A plane was forced to return to Edinburgh Airport after declaring an in-flight emergency.

The Loganair flight LOG321, which was flying from Edinburgh to Southampton on Monday morning, declared a Squawk 7700 while flying over Dumfries.

It performed a u-turn at the Scottish Borders.

The flight was due to arrive in Southampton at 8.20am, but instead landed at Edinburgh.

Bosses at Loganair have now confirmed to The Herald that the plane suffered a fault with one of the pressurisation components.

Crew members acted on board the aircraft before it returned to Edinburgh Airport.

An emergency squawk is used to identify an aircraft which has a possible issue and enables it to have priority over other air traffic.

Loganair’s chief operations officer Maurice Boyle told The Herald: “Following an alert of a fault with one of the pressurisation components on flight LM321 to Southampton, the crew carried out the appropriate actions and returned to Edinburgh Airport.

“We regret the inconvenience caused to our customers. Flight Safety is our top priority and we’re grateful to all parties involved including Edinburgh Airport for their support and assistance.”
