TAP flight returns to Lisbon following in-flight emergency

A TAP Air Portugal flight bound for Curitiba, Brazil, returned to Lisbon on Saturday after the captain declared an emergency. The Airbus A330 experienced a suspected depressurization issue at 30,000 feet, prompting a descent to 10,000 feet and a fuel-dumping maneuver before landing safely. No injuries were reported among those on board.
