British Airways flight BA295 from London Heathrow to Chicago O'Hare declared a mid-air emergency over Ireland on October 5, 2026, plunging from cruising altitude of about 37,000 feet to just 9,000 feet within minutes before turning back to London.
What happened to BA295
BA295, a scheduled 8-hour-40-minute transatlantic service from London Heathrow's Terminal 5 to Chicago O'Hare International Airport, departed on Monday morning at about 11:50 am local time, roughly 40 minutes behind schedule. The aircraft was a Boeing 777-200ER, registration G-VIIA.
About one hour after takeoff, while cruising at around 37,000 feet over Ireland, the aircraft began a sudden, steep descent — dropping roughly 28,000 feet to about 9,000 feet within minutes. The Sun reported the drop took just seven minutes.
7700 squawk and return to Heathrow
During the descent the flight crew transmitted squawk 7700, the international transponder code for a general emergency. Flight-tracking service Flightradar24 confirmed on X: "#BA295 from London to Chicago squawking 7700 and descended down to 9000 feet above Ireland."
The Chicago leg was abandoned. Instead of continuing across the Atlantic, the 777 reversed course and headed back to London Heathrow. Before landing, the jet entered holding patterns to reduce fuel weight — reports put roughly 30 tonnes of fuel still aboard, with no fuel jettison; the landing gear was lowered to burn fuel and reach a safer landing weight.
Emergency response teams at potential diversion airports including Shannon and Dublin were placed on standby as a precaution.
Possible cause: unconfirmed pressurization issue
British media cited an "unexpected operational issue," but British Airways had not confirmed a specific cause at the time of reporting. Unconfirmed social-media reports pointed to a possible pressurization issue; aviation reporters note that a controlled descent below 10,000 feet is the standard protocol for cabin depressurization events.
No passenger or crew numbers were reported in the coverage available, and the story was still developing as the aircraft circled near the UK coast in the afternoon.
The incident follows a wave of aviation emergency alerts in recent months and will likely draw close scrutiny from UK aviation investigators once the aircraft is on the ground.
