British Airways Flight to Chicago Returns to London After Dropping 28,000 Feet

British Airways flight BA 295 diverted back to Heathrow International Airport and cancelled its trip to the United States after plunging 28,000 feet and declaring an emergency. Flight-tracking website Flightradar24 recorded the sudden midair descent while the aircraft was flying over Ireland. The plane, a Boeing 777-200ER registered as G-VIIA, left Heathrow Airport Terminal 5 at 11:50 am on Monday local time. It had a planned flight time of 8 hours and 40 minutes to Chicago O'Hare International Airport.

What Happened

Almost an hour after taking off, the aircraft reached a cruising altitude of 37,000 feet before running into an unexpected operational issue that forced the emergency response, according to reports from UK news outlets.

Context

Commercial aircraft cruising at high altitudes like 37,000 feet carry backup systems and oxygen masks that deploy automatically if cabin pressure drops or if other urgent technical problems occur. Pilots follow strict safety rules to quickly lower the plane to a safer altitude and return to the nearest suitable airport when unexpected issues arise.
