Prayers of remembrance will be offered at a church service on Sunday in honour of those involved in the Eastwood Toll helicopter crash of 1990.
January 24 marks the 25th anniversary of the tragedy that claimed the life of one policeman and injured others.
The Clyde Helicopter was on loan to Strathclyde Police and dealing with a robbery in Barrhead when it hit the top floor of McLaren Court, an elderly residence near Eastwood Toll.
The helicopter fell 70ft to the ground, killing sergeant Malcolm Herd (32).
Civilian pilot Graham Pryke was taken to hospital in critical condition according to reports at the time, while two other officers — John Muir and William Shields — were treated for injuries.
The accident was blamed on a snowstorm and resulted in the residents of the building being evacuated, although no one inside was hurt.
Giffnock Community Council are marking the date 25 years on, alongside representatives from East Renfrewshire Council and Police Scotland.
Chair Savio D’Souza told The Extra: “It’s important to remember that, sometimes, those who work for our emergency services are called upon to give the ultimate sacrifice while protecting their communities.
“All people, regardless of faith, are welcome along to our special remembrance service for those affected by the tragedy, and for refreshments afterwards in the church hall.”
The service starts at 11am on Sunday at Giffnock South Church.
