An early morning flight from Aberdeen International airport to Shetland had to turn back after declaring an emergency.
The Loganair service took off at about 6.54am flying to Sumburgh airport, which is a hub for oil and gas industry flights.
However, the flight declared an emergency while on-route to the island and was forced to fly back to Aberdeen.
Images from Radarbox, a plane tracker, show the aircraft coming full-circle after flying across the north sea.

The LM901 flight landed back at Aberdeen safely at about 8.15am.
Loganair confirmed that the crew on-board made the decision to turn back due to an “alert of a fault” with the right-hand engine.
A spokeswoman added: “The passengers will resume their journey on a replacement Loganair aircraft this morning, and engineering checks to identify the cause of the warning indication are already underway.
“We apologise to customers for the disruption to their journey, yet ask for their understanding that safety is always our first priority.”
Aberdeen International airport has been approached for comment.
