A British Airways flight from London to Chicago (BA295) declares an emergency while flying over Ireland after a rapid, steep descent. Multiple outlets report the aircraft transmits the aviation emergency code 7700 during the incident.

Flight tracking information cited by outlets says the Boeing 777 descends from cruising altitude down to about 9,000 feet within minutes. One report describes the descent as from roughly 28,000 feet, while others focus on the lower altitude reached during the emergency. The flight then makes a U-turn and returns toward London’s Heathrow after the alert.

The coverage generally agrees on the flight route and timing around late morning departure from Heathrow. Differences are mainly in how the descent is described—some outlets specify the approximate height dropped, while others summarize the emergency as a descent to around 9,000 feet. All accounts attribute the emergency declaration to the in-flight alert transmitted with code 7700, with subsequent return flight actions reported as a result.
