Ian Haggis - pictured when he was younger - died when the light aircraft crashed near Loch Lomond

An 80-year-old man who died in a light aircraft crash is understood to be flying instructor Ian Haggis.

He and a 16-year-old boy died when their plane came down near Loch Lomond. The teenager's identity has not been released.

The pair had flown out from Glasgow Airport at 16:17 and stopped transmitting at 16:37, a few miles north east of the village of Drymen near Stirling.

Emergency services were called to the crash at about 16:45 on Friday.

Temporary airspace restrictions are currently in place over the area while the Air Accidents Investigation Branch (AAIB) carries out its inquiries.

Old Drymen Road, near the scene of the crash, remains closed with vehicles being turned around and hillwalkers rerouted.

Tributes posted on social media by former students describe the flying instructor as "a gentleman and an experienced aviator", and a "good friend".

The plane - a Piper Tomahawk II aircraft - is registered to Leading Edge Flight Training in Renfrew, according to the Civil Aviation Authority's aircraft register., external

Previous social media posts on Leading Edge's Facebook page report the instructor's nickname as the 'Flying Haggis', and show that he had been working with the flying school.

A spokesperson for Leading Edge Flight Training said: "We are devastated by this tragic accident involving one of our aircraft and two close members of our Leading Edge family.

"Our thoughts and deepest sympathies are with the families, friends and loved ones of those who lost their lives.

"Leading Edge Flight Training is assisting with the investigation and while it remains ongoing we are unable to say anything further at this time."

Stuart Abernethy told BBC Scotland News that he witnessed the last few moments of the plane's journey from his driveway.

"I was standing in the drive and I heard an aircraft engine over-revving," he said.

"I looked up... and I saw probably for about the last 10 seconds a light aircraft coming down in a spiral. I didn't see it land and I didn't hear anything - but I just saw it vanish from sight.

"There was no smoke, no impact sound or anything like that. And then nothing."

He added: "It was low and it wasn't in a sort of dive trajectory, it just literally fell out of the sky in a spiral with the engine revving and then a total silence after that.

"Normally we hear training flights and hear them recover and minutes later they appear and you're relieved. But there was just deathly silence after that."

Later, his daughter saw the news about the crash on social media.

"It was very unpleasant to see, it's scary to see actually - and then when you learn that some people had lost their lives, it's a very distressing experience."

Police remained at the scene on Sunday and blocked off Old Drymen Road near the crash

Gavin Birch-Williams, managing director of Glasgow Airport, said: "We are aware of an incident involving a light aircraft that departed from Glasgow Airport.

"This is a deeply tragic event, and the thoughts and heartfelt sympathies from all at Glasgow Airport are with the friends and families affected."

The plane had earlier taken off from Cumbernauld Airport at 11:46, before flying 15 minutes to Glasgow Airport.

It stayed there until about 13:00, before doing a two-hour flight north east to Newport-on-Tay then turning round and heading back to Glasgow.

It was on the ground at the airport for just over an hour before it took off again and started its final flight.
