British Airways flight that declared a state of emergency over Ireland issues alert 7700 – What is it? Explained | Today’s news
A British Airways flight from London to Chicago declared an emergency on Monday after plummeting about 9,000 feet, according to online flight tracking website FlightRadar24. BA295 was shouting “7700” – the code used by pilots to declare a general emergency.
The plane, which departed Heathrow’s Terminal 5 at around 11.50am (local time), declared an emergency while flying over Ireland. It was scheduled to land in Chicago but was diverted back to London.
The Boeing 777-200ER aircraft was scheduled to take around 8 hours and 40 minutes to reach Chicago O’Hare International Airport (ORD), PTI reported.
But about an hour after takeoff, Flightradar24 data reportedly showed the plane had reached its cruising altitude of 37,000 feet when it appeared to hit a problem. Then the 7700 started beeping.
Flight tracking data showed that the plane subsequently began a rapid descent, dropping 28,000 feet to an altitude of 9,000 feet within minutes.
The aircraft then flew south of Wales and over south-west England before making several turns over the English Channel as it headed back towards London.
The Boeing 737-8 was carrying 174 passengers, including children. The aircraft was eventually diverted to Prince Sultan Bin Abdulaziz Airport in Tabuk, Saudi Arabia.
The plane’s circling over Europe could potentially be related to fuel management.
