Pilots had to request a priority landing at Glasgow Airport as a precaution due to a passenger medical issue on board a flight.
The incident involved a British Airways flight travelling from London Heathrow, which departed the capital at 7:30am this morning.
Flight tracking site Flightradar24 shows the plane descended rapidly from 31,000 ft to 11,000 ft in a matter of minutes on approach to Glasgow as it flew above Cumbria and Dumfries and Galloway.
