code while flying over Irish airspace.

The squawk 7700 code is an internationally recognised signal used by aircraft crews to alert air traffic control to a general emergency. The signal allows controllers to immediately identify the aircraft and provide the necessary assistance.

Flight makes a U-turn

However, about an hour after take-off, the aircraft had climbed to its cruising altitude of 37,000 feet when it appeared to encounter an issue and was squawking the international aviation signal for a general emergency. Flight-tracking data shows the aircraft initiated a rapid descent, dropping 28,000 feet to an altitude of 9,000 feet within minutes. The nature of the emergency is not yet clear, and a statement from the airline is awaited.

Later, the flight-tracking site reported that the plane made a U-turn and is now heading back to its origin.
