Scots found themselves looking skyward yesterday after spotting an unusual military aircraft making circles over Glasgow Airport - the latest in a series of sightings in recent days.
The Bell Boeing V-22 Osprey was spotted in the skies over Glasgow at around 6.30pm before landing outside of the city.
While it has a plane-like fuselage, the Osprey makes use of two helicopter-style rotors which means it can take off vertically rather than needing to use a runway to get off the ground.
A snap of the aircraft sitting at Glasgow Airport was captured by enthusiast photographer Thomas Flynn.
Pictures and video of the unique tilt-rotor aircraft were also shared by curious locals on social media.
One person said on Twitter: "Unusual plane circling low over Glasgow east end at 18.29 today. Not on flight radar. Potentially a Bell-Boeing Osprey?"
Another added: "V22 Osprey flying over Glasgow right now. This normal here now?"
Glaswegian users of message board website Reddit were impressed by the distinctive airship.
"Saw it myself above Partick. Pretty wild bit of kit," one noted.
While the origin and ultimate destination of the aircraft are unknown - as military aircraft movements are largely hidden from publicly accessible platforms like FlightRadar24 - Ospreys have been spotted in UK airspace in the past.
The United States Air Force (USAF) keeps the aircraft at RAF Mildenhall in Suffolk, where it is used by the 7th Special Operations Squadron for top-secret missions involving US special forces.
Mildenhall, together with its sister base Lakenheath, is under control of USAF despite being a British military base.
Scots on the east coast were treated to the sight of a squadron of USAF planes earlier this month.
The formation of fighter jets and a tanker plane used for refuelling was spotted over Fife in the east and the Isle of Skye in the west as it headed out over the Atlantic to return home.
And earlier this week Glaswegians spotted a huge Royal Air Force plane completing loops over the city as part of a night-flight training exercise.
