A 16-year-old boy and an 80-year-old man have died after a light aircraft crashed near Drymen, close to Loch Lomond in Scotland, prompting an investigation by aviation authorities.

Police Scotland said emergency services were alerted to the incident at approximately 4:45 p.m. on Friday. Both occupants were pronounced dead at the scene, and their families have been informed.

The aircraft, identified as a Piper Tomahawk II, departed Glasgow Airport at 4:17 p.m. before losing its transmission signal about 20 minutes later, in an area a few miles northeast of Drymen.

Flight records indicate that the aircraft had earlier taken off from Cumbernauld Airport at 11:46 a.m., travelling to Glasgow Airport after a flight of approximately 15 minutes.

It subsequently departed Glasgow at around 1 p.m. for a roughly two-hour journey northeast towards Newport-on-Tay before returning to Glasgow. The aircraft remained at the airport for slightly more than an hour before embarking on the flight that ended in the fatal crash.

The Air Accidents Investigation Branch has commenced inquiries to establish the circumstances surrounding the incident. Temporary restrictions have also been imposed on airspace around the crash site while investigations continue.

Authorities have yet to disclose further details about what caused the aircraft to go down or the identities of the two victims.

The investigation is expected to examine the aircraft’s final movements and other available evidence to determine the events leading to the crash.
