A pilot and his student had a lucky escape after their plane was forced to make an emergency landing near an east Perthshire farm.
The light aircraft came down near Kettins, about two miles from Coupar Angus, just before 3pm.
Emergency services, including about a dozen firefighters, were scrambled to the scene at Newton of Ballunie.
Both men were said to have walked away uninjured from the damaged Cessna 152 craft.
The plane was seen sitting in the empty field with its front end in the soil.
The Department for Transport’s Air Accident Investigation Branch (AAIB) confirmed a probe is now under way.
A police spokesman said: “Police Scotland and other emergency services attended at a forced landing of a light aircraft at Kettins, near Coupar Angus.
“Both occupants of the aircraft are safe and the circumstances of the incident are now under investigation.”
It is understood the plane may have suffered engine trouble while flying above Perthshire, forcing its pilot to make an emergency touchdown.
Locals said the pair were taking part in a training exercise when problems struck. The weather was favourable at the time, with blue skies and sunshine.
One resident said: “The road was blocked with fire engines and police cars. There was crewmen everywhere.
“It looked really serious, so its good to hear no one was seriously hurt. They were very lucky.”
She added: “The front of the plane appeared to have hit the dirt and it suffered some damage, but not a lot. The firemen were helping the pilot check for damage.”
A fire service spokeswoman confirmed crews attended at the incident.
An AAIB spokesman added: “This incident has been reported to us and an investigation will be carried out.”
The pilot will be quizzed by letter in the first phase of the inquiry.
No one at Perth Airport was willing to discuss the incident.
The accident happened just a few miles from Abernyte, where two men were killed in a plane crash in 2015.
The light aircraft, which departed from Inverness, was heading to Dundee airport when it lost control during bad weather.
It sparked a large-scale search involving police, coastguard teams and the RAF.
