A plane departing Dundee for the UK capital was forced to turn back following a mid-air scare.
Flights arriving at and leaving the city had to be axed after the warning light on the Loganair service departing from Dundee Airport came on as it passed above South Lanarkshire.
The flight left the airport at 7am and was bound for London Stansted with 20 passengers before being forced into the U-turn.
A warning indicator flashed on in the cockpit of the Saab 340 plane and it returned to Dundee Airport as a “precautionary measure”.
A further flight, the 10.30am arrival into the city, was axed after the issue was reported.
Staff at Loganair said there were no safety concerns during the incident on the BE6621 flight.
The firm added the warning had transpired to be a “false alert” but that it had to be investigated for the “safety of passengers”.
Those on board were offered a refund for the journey or an alternative flight to Stansted from Edinburgh via Easyjet – with four people choosing the later.
A spokesperson for Loganair said: “Flight BE6621 was en route from Dundee to London Stansted carrying 20 passengers and three crew when a warning indicator signalled in the cockpit.
“The captain took the precautionary measure to return to Dundee Airport where the Saab 340 aircraft landed safely.
“Loganair is making alternative travel arrangements for passengers and would like to apologise for the disruption this interruption has caused.”
A Dundee Airport spokesperson said: “Airport staff worked closely with all the passengers involved to ensure there was as little disruption as possible to travel plans as a result of this morning’s flight cancellation and normal flight patterns to Stansted resumed later in the day.”
