A TAP aircraft scheduled to fly from Lisbon to London Heathrow makes an unscheduled diversion to Porto after a “strange noise” is reported. According to one report, the aircraft is TAP flight TP2678. The diversion is attributed to a suspected issue involving the landing gear, with the report claiming that an airport worker left headphones attached to the front landing gear, which leads to the noise and prompts corrective action. The accounts state that the flight does not continue directly to Heathrow as planned and instead lands in Porto. Other than the cause cited in the report and the change in destination, the available information does not specify additional details such as passenger impacts, how long the aircraft remains on the ground, or whether the headphones are recovered and inspected. The incident is presented as a operational mishap linked to airport staff equipment, resulting in a safety-driven reroute for the flight.
