British Airways flight 2PD, a scheduled service from London Heathrow to Chicago, returned to Heathrow for an emergency landing after a rapid 27,000‑foot descent minutes after takeoff. The aircraft left at 11:50 a.m., climbed to roughly 35,000 feet, and then lost altitude.
The drop occurred about 30 minutes after departure and was linked to a technical issue reported on the plane. The airline followed emergency procedures and the aircraft landed at Heathrow.
